Answer:c. Steroids/cholesterols and phospholipids
Explanation:
The cell membrane structure exhibit a fluid mosaic model due to the presence of two types of membrane lipids these are phospholipids and sterols like steroids/cholesterols.
A phospholipid is a kind of lipid that is made up of glycerol, two fatty acids in tail and a head group associated with the head group. The biological membrane forms two layers of phospholipids with their tails that points inwards and the arrangement is called as the phospholipid bilayer.
The cholesterol is the another membrane lipid in the cell membrane. It is composed of fused carbon rings present along the side of phospholipids.
Answer:
C) Initially mutation will be the only source of variation in the population
Explanation:
In this experiment, mutation will be the only source of variation in the population.
Therefore, natural selection cannot begin operating immediately on the population because there was no initial variation.
Also initial differences in the population will not be as a result of sexual selection.
Finally, mutation is a random process. Despite the two populations being identical they will accumulate different mutations. Therefore after 100 generations the two populations will not be genetically identical.
