Which element is found in nucleic acids but not in proteins?
carbon
hydrogen
nitrogen
phosphorus

phosphorus is found in nucleic acids but not in proteins

Explanation:

Carbon, hydrogen and oxygen (C, H, O) participate in the composition of organic compounds such as carbohydrates, lipids, proteins and nucleic acids.

Nucleic acids are formed by: carbon (C), hydrogen (H), oxygen (O), nitrogen (N) and phosphorus (P).

Proteins are biomolecules. 5 elements are  found in most proteins: carbon (53%), hydrogen (7%), oxygen (23%), nitrogen (16%) and sulfur (1%). Nitrogen differentiates proteins from fats and carbohydrates.

Then we can see that phosphorus is found in nucleic acids but not in proteins

compost can be added to topsoil as a:

pesticide

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
