when changes in a protein appear to accumulate at a constant rate over time is called option (c) i.e, Molecular clock.

<h3>What does molecular clock mean?</h3>

The term "molecular clock" refers to a method that estimates the time in prehistory when two or more life forms diverged by analyzing the mutation rate of biomolecules. Typically, nucleotide sequences for DNA, RNA, or amino acid sequences for proteins serve as the biomolecular data for these calculations.

Hedges, a biology professor at Penn State, claims that the molecular clock counts the mutations that accumulate through time in the gene sequences of various species rather than counting seconds, minutes, and hours.

Mutation and recombination, the two fundamental biological processes that give rise to all heritable variations, are the foundation of molecular clocks. Mutations are modifications to the genetic code of DNA, for as when the nucleotide Guanine (G) turns to Thymine (T).

Cholesterol has a much higher profile than the other lipids because of its association with heart disease. Despite its lethal re

yaroslaw [1]

Answer and Explanation:

The mechanism of action of statins begins with the inhibition of a protein called HMG-CoA reductase, allowing its substrate to accumulate in the body and promote cholesterol reduction. At that moment, a transporter called OATP (Organic Anion Transporting Polypeptides) takes statins to the epatic tissue where they will be transformed and metabolized until they are eliminated through bile. This elimination is influenced by the P-glycoprotein, which is the main cause of the efflix presented by the bili. This process can get help from other molecules like some protease inhibitors, digoxin and cyclosporine.

When gas molecules begin to clump together in molecular cloud they increase the

Schach [20]

At the center of the cloud, more weight of the gas molecules are present.

The mass or weight at the center of the cloud increases when the gas molecules group together in a molecular cloud because more gas molecules are present at the center which combines with each other leads to heavier weight of gas molecules. The combination of gas molecules make the center of the molecular cloud denser as compared to other parts of the cloud so we can conclude that increase in mass occur at the center of the cloud.
