Q25 is D ya..
ReplyDeletewhy 8 the answer is not D,ANSWER A,C AND D ARE CORRECT,ISN
DeleteT???
D is the only logical answer
Deletewhy is 1 c ? why not d ???
ReplyDeletewell, if you check the f4 textbook, the only organelle that has 'found only in animal cells' description is lysosome
Deleteplant has no centrioles
DeleteThat's not lysosome. Its lysozyme which is an enzyme
Deleteand why is 9 c?
ReplyDeleteFiest question should be D …
ReplyDeleteQ44 isn't D ? It didn't mention about fertilisation occur , just release two secondary oocyte
ReplyDelete"most likely" to be produced
Deletelook at the question carefully,the question say what type of twins are most likely to be produced~so i think is c :)
DeleteStill, I think it's like - based on the statement. So my answer is D. hurmm
Deleteisit 22 should be A?
ReplyDeleteI got A too
DeleteA right?
Deletebecuz got a fish at Y,fish absorb oxygen in Y,cause low conc. of oxygen?
Deletethe fish in Y is providing CO2 for the plants to photosynthesis, otherwise how can it produce oxygen? so, i feel is A...
DeleteI 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?
Deleteshould be A ..the plant will use the CO2 to carry out photosynthesis..so the oxygen should be high..right?
Deletedont forget plant also carry out respiration. so it uses up oxygen as well.
Deletecan we rear fish in a test tube in the first place? LOL
Deletebut 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??
Delete29 confirm is A.
ReplyDelete25 is D.
ReplyDeleteQ22 A?????
ReplyDeleteQ29 should be A
29 is A right?
ReplyDelete29 is A
ReplyDeleteIsn't no.9 is c???
ReplyDeleteno 9 is D bcoz it says organelle X damaged. not ribosom.
DeleteOrganelle X is the rough er.. the function of rough er is to transport protein synthesised by the ribosome... the answer should be D
DeleteIs 25 A??
ReplyDeleteOr D
ReplyDelete25 is D right? why A ? :(
ReplyDelete29 is A haa? why D aish.
ReplyDeleteLol the Answers got major problem. Q9 is D, Organelle R is RER (transport protein). Q22 is A , Q25 is D.
ReplyDeletebrilliant!i got the same anwers as you
Deleteyay! me too!! god.. are u sure?? y soo many answers are there? which 1 is correct? :/
DeleteThis comment has been removed by the author.
Delete29 must be A right? Anyone?
ReplyDeleteLow 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?
many mistake for the answer.
ReplyDeleteNo.9 should be D. It mention RER not ribosome
ReplyDelete42 why not D????
ReplyDeleteWhy is 23 not A? ._.
ReplyDeletethin moist layer is correct. .but only moist could slow down the diffusion
DeleteWow. Thats confusing -_-
DeleteQ: Which characteristic refers to the part shown in the diagram?
DeleteI 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
for paper 3,q 2,what are your exp?
ReplyDeleteIt's the cellophane thing. But I put sticky tape instead of cellophane tape ugh. Anyone else?
DeleteI put sticky tape too
Delete8) should be a and d ... most reference book answer ...
ReplyDeletecan it be methylene blue solution?
ReplyDeleteMr Sai Mun,
ReplyDeletePls recheck your answers, I think that there are many disputes
mr simon pls pls pls REUPLOAD the actual answer. your corrections is confusing ppl. pls put up a new picture post with new answer thank you.
ReplyDeleteCan i know how,many did urs guys get???wanna see how is the,graph thor...comment ur score ty...
ReplyDelete45/50, I guess that's okay, but when I think about my Exp p3 Q2.... :/
DeleteI didn't even know what exp that was...
me too. i have no idea about the experiment Q2. but my friend is so lucky. she read that experiment before seat for the paper 3 just now.
Deletequestion 2 u use cellophane tape
Delete22 is a or b? anyone?
ReplyDeleteMy ans is A..
Delete49 is c right?? coz i think blood group is soo not related :/
ReplyDeletewhy c? its d. u cannot change ur blood group right?
Deletewtf. i see some of these answers are wrong. like seriously mr sai mun!! pls stop confusing other people. the answer for 29 is A. i'm pretty sure there's a lot of question that you give the wrong answer. you are obviously not a ' true' tcer, pls take this post down and CHECK YOURSELF, sir! #nodisrespect #imjustsayin
ReplyDeleteSTFU! Don't be so rude!! At least SOMEONE spent some time to mark the answers for all of us! I agree there is some questions with wrong answers, but still, did you have to be so hardcore about this?

ReplyDeleteHOLD UP. number 22 is B??? Say what? it's A kan? please say it's actually A
ReplyDeleteSir, 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.
ReplyDelete44 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.
ReplyDelete9 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 .
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"
DeleteA 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"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

ReplyDeleteHi, can u please check the answers all over again? Just to ensure the answers are all correct.. thanks alot. :)
ReplyDeletebut wait. 25 is A right? i'm quite sure it is A.
ReplyDeleteanswers updated. dun kan cheong too much ah
ReplyDeleteMr Sai Mun what about question 22? is the answer is B??
DeleteWhat about 8? All three are saturated fat except corn oil
ReplyDeleteyeah, 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
Deletei agree with him. the state of the fat. margerine usually made from plant butter from animal fats.
DeleteShouldn'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...
ReplyDeleteIleum secretes enzyme too.. erepsin maltase sucrase lactase
DeleteWell , 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 .
ReplyDelete40/50 urgghh... Worried liao...
ReplyDeleteThank you for updating with the correct answers.
ReplyDeleteHey guys, paper3 question 2..what if I use filter paper replace the cellophane tape ?
ReplyDeletecannot 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.
DeleteFor question 8 why the answer is A ? I thought coconut oil contain more saturated fat han butter and margerine.
ReplyDeleteFor question 22 can you kindly please recheck the answer? I had chosen A for an answer, am wonderig if the answer is correct?
ReplyDeleteHow many wrong that can make me get A for bio?
ReplyDeleteHow many max wrong that i can get A?
ReplyDeleteI 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
ReplyDelete49/50 if 22 is A :(
ReplyDeleteBut 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.
ReplyDeleteya I agree with you :)
ReplyDeletecomments 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.
ReplyDeletewhy all answer wrong. so noob
ReplyDeleteThe 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
ReplyDeletewhat is average mark to get A- bio
ReplyDeletegot 42/50 for bio chem n 44 for phy :D
ReplyDeleteMay I ask a question?
ReplyDeleteThe 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.
wow very famous mr sai mun
ReplyDeleteoh now i see ur blog focus on student study tips!
add oil ^^ hope more students benefit from it
MY-Emily
mr saimun can get EST answers please? :(
ReplyDeletei got 43/50... im quiet happy bec i nver got 30 above i always got 27 and below..;)
ReplyDeleteHello 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 ?? :(
ReplyDeleteI got 34/50..so sad
