EASY ANSWERING BIOLOGY : DYNAMIC ECOSYSTEM

Suggest how a farmer can control the population of mice at his farm without the use of peticides.
Explain how the method works.
  • Use biological control
  • which involves prey-predator relationship
  • Predators such as snakes are used to catch the prey which is the mice.
  • Population of mice will decreases.
  • Predator must be specific / neutral.
  • Predator must not harm the plants in the farm.
  • This prey-predator interaction will ensure that the population of each other will be regulated in a cyclical manner which maintains the populations of both organisms in a dynamic equilibrium.

What is meant by "colonisation and succession in a habitat"? Explain how colonisation and succession bring about the formation of primary forest in a habitat.


MEANING
  • Colonization is a process whereby a species colonises and survives in a newly formed area.
  • Succession is a process when one species of organisms changes the habitat which results in the organisms to be succeeded/ replaced by other species which is more suitable to the habitat.
EXPLANATION
  • Activities of the pioneer species (submerged plants) cause a change in the habitat, make it more suitable to other species.
  • The remains of plants and decayed bodies deposited on the pond bed.
  • Water level in the pond decreases / Pond becomes shallower
  • which will add nutrients to the pond water and change the pH of the water.
  • This favours the growth of floating plants which replace the pioneer species.
  • Floating plants cover the water surface, preventing light from penetrating the water and causing slower rate of photosynthesis in the pond
  • causes many of the submerged plants to die and sink to the bottom of the pond.
  • Raising the pond bed / Making the pond more shallow.
  • Floating plants are gradually replaced by amphibious plants.
  • The successor causes further changes to the pond, making it unfavourable to the amphibian plants to grow.
  • Finally, the amphibious plants are replaced by a land community which dominates the area.


Explain why most plants cannot colonize and grow in the swamps.
  • The ground is too soft and unable to support plants.
  • The water-logged / muddy swamps provide very little oxygen for root respiration.
  • The swamp water has a high concentration of salt and is hypertonic.
  • The plants growing in the swamp will have the problem of dehydration.
  • Seeds that fall into the muddy swamp will die of dehydration / insufficiency of oxygen.
  • The swamp is exposed to strong sunlight and intense heat.
  • As a result, the plants growing there will lose water very fast by transpiration.


Explain how the mangrove trees adapt themselves to the harsh living conditions.


  • Root system which is highly branched and spreads over a big area to overcome soft mud problems.
  • Avicennia sp has extensive branching roots / Rhizophora sp has stilts roots / Bruguiera sp has buttress roots
  • for support the plants to trap soil particle.
  • Pneumatophores (breathing roots) which grow protruding upwards above the ground with lenticels
  • for gaseous exchange

 
  • Excess salt is eliminated through hydathodes 
  • found at the lower epidermis of leaves.
  • Viviporous seeds which germinate while still attached to the parents plant.
  • The long radical produced will let the seedling stick into the ground and not submerge or drift away.
  • Thick cuticle and sunken stomata 
  • which help to reduce the rate of transpiration
  • The plant cells have high concentration of cell sap.
  • The cells are able to withstand the high salt contents of the swamp.

Explain how nitrogen cycle maintain the content of nitrogen in the atmosphere through microorganisms, factory and lightning.

MICROORGANISMS
  • Nitrogen-fixing bacteria in the root nodules of leguminous plants and in the soil can convert atmospheric nitrogen
  • through nitrogen fixation process.
  • They fix atmospheric nitrogen and convert it into ammonium compounds.
  • The nitrates are then absorbed by the plants to make proteins.
  • When animal eat plants, the proteins are transferred to the animals.
  • When plant and animals die (or excrete nitogeneous substances) these dead organisms or nitrogeneous substances are broken down to ammonia by bacteria of decay.
  • Nitrosomonas sp convert ammonia into nitrite.
  • Nitrobacter sp convert nitrites to nitrates.
  • Denitrifying bacteria convert nitrates back to nitrogen to complete the nitrogen cycle.

FACTORY
  • Industrial process / Haber process
  • chemical reaction, oxygen plus nitrogen, produces chemical fertilizer / ammonium nitrite, urea
  • Industrial factory
  • release nitrogen dioxide which dissolved in water producing nitrus acid and changes to nitrate when react with metalic base in soil.

LIGHTNING
  • Nitrogen-fixation by lightning
  • produces nitrogen dioxide which dissolve in water to produce nitrite in the soil.

EASY ANSWERING BIOLOGY : CHEMICAL COMPOSITION OF CELL

Explain the principle of enzymatic reaction between enzyme and substrate.




  • The reaction is based on lock and key.
  • The enzyme reacts on the substrate.
  • The substrate molecules bind to the active site of the enzyme
  • to form enzyme-substrate complex.
  • The enzyme remains unchanged at the end of reaction. / The enzyme can be used again.
  • Products are produced at the end of reaction.

Decribe the production of extracellular enzyme.

  • The information for the synthesis of enzymes is carried by DNA in nucleus.
  • The information is copied and carried / transferred to ribosome through RNA / mRNA.
  • The information is used to synthesize protein in the ribosome.
  • Proteins that are synthesized in the ribosome are transported through the spaces between rough endoplasmic reticulum.
  • Protein depart from structure rough endoplasmic reticulum wrapped in transport vesicles the buds off the side of rough endoplasmic reticulum.
  • These transport vesicles fused with the membrane of golgi apparatus to be sorted and modified.
  • Modified protein is packed into secretory vesicle.
  • Secretory vesicles bud off from golgi apparatus membrane and sent to plasma membrane.
  • Secretory vesicles will release the modified protein / enzyme outside the cell (as extracellular enzyme).

EASY ANSWERING BIOLOGY : ENDANGERED ECOSYSTEM

A group of farmers planned to develop an agriculture nearby the lake. Explain the effect on the lake if their planning is not managed properly.

  • Farmers use fertilisers that usually contain nitrates and phosphates.
  • The leaching of chemical fertiliser from agriculture area to the lake may occur when it rains.
  • Increase the fertility of lake.
  • Encourages eutrophication (algal growth)
  • The growth of algae prevents the light from reaching the base of the lake.
  • This reduce and prevents photosynthesis by aquatic plants.
  • Reduce the oxygen release.
  • Aquatic animals and plants die due to lack of oxygen.
  • Decomposition of dead plants, animals and organic matter by bacteria rapidly.
  • This will increase the dissolved oxygen content.
  • BOD increases the water polluted.
  • This cause the aquatic animals die.

Explain briefly about the acid rain phenomenon and its effect to the environment.



EXPLANATION
  • Occurs when motor vehicles / factory released large amount of nitrogen oxide
  • and sulphur dioxide
  • Nitrogen oxide combine with water vapour in atmosphere to form nitric acid.
  • Sulphur dioxide combine with water vapour in atmosphere to form sulphuric acid.
  • The rain fall as the acid rain.
EFFECT
  • May corrode the building
  • Acidic water causes aquatic animals die
  • Minerals in soil dissolved in water
  • Soil becomes infertile / not suitable for plant to growth
  • Less yield / plant die because of infertile soil
  • The ecological balance of ecosystem distrupt

Explain how ozone depletion occurs. Discuss its effects on human and the environment and suggest the ways to solve this problem.



EXPLANATION 
  • Thinning of ozone layer is due to widespread use of CFC
  • It is used in aerosol, industrial solvents, electronics and in air conditioner
  • Ultraviolet radiation strikes CFC molecule cause chlorine atom to break away
  • Then chlorine atom collides with an ozone molecule and combines with an oxygen atom to form chlorine monoxide and oxygen.
  • Then the free atom of oxygen collides with the chlorine monoxide, the two oxygen atoms form a molecule of oxygen.
  • The chlorine atom is released and free to destroy more ozone molecules.
  • The chlorine produced re-enters the cycle.
  • When the ozone layer becomes thinner, more ultraviolet radiation reaches the Earth.
EFFECTS 
  • Reduction of body's immune system
  • Skin cancer
  • Eye cataract
  • Reduction of rate of plant growth / reducing crop yields
  • Death of plankton / Reduce food supply to aquatic organisms
WAYS TO OVERCOME
  • Reduce / Stop using CFC or chlorine-based products
  • Replace CFC with HCFC
  • Use wrapping paper instead of polysterene boxes

Discuss how forest burning causes disasters to the environment.

  • Releases a lot of carbon dioxide into atmosphere.
  • Carbon dioxide traps heat and causes global warming.
  • Releases heavy smoke which reduces light intensity for photoynthesis.
  • Smoke particles cause health hazards
  • Destroys flora and fauna
  • Lost of herbs for medical puposes
  • Lost of habitat and extinction of flora and fauna

Explain the effect of an increase in carbon dioxide concentration on the ecosystem.

  • Increase in carbon dioxide is due to the burning of fossil fuels in vehicles and excessive cutting down of trees in the forests.
  • Increase in the carbon dioxide traps heat.
  • Mirrored buildings reflect heat
  • which causes a rise in temperature of Earth.
  • This phenomenon is called greenhouse effect.
  • Industries increase the amount of CFCs and methane in atmosphere and cause global warming.
  • It will cause the melting of ice at the poles.
  • The sea level rises
  • which causes low-lying areas to be flooded.
  • It will affect the weather pattern, wind directions and rainfall
  • which will affect the yield of crops and water supply.
  • The land becomes dry and infertile due to drought.

EASY ANSWERING BIOLOGY : MOVEMENT OF SUBSTANCES ACROSS THE PLASMA MEMBRANE

Describe the structure of the plasma membrane based on model proposed by S.J. Singer and G. Nicholas.
  • Plasma protein is composed of phospholipid and protein.
  • Phospholipid molecule has polar head whish is hydrophilic
  • and non-polar tail which is hydrophobic.
  • Phospholipid bilayers are not rigid or static but form a dynamic flexible structure (that is always changing).
  • Various types of protein are partially or wholly embedded in the membrane.
  • There are pore protein and carrier protein.
  • Protein molecules float about in the phospholipid bilayer to form a mosaic pattern that is always changing.
  • Contains cholesterol which links the fatty acids together.
  • Cholesterol helps to stabilize/ strengthen plasma membrane.

State characteristics of the phospholipid bilayer.
  • It consists of hydrophilid heads and hydrophobic tails.
  • The hydrophilic heads are facing the exterior and the hydrophobic tails are facing the interior of the cell.
  • The bilayer is dinamic / not static.

Explain how certain substances pass through the plasma membrane.
  • The phopholipid bilayer is made up of a polar head and non-polar tail.
  • The head of phospholipid is hydrophilic while the tail is hydrophobic.
  • Polar molecules like water can cross the phospholipid layer by osmosis.
  • Small neutral molecules like oxygen / carbon dioxide can cross the lipid layer by simple diffusion.
  • Small lipid-soluble molecules can also cross the lipid layer.
  • Large molecules like glucose and amino acids across the plasma membrane with the help of carrier proteins.
  • Small molecules with charges slightly larger molecules across the membrane using pore protein.

Explain the similarities and differences between facilitated diffusion and active transport.

SIMILARITIES
  • Both ways of transportation need carrier protein
  • to bind with glucose / sodium ion
  • Both transport specific molecules only
  • because carrier protein have specific sites ( to certain molecules)
  • Both processes occur in living cell
  • because they need carrier protein which can change shape to allow substances to move across.
  • Both processes transport substances which cannot pass through the phospholipid layer of cell membrane.
    DIFFERENCES
    Aspect
    Facilitated diffusion
    Active transport
    Movement of molecules Goes down the concentration gradient.


    From a region of higher concentration to a region of lower concentration
    Goes against the concentration gradient.


    From a region of lower concentration to a region of higher concentration
    Molecules can move through Pore proteins & carrier proteins Carrier proteins only
    Energy (ATP) No energy is used.


    Cellular energy is not required to transport glucose.
    Energy is used.


    Cellular energy is required to transport ions.


    Describe how ions are transported in the cell.
    • By active transport- The movement of ions is against the concentration gradient.
    • And it needs energy which is produced by cellular respiration (in the form of ATP molecules).
    • Carrier proteins bind with the ions and change their shape, thus carrying the ions across plasma membrane.

    A chemical substance inhibits the respiration process in the root hair cells of plant. Explain the effect to the transport of mineral ions into the root hair cells.
    • The cell unable to produce energy.
    • Active transport does not occurs.
    • Mineral ions cannot be transported into the cell.

    Explain the movement of water molecules across plasma membrane by osmosis.

    ISOTONIC SOLUTION (5 % sucrose solution)
    • The cell retains its normal shape.
    • The 5% sucrose solution concentration is isotonic to the sap cell of vacuole.
    • Water molecules diffuses into and out the cell at equal rates.
    • There is no net movement of water across the plasma membrane.
    • The protoplasm does not change/ Vacuole does not expand or shrink.
    HYPOTONIC SOLUTION (0.1% sucrose solution)
    • The cells become turgid.
    • The 0.1% sucrose solution concentration is hypotonic to the sap cell of vacuole.
    • Water molecules diffuse into the sap cell of vacuole by osmosis.
    • The vacuole expand & swell up / The plasma membrane pushes against the rigid cell wall / Create turgor pressure
    HYPERTONIC SOLUTION (30% sucrose solution)
    • The cells become shriveled / undergo plasmolysis.
    • The 30% sucrose solution concentration is hypertonic to the sap cell of vacuole.
    • Water molecules diffuses out from the sap cell of vacuole
    • by osmosis.
    • Both the vacuole & cytoplasm shrink / The plasma membrane pull away from the cell wall.

    Explain the method used to preserve fish.
    • Salting - The fish is immersed in the salt solution which is hypertonic to the fish tissues.
    • More water diffuses out from the fish tissues into the salt solution by osmosis.
    • The hypertonic solution causes the fish to be dehydrated.
    • This prevents bacterial growth in the fish tissues.
    • The bacterial cells are also plasmolysed.
    • This prevents decay of the fish.

    Describe the method in preserving vegetables.
    • Vegetables are immersed in vinegar which is acidic.
    • Vinegar diffuses into the vegetables tissues.
    • The vegetables tissues become acidic.
    • The low pH prevents bacterial growth on the tissues.
    • This prevents decay of the vegetables.

    Explain the condition of plant after added with excess fertilizer.
    • Excess fertilizer will cause the soil water to be hypertonic towards the root hair cells.
    • Water from the root hair cells diffuse out to the soil by osmosis.
    • The cells become plasmolysed and this leads to wilting.

    JADIKANLAH AL-QURAN SEBAGAI PENEMAN HIDUP, BUKAN SEKADAR HIASAN

    “Sayang, tengok nih. Cantiknya AlQuran nih. Warna keemasan. Sesuai untuk kita buat hantaran” pekik Jamilah kepada Nabil...

    “Sini pun cantik juga. Warna unggu keemasan. Mana satu kita nak beli nih” balas Nabil.

    Mereka sedang asyik mencari bahan-bahan untuk dibuat hantaran. Tinggal satu lagi yang masih dicari-cari iaitu AlQuran yang bakal dijadikan hantaran.

    “Tapi, yang ni lagi best, ada terjemahan arab” keluh Jamilah.

    “Ala, awak bukan reti pun bahasa arab” jawab Nabil. Tergelak Jamilah. Berbahagia rasanya dapat calon suami seperti Nabil. Prihatin.

    “Apa yang saudara cari tu. Nampak seronok saya lihat” tegur pakcik berbaju putih. Jaluran baju ke bawah menampakkan lagi seri wajah seorang pakcik dalam lingkungan 40-an.

    “Oh, kami cari AlQuran. Nak buat hantaran. Maklumlah, nak bina masjid” sengih Nabil. Jamilah ikut senyum tidak jauh dari situ..

    “Oh. Bagus lah. Adik selalu baca waktu bila?” pakcik menyoal sambil tersenyum.

    “Aa.. aa.. lama dah saya tak baca, pakcik“ teragak-agak Nabil menjawab. Jamilah sudah di sebelah rak yang lain.

    “Kalau gitu, tak perlu lah beli AlQuran kalau sekadar hantaran. Kesian ALQuran. Itu bukan kitab hiasan, dik” tegur pakcik berhemah.

    “Alah, pakcik nih. Kacau daun pulak urusan orang muda. Kami beli ni nak baca la” tiba-tiba Jamilah muncul dengan selamba jawapannya.

    “Oh, baguslah. Kalau gitu beli lah tafsir ArRahman. Ada tafsiran lagi” cadang pakcik. Mukanya nampak seperti orang-orang ahli masjid.

    “Ala, besar lah pakcik. Kami nak pilih nih. Kiut lagi” senyum Jamilah mengangkat bungkusan AlQuran warna unggu keemasan. Saiznya kecil.

    “Jangan lupa baca ya” pakcik dengan selamba sambil meninggalkan pasangan tersebut.

    “Sibuk je la pakcik tu” Jamilah mengomel.

    Nabil kelihatan serba salah. Mungkin ‘terpukul’ dengan kata-kata seorang pakcik yang muncul secara tiba-tiba.

    Hari yang dinantikan sudah tiba. Mereka sudah bersolek. Hari nan indah. Terlalu indah buat pasangan teruna dan dara yang bakal disatukan. Nabil dan Jamilah tidak sabar-sabar menantikan ucapan indah tersebut. Pak imam baru sahaja sampai.

    “Assalamualaikum semua” ucapan salam Pak Imam bergema.

    Nabil bagai hidup semula. Dirinya terkejut. Jantung bagai gugur serta merta. Mungkin tidak percaya apa yang dipandangnya dihadapan. Ahli-ahli keluarga berebut-rebut bersalaman dengan Pak Imam. Mukanya berseri-seri. Janggutnya putih. Jubah putih. Rambutnya ada yang berwarna putih.

    “Inikah pengantin hari ini?” tegur selamba Ustaz Saad.

    “Pak.. Ustaz.. kabar baik, pak... usta.. ustazz..” jawab Nabil mengigil. Jamilah juga terkebil-kebil melihat kelibat orang yang dikenali di kedai buku 2 bulan lalu.

    “Oh, sebelum tu, saya suka mendengar bacaan adik Nabil. Mudah-mudahan kita dapat mengambil manfaat dari bacaan pengantin” cadang Ustaz Saad. Kelihatan orang ramai mengiyakan. Maklumlah, ustaz Saad merupakan antara orang dikenali oleh ahli-ahli sebagai penceramah tetap setiap hari Khamis selepas maghrib.

    Nabil menelan air liur. Baginya inilah saat paling menyeramkan bagi dirinya. Peluh membasahi baju melayu satin berwarna putih.

    “Ss.. su.. surah apa ustaz?” Nabil cuba mengagahkan diri. Jamilah masih melihat dari tepi tirai. Memegang kepalanya. Seperti mengagak benda yang sebaliknya berlaku.

    “Oh, ayat yang mudah ja. Baca 3 ayat Surah ArRa’d” kata ustaz Saad sambil menunjukkan baris giginya yang putih hasil bersugi setiap solat mengikut sunnah nabi. Surah Ar Rad

    Surah Ar Ra'd

    “ Apa benda nih ” detik hati Nabil.

    “ Bismillahirrahmaani rrahim.. ALL..MAA.. RIII..!! ” berlagu Nabil.

    Kelihatan gemuruh satu rumah pengantin perempuan. Ada yang keluar dari rumah menahan gelak. Ada yang mengeluarkan air mata menahan kelucuan. Ada yang menggeleng-geleng kepala. Ibu bapa Jamilah merah padam wajahnya. Jamilah entah ke mana, mungkin berpura-pura ke tandas.

    “ Baru ustaz tahu ada kalimah almari di dalam ALQuran. Adik Nabil, cara bacanya seperti begini : A ’ uzubillahiminnassya itaanirra jim.. Bismillahirrahmanir rahim.. ALIF.. LAMM.. MIMMM... RAA.. ” kedengar suara gemersik Ustaz Sa ’ ad. Orang ramai kelihatan ingin mendengar lebih banyak lagi alunan irama ALQurannya.

    Nabil berasa seperti kilat menyambar kepalanya.

    “ Nabil, kamu jangan merendah-rendahkan kitab petunjuk iaitu AlQuran. Ianya hendaklah dibaca bukan sekadar dijadikan hantaran. Malah lebih malang perlakuan seperti ini seolah-olah menghina ALQuran. Beli ALQuran kemudian menaruh di tempat-tempat tinggi seolah-olah ianya sudah cukup bagi seorang muslim ” tazkirah sudah bermula. Orang ramai memang senang cara penyampaian ustaz Sa ’ ad.

    “ Tinggi mana pun kamu belajar, tiada gunanya kitab yang tidak berubah ini tidak mampu kamu baca. Kitab ini pasti begini rupanya, ayatnya tetap sama, kedudukannya tidak sama. Malah, ketahuilah Allah akan menjaganya sehingga hari kiamat. Nabil, kalau kamu tahu orang-orang yang mengaku kitab AlQuran sebagai kitab petunjuk kemudian diabaikan dia pasti dilaknat oleh AlQuran itu sendiri. Tetapi beruntungnya orang-orangnya memanfaatkan AlQuran setiap hari, membacanya, menghafalnya, mengamalkan menjadikan hati terlalu tenang walapun dia bukannya seorang yang tinggi pelajarannya, kaya hidupnya dan sebagainya.. ” penutup Ustaz Sa ’ ad sudah dikagumi orang terutama yang mengikuti ceramahnya.

    Hari semakin cepat berlalu..

    Nabil sudah melalui hari-hari yang indah. Kitab ALQUran yang menjadi hantaran pertunangan sudah menjadi diari kehidupannya yang aktif setiap hari.

    Pit.. Pit! Jangan lupa datang rumah ustaz malam nih. Kita belajar sama-sama. Jangan lupa bawa isteri sekali ya Nabil. SMS dari ustaz Sa ’ ad tiba. Jamilah senyum disisi suaminya, Nabil. read dis..

    Rasulullah (Sallallahu alaihi wasallam) said: 'When a man dies and his relatives are busy in funeral, there stands an extremely handsome man by his head. When the dead body is shrouded, that man gets in between the shroud and the chest of the deceased.

    Rasulullah (Sallallahu alaihi wasallam) bersabda : 'Bila seseorang lelaki itu mati dan saudaranya sibuk dengan pengebumiannya, berdiri lelaki yang betul-betul kacak di bahagian kepalanya. Bila mayatnya dikapan, lelaki itu berada di antara kain kapan dan si mati.

    Selepas pengebumian, semua orang pulang ke rumah, 2 malaikat Mungkar dan Nakir, datang dalam kubur dan cuba memisahkan lelaki kacak ini supaya mereka boleh menyoal lelaki yang telah meninggal itu seorang diri mengenai ketaatannya kepada Allah. Tapi lelaki kacak itu berkata, Dia adalah temanku, dia adalah kawanku. Aku takkan meninggalkannya seorang diri walau apa pun. Jika kamu ditetapkan untuk menyoal, lakukanlah tugasmu. Aku tidak boleh meninggalkannya sehingga aku dapati dia dimasukkan ke dalam Syurga.'

    Thereafter he turns to his dead companion and says, 'I am the Qur'an, which you used to read, sometimes in a loud voice and sometimes in a low voice. Do not worry. After the interrogation of Munkar and Naker, you will have no grief.'

    Selepas itu dia berpaling pada temannya yang meninggal dan berkata,'Aku adalah Al-Quran, yang mana kamu membacanya, kadang-kadang dengan suara yang nyaring dan kadang-kadang dengan suara yang perlahan. Jangan bimbang. Selepas soal siasat dari Mungkar dan Nakir, kamu tidak akan bersedih.'

    When the interrogation is over, the handsome man arranges for him from Al-Mala'ul A'laa (the angels in Heaven) silk bedding filled with musk.

    Selepas soal siasat selesai, lelaki kacak mengatur untuknya daripada Al-Mala'ul A'laa (malaikat dalam Syurga) tempat tidur dari sutera yang dipenuhi bauan kesturi

    Rasulullah (Sallallahu alaihi wasallam) said: 'On the Day of Judgement, before Allah, no other Intercessor will have a greater status than the Qur'an, neither a Prophet nor an angel.'

    Rasulullah (Sallallahu alaihi wasallam) bersabda :'Di hari pengadilan, di hadapan Allah, tiada syafaat yang lebih baik darjatnya daripada Quran, mahupun dari nabi atau malaikat.
