Identify part f and explain its function. why does the same structure not appear in the cell on the left?

Answer : The structure labelled F is a central vacuole. It performs the following functions in a plant cell -

1. It accumulates the waste product generated by plant cell.

2. It maintains the shape and turgidity of a plant cell.

Since, the animal cells lack a cell wall the turgid pressure maintained by the central vacuole would cause the animal cell to burst. Thus, the animal cells lack a central vacuole as they do not need to maintain a high turgid pressure provided by the vacuole.

Explanation:

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.
