<span>The ability of water to hold more heat than land keeps the temperature on earth moderate
If the oceans didn't hold large amounts of heat, then the Earth would probably overheat which would cause many problems for all life forms.</span>
B is the answer
That is correct
using seeds from the same source.

giving the control and experimental groups the same volume of water.
keeping the light the same for the experimental and control groups.
measuring plant height the same way and at the same time for both groups.
Yeah pretty sure because everything looks right
