Q&A - PSLE Science

[Muffins]

tianzhu:

Best wishes

Tianzhu,
You are really one of the best fathers out in this world today. You learn how to solve questions from the books and teach them to your son, YOURSELF, and also help other people, like me, on websites. I have never seen a more commited father than you.

You have also answered so many tough questions on this website (and I'm sure, many, many more websites!), and have given us insight into what tricks there are in some questions and how we can solve them. Your son is lucky to have a father like you!


Hope he does well in PSLE, and hope he gets enough to go to the school of his choice!

BEST WISHES back to you!

Hi Tianzhu,

Can you please tell me what "merging" is? JedaMum was saying "mods please merge into here" before. I don’t really understand what that means.

And what are kiasupoints? I know you’ve got 1000 kiasupoints so far, Tianzhu.

Sorry this is not related to Science, I just really want to know.

StudentABC:

If a question shows the life cycles of a grasshopper and mosquito,


and ask:

Based on the diagrams above, which of the following statements between animals X(mosquito) and Y(grasshopper) is/are true?

A Both the adults do not have wings
B Both the young do not live in water
C Both the adults do not give birth to their young alive
D Both are pests in at least one stage of their life cycles

(1) D only
(2)A and B only
(3)B and C only
(4)C and D only

what should the answer be? Should we use the info given in diagram to derive the answer or use our general knowledge??? Would greatly value help!

and if pollination takes place between 2 different types of flowers, will the flowers develop into fruits????

Please help!!! :?:

my answer will be C and D. its so called commom sense

Hi lalala123, the answer for Q1 is C & D, but sometimes it is not using common sense, as StudentABC has said above. I do not think you can derive that the two animals were pests in their life cycles, as it might be helpful to the environment, but in the diagram, you cannot come to that conclusion easily. Sometimes, you have to remember what you have learnt from textbooks and assessment books.

And for Q2, seldom will nature itself do this, but sometimes, the flower may become a hybrid, but Science syllabus says that the flower will not be pollinated. So, I'm going with the Science books on this one and I would say, the flower would not be pollinated.

Hope I helped!
