Hypothesize why parts of a plant, such as the leaves, are green, but other parts, such as the roots, are not. use scientific reasoning to support your hypothesis.

Leaves are green because they contain a green pigment.

In the parlance of science, a hypothesis is a tentative explanation which must be testable.

In this case, i have hypothesized that the reason for the green color of leaves is the presence of a green pigment.

I must now subject the leaves, root and back of the tree to laboratory experiments to see if this pigment can only be extracted from the leaves.

If indeed, this pigment can only be extracted from plant leaves then the hypothesis is found to be true.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
