    1. well, if you check the f4 textbook, the only organelle that has 'found only in animal cells' description is lysosome

      Delete
    2. plant has no centrioles

      Delete
    3. That's not lysosome. Its lysozyme which is an enzyme

      Delete
  3. Fiest question should be D …

    ReplyDelete
  4. Q44 isn't D ? It didn't mention about fertilisation occur , just release two secondary oocyte

    ReplyDelete
    Replies
    1. "most likely" to be produced

      Delete
    2. look at the question carefully,the question say what type of twins are most likely to be produced~so i think is c :)

      Delete
    3. Still, I think it's like - based on the statement. So my answer is D. hurmm

  5. isit 22 should be A?

    1. I got A too

      Delete
    2. becuz got a fish at Y,fish absorb oxygen in Y,cause low conc. of oxygen?

      Delete
    3. the fish in Y is providing CO2 for the plants to photosynthesis, otherwise how can it produce oxygen? so, i feel is A...

      Delete
    4. I put B for no 22. What i had in my mind is the fish pruses up oxygen n releases carbon dioxide. The plany uses carbon dioxide n releases oxygen. So the oxygen level is low. Isnt it correct? What do u guys think?

      Delete
    5. should be A ..the plant will use the CO2 to carry out photosynthesis..so the oxygen should be high..right?

      Delete
    6. dont forget plant also carry out respiration. so it uses up oxygen as well.

      Delete
    7. can we rear fish in a test tube in the first place? LOL

      Delete
    8. but the rate of respiration of plant is lower than photosynthesis when there has light intensity and presence of CO2..which expelled by the fish...hence I think the answer should be A? dunno??

      Delete
  6. 29 confirm is A.

    ReplyDelete
  7. Q22 A?????
    Q29 should be A

    ReplyDelete
  8. 29 is A right?

    ReplyDelete
  9. Replies
    1. no 9 is D bcoz it says organelle X damaged. not ribosom.

      Delete
    2. Organelle X is the rough er.. the function of rough er is to transport protein synthesised by the ribosome... the answer should be D

      Delete
  10. 25 is D right? why A ? :(

    ReplyDelete
  11. 29 is A haa? why D aish.

    ReplyDelete
  12. Lol the Answers got major problem. Q9 is D, Organelle R is RER (transport protein). Q22 is A , Q25 is D.

  13. 29 must be A right? Anyone?
    Low concentration of oxygen (polluted area) = time taken for decolourise is fast/quick
    High concentration of oxygen (clean area) = time taken for decolourise is slow/long
    I know this from the B.O.D experiment. So the answer should be A or am I still wrong?

    ReplyDelete
  14. many mistake for the answer.

    ReplyDelete
  15. No.9 should be D. It mention RER not ribosome

    ReplyDelete
  16. 42 why not D????

    ReplyDelete
  17. Why is 23 not A? ._.

    1. thin moist layer is correct. .but only moist could slow down the diffusion

      Delete
    2. Wow. Thats confusing -_-

      Delete
    3. Q: Which characteristic refers to the part shown in the diagram?

      I think, since it's based on the diagram, you can't tell if the surface is moist, or thin walls, or more permeable to O2. So, the ans is C

      Delete
  18. for paper 3,q 2,what are your exp?

  29. HOLD UP. number 22 is B??? Say what? it's A kan? please say it's actually A

    ReplyDelete
  30. Sir, these answers aren't directly from you, so I can't blame you that much, but since you are posting the answers you should have double-checked the credibility of the source beforehand. With all due respect, kindly repost with the correct answers. Thank you.

    ReplyDelete
  31. 44 is D as the woman released two secondary oocyte,yes but during a menstrual cycle meaning implantation of the embryo will not occur.Thus,there will be no formation of twins.

    9 should be D as it stated "diagram 1 shows organelle X with attached ribosomes" organelle X refers to the rough ER.ribosomes function to be the site of protein synthesis and the RER is to transport the protein synthesis.Thus,the answer is protein cannot be transported if RER is damage,D. Ribosomes are still suspended around the cell but RER will not be able to transport it to Golgi if it is damaged .

    ReplyDelete
    Replies
    1. Are you sure 44 is D? The question is confuse, I choose D also ,but my friends mostly choose C , the comment above said the question asked for "most likely"

      Delete
    2. A menstrual cycle is referring to the whole thing and not just the menstruation phase. There could be chances for implantation, but it's not really stated in the question.

      Delete
    3. "a menstrual cycle" means that the whole cycle..not menstruation..its obviously stated that "most likely produced",,then there is no doubt that the answer is c (^^)v

    1. Mr Sai Mun what about question 22? is the answer is B??

      Delete
  36. What about 8? All three are saturated fat except corn oil

    ReplyDelete
    Replies
    1. yeah, that was a stupid question i think. Coconut, margarine and butter ALL have saturated fat. But i think the quest was referring to state at room temperature. Since the rest are oils, butter should be the answer. But its not a good question IMO

      Delete
    2. i agree with him. the state of the fat. margerine usually made from plant butter from animal fats.

      Delete
  37. Shouldn't question number 2 be A as one part of ileum is removed...ileum only involve in absorption and glucose is the substance that is absorbed...

    ReplyDelete
    Replies
    1. Ileum secretes enzyme too.. erepsin maltase sucrase lactase

      Delete
  38. Well , I am afraid that I cant score even a A in Biology ,SInce My P3 question 2 17 marks is gone . I do it with methylene blue solution and I get 0 mark on that .

    ReplyDelete
  39. 40/50 urgghh... Worried liao...

    ReplyDelete
  40. Thank you for updating with the correct answers.

  41. Hey guys, paper3 question 2..what if I use filter paper replace the cellophane tape ?

    ReplyDelete
    Replies
    1. cannot cause some of the item for the experiment is microscope to observe the dust or whatsoever. using filter paper 1) cannot capture most of the dust and the dust may flew off. You cannot observe it under the microspoce.Plus, some of the dust are not black in colour.

      Delete
  42. For question 8 why the answer is A ? I thought coconut oil contain more saturated fat han butter and margerine.

    ReplyDelete
  43. For question 22 can you kindly please recheck the answer? I had chosen A for an answer, am wonderig if the answer is correct?

    ReplyDelete
  44. How many wrong that can make me get A for bio?

    ReplyDelete
  45. How many max wrong that i can get A?

    ReplyDelete
  46. I think the answe for question 22 sould be A....because when the light intensity increases,the rate of photosynthesis will increases too...and I don't think the fish will used up a lot of oxgen..since it produces co2 too..hence amount of O2 should be high

    ReplyDelete
  47. 49/50 if 22 is A :(

    ReplyDelete
  48. But 22 is obviously A because the present of lights allow the photolysis of water to form oxygen gas in plant. The concentrationbofboxygen should be high and CO2 should be low.

    ReplyDelete
  49. ya I agree with you :)

    ReplyDelete
  50. comments for number 39. why the answer is not C. can auxin can decreased or will continue produce. Please help explain me because the question stated after few days.

    ReplyDelete
  51. why all answer wrong. so noob

    ReplyDelete
  52. The concentration of auxine is lower at the root and higher at the shoot. The higher the concentration of auxine, the more the shoot grows towards sunlight. So D makes sense. TeeHee

    ReplyDelete
  53. what is average mark to get A- bio

    ReplyDelete
  54. got 42/50 for bio chem n 44 for phy :D

    ReplyDelete
  55. May I ask a question?
    The paper 3 section B, i wrote
    Problem statement : Do locations P,Q and R have the same level of air pollution?
    Hypothesis : Locations P, Q and R have different level of air pollution. Different places have different Air Pollution Index(API).

    Is this acceptable? :( I am really worried.

  56. wow very famous mr sai mun

  59. Hello mr sai mun...can i ask , paper 3 experiment if use methylene blue solution confirm wrong ? Because as for me, i think my procedure is something like collect dust into three different test tube and then shake it in blue methylene solution (as a dissolved oxygen) logic ? So totally 0 markss ?? :(
