What happens to the water supply when icecaps and glaciers are formed? Water increases. Water decreases Water changes to gas. Water remains the same.

Water volume remains the same.

Explanation:

Ice formation is a phase change from liquid to solid.  The ice is less dense so its volume gets larger.  Warm it up, melt the ice and it will return to the same volume it had as a liquid.

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.
