Answer:
This help them to maintain internal homeostasis in hot climates by retaining water .
Explanation:
Homeostasis is maintaining balance within a system, as you can see this in cells. This in them conserve as much water as possible, they do this by converting their waste to a solid, since it doesn't require water to excrete. This helps them to maintain internal homeostasis in hot climates since the presence of water allows them to cool easily. In case of the homeostasis the movement of particles takes place against the concentration gradient.
