Ascientist is examining the role of an element found in fats and carbohydrates of living things. this element makes up 65% of human body mass. which statement describes the element he is studying? he is studying oxygen, which can also be found in proteins. he is studying oxygen, which is the most abundant element in the atmosphere. he is studying nitrogen, which can also be found in proteins. he is studying nitrogen, which is the most abundant element in the atmosphere.

The right answer is He is studying oxygen, which can also be found in proteins.

Carbon atoms could also be a right answer if there was a statement...

Sugars, composed only of carbon atoms, hydrogen, and oxygen, are the simplest energetic nutrients.  Example to (C6H12O6): If we look at the chemical formula for glucose, we can see that the proportion Hydrogen / Oxygen corresponds to that of water (H2O)

Lipids also consist of carbon atoms (C), hydrogen (H) and oxygen (O), but fatty acids are molecules that are low in oxygen.   Example: Linoleic acid C18H32O2

the bullets go in this order.

4, 1, 3, 5, 2

the right answer is a. skin cells forming from sunlight.
