Answer:

Structurally, proteins are different from carbohydrates because all proteins contain nitrogen (option C).

Explanation:

The basis of the chemical composition of proteins is carbon, hydrogen, oxygen and nitrogen, so all proteins have nitrogen in their structure. Some proteins also possess phosphorus and sulfur atoms, among others.

Proteins are biomolecules formed by the union of multiple amino acids through carboxyl-amino bonds, called petidic bonds. Their content of nitrogen and other atoms in their structure is what makes them different from carbohydrates.

The other options are not possible because:

  • <em>Only some proteins contain </em><u><em>iron</em></u><em> in their composition.</em>
  • <u><em>Potassium and helium</em></u><em> are not part of the protein structure. </em>

Reika [66]

Answer:

Most plants are auto trophic able to use sunlight as their primary source of energy,in a process called photosynthesis.This process enables them to turn carbon dioxide from the air into food,The carbon and oxygen which they need in order to build up their bodies ultimately comes from this carbon dioxide.

All animals are heterotrophs, which means that they cannot make their own food as plants do. Rather, animals must obtain the energy, carbon, hydrogen, oxygen, nitrogen, and minerals they need by consuming other living things. Animals are also animate, which means that they are capable of movement.
