Answer 1

Answer:

A. Carbon

Explanation:

Carbon is one of the most important elements for the structure of living things. It is responsible for 19% of the body composition of animals, behind only oxygen, which contributes 61%. The head is one of the main elements that make up the tissues and organs of animals.

Carbon has a special property: it can make four different chemical bonds. This means that, in addition to being able to bond with atoms of other elements such as hydrogen, oxygen, nitrogen, sulfur and phosphorus, carbon can also bond in different ways with other carbon atoms.

The result is the formation of thousands of carbon compounds that are present in nature, rocks, minerals, products made in industries, plastics, smoke, oil, plants, animals and within our own bodies.
