irina [24]

Answer:

C. Nucleotides

Explanation:

Nucleic acids are macromolecules which are polymers of nucleotides. There are two types of nucleic acids namely: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Nucleotides are the building blocks of nucleic acids.

A nucleotide is made up of three components:

- A phosphate group

- A five carbon sugar called pentose sugar. In RNA the sugar is ribose sugar and in DNA the sugar is deoxyribose sugar.

- Nitrogenous bases: There are four different types of bases in DNA: adenine, guanine, cytosine and thymine. In RNA thymine is replaced by uracil. Adenine and guanine are purines whereas cytosine, thymine and uracil are pyrimidines.

Nitrogenous base and sugar together are called nucleoside and when phosphate is also attached then it is called nucleotide.

Write the biological mechanism involved in breathing.
barxatty [35]
<span>Good Morning!

The breathing process occurs as follows: Inhalation increases the volume of the lungs, which reduces internal pressure and causes air to enter. Then the exhalation makes the opposite process. Gaseous exchanges occur in the lung alveoli and are responsible for eliminating the gases we do not need and preparing the oxygen to be spread throughout the body.
