Three ways in which organisms use carbohydrates

Animals, plants, fungi and bacteria use carbohydrates in varying ways. For plants, carbohydrates form a large part of their structure in the form of cellulose. Animals use carbohydrates primarily for energy, such as starch, glucose and other sugars. Bacteria use carbohydrates for both structure and energy. 

In the given case, the good student will say yes.

Explanation:

The molecules containing hydrophilic phosphate heads and hydrophobic lipid tails are known as phospholipids. These forms of lipids are found in the cellular membranes and perform an important activity by protecting and covering the internal components of the cell.  

A reply by a good student will be yes for the question asked by Dr. Haxton, as fats and water are not compatible with each other. The nonpolar molecules like fats do not get mixed with water, and thus, possesses the tendency to travel within the particles that get covered by proteins and phospholipids, which are polar in nature .
