Melting ice sheets increase the volume of water in the oceans and reduce the salinity of water. How would this affect: a) sea animals in polar regions?
b) coastal areas already at sea level?

your answer is B

Explanation:

In the polar regions if the water goes onto shore it would freeze adding to the icy land and giving sea animals an advantage as all the sea animals would be at the to of the sea level giving a better attack on prey. as in Coastal area it would flood the area causing and flood.

the answer for this question would be d. glaciers

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
