Cholesterol in Cell membrane strengthens and helps to maintain the fluid nature of a cell regardless of temperature
<u>Explanation:</u>
All organisms are made up of one or more cells. Each cell is protected or differentiated by a covering called as the cell membrane. Phospholipids are the basic structure of the cell membrane. Cholesterol prevents the loss of fluid from phospholipids.
Cell membrane has a lipid layer and cholesterol which is placed between the phospholipids to maintain the fluid nature of the cell under different temperature. Cholesterol prevents the cell from solidifying and helps maintain the fluid. Cholesterol actually acts as a buffer between different temperatures.
Answer:
A phospholipid contains a phosphate group, two alcohols, and one or two fatty acid chains
Explanation:
Because natural selection is caused so that an organism can adapt and better survive their environment. They are involved in the formation of fossils because organisms that die are buried in sediment and become fossils.
