Amacromolecule that contains carbon hydrogen oxygen and nitrogen which is used for the body for growth and

Proteins.

Explanation:

Biomolecules are the macromolecules and the organic compounds required for the growth of the living organism. Four important biomolecules are carbohydrates, proteins, lipids and proteins.

Proteins are the polymers of the amino acids linked together through the peptide bond. The proteins are made up of carbon, hydrogen, oxygen and nitrogen. Proteins are the main building block of the body and required for the proper growth of the living organism.

Thus, the answer is proteins.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
