It is carbon dioxide.Rice kiasu:
Hi,science paper bklt A Q5. rate of photosynthesis is reduced bcause lack of ___.
Is it carbon dioxide or water?My Ds put water.

You mean the MCQ one ? Its the same . Gravity dont change .[/quote]
Even when height is different?[/quote]
I thought it is gravitational energy that will change when the height is different? I thought gravitational force depend on mass? :scratchhead:[/quote]
That was how my DD explained to me too when I thot height affects the gavity lvl.... -
dagong99:
My ds ans is more exposed surface area & air can flow through the gaps b/w the plates to increase the rate of evaporation, ok?
Can check with cher . I'm not very sure
But I'm sure SEAB will accept lots of answers , so I think you are quite safe .

Yeahup . Gravity only changes when masses , distance . (according to my sci journal)[/quote]
Crap 5 marks gone- :stupid: -

Is there any more questions in the booklet A that need to be discussed?.. I forgot all of the questions.. Haizzz.. Only question 1

I just want to clarify with all of you, is it true that there is more weightage on English and Chinese? My friends and their mummies say that English+Chinese=200%, Science is 50% and Maths is 50% as well…
Oh yes, I want to ask about question: ‘Which set-up should he use as a control’
What did you put? -
On the question about the force of gravity, my view as follows.
The force of gravity can change and it decreases with altitude. When the ball is kicked, there will be a change in altitude, resulting in a change in this gravitational force. -
