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.

lara31 [8.8K]
<h2>Answer:</h2>

To treat the discharge of untreated waste from a type i or type ii marine sanitation device the following steps should be taken into account;

The “Y” valve must be secured to prevent accidental illegal discharge. This can be done by placing a lock or non-reusable seal on the “Y” valve or by taking the handle off the “Y” valve. Only treated sewage from an approved MSD may be discharged directly overboard.
