Cells are surrounded by water, and cells themselves are about 70-95% water. as a result,
a. our ces freeze when we get cold
b. the temperature of living things tends to change relatively quickly
c. a variety of nutrient molecules are readiy available as dissolved solutes
b. waste products produced by cell metabolism accumulate in our cells

The correct answer is c. a variety of nutrient molecules are readiy available as dissolved solutes.

Explanation:

There are several molecules that act as nutrients, that can dissolve in water. Mostly inorganic compounds like salts can dissolve in water, resulting in ions that can go through the membrane easier. The temperature of living things actually is more stable because of the water in them.

the answer is c. altitude. hope this ! #brainiac
