Answer:
nucleic acids and phospholipids
Explanation:
- Phosphorous is required to make two essential molecules in the body- the nuclei acid and the phospholipids.
- The nucleic acid contains carbon, hydrogen, oxygen, nitrogen, and phosphorus and is organic compounds that codes for the genetic information in an organism. There are two types of nucleic acid- ribonucleic acids and deoxyribonucleic acids, i.e RNA and DNA respectively. Both of them sugar-phosphate backbone and therefore, phosphorous is essential for the synthesis of nucleic acids in the body.
- Phospholipids make up the cell membrane and thus, phosphorous is also essential for their synthesis.
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution.
A mutation is a change in trait. For example people who are lactose intolerant are normal, but people that can can drink milk without a problem have mutated. Hopefully this makes sense and helped.
