Question

which statement best explains why carbon is present in so many kinds of molecules? it can form four covalent bonds it has valence electrons it can become an ion question 2 1 pts which term best describes the role carbon plays in the structure of compounds present in living things? question 3

Explanation:

1. Carbon can form four covalent bonds. This allows it to bond with a wide variety of other atoms (such as hydrogen, oxygen, nitrogen etc.) and form long - chain, branched - chain and ring - shaped molecules, which is why it is present in so many kinds of molecules. Having valence electrons is a general property of atoms and not unique to carbon for explaining its prevalence in molecules. Becoming an ion is not the main reason for carbon's presence in numerous molecules.
2. Carbon plays a fundamental role in the structure of compounds present in living things. It is the backbone of organic molecules like carbohydrates, lipids, proteins and nucleic acids.

Answer:

Question 1: It can form four covalent bonds
Question 2: A fundamental role
