This is another Question taken from RGS, P4 SA2, 2011.

Can someone advise me - this question about tap root system and fibrous root system - which theme in those Science book is relevant for reading and finding the answers? My child said he never study before.

:thankyou:

When we breathe out (flat balloon), the diaphragm (rubber sheet) moves up...
picture 4 is consistent to this.

picture 4 is consistent to this.

pic 1 : diaphragm pushed up means exhale, so balloons should be deflated. (wrong since balloons show inflated)
pic 2 : diaphragm pushed down means inhale, so balloons should be inflated. (wrong since balloons show deflated)
pic 3 : no movement of diaphragm being pushed down, so balloons should not be inflated.
pic 4 : diaphragm pushed up means exhale, so balloons should be deflated. (correct since balloons show deflated)

hope this helps.

hi tayobus,

not too sure if any teacher would teach this but i'm quite sure it does not belong to any topics learnt..

heard from my dd sci teacher, ad-hoc questions that may not have been learnt at all can be tested randomly... most impt is the students' inference skills, able to infer what they have learnt and to apply on these \"new\" questions. this is one of those..

Hi
Sometimes like this question ,you may think that it is not tested.But,when you read the question,you must relate to the topic so that you can find the answer.This is grouped under application questions.
Cheers

yes, agree with charsen…


my dd’s sci teacher says that too…
