[quote=\"stickyz\"]Anyone can still remember the gravity question? Whats your answer? :scratchhead:


help pls!!

You mean the MCQ one ? Its the same . Gravity dont change .

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:

[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?

Oh, probably
1) To prevent overcrowding.
2) To ensure that Plant B grows and ensure the continuity of its kind even when the conditions of some places are not suitable for Plant B growth.
