The correct answer is the last statement.
If the regulatory serine is mutated to alanine, then acetyl-CoA carboxylase will get activated spontaneously and will produce malonyl-CoA. The increased concentrations of malonyl-CoA will obstruct the oxidation of fatty acids by preventing the entry of fatty acids into the mitochondria.
It is because the AMP-activated protein kinase phosphorylates the serine residues of acetyl-CoA carboxylase to inactivate it. If a mutation occurs in such residues, then the AMPL cannot phosphorylate acetyl-CoA carboxylase and this enzyme will get activated spontaneously.
In such a situation, there will be more than sufficient production of malonyl-CoA, which will inhibit the admittance of more fatty acid getting inside the mitochondria; this will indirectly prevent the oxidation of fatty acids.
Telomerase activity is controlled during development and is extremely low in somatic (body) cells, virtually undetectable. These somatic cells age because they do not frequently use telomerase.
- Telomeres are repetitive sections at the very ends of chromosomes that are present in a variety of eukaryotic species, including humans and unicellular protists.
- Each round of DNA replication wears down a little portion of the telomeres, which serve as caps to safeguard the interior chromosomal regions.
- Most somatic (body) cells do not typically have telomerase activity, but certain adult stem cells and germ cells—the cells that produce sperm and eggs—have.
- Adult germ cells, tumor cells, and fetal tissues all contain telomerase. Telomerase activity is controlled during development and is extremely low in somatic (body) cells, virtually undetectable. These somatic cells age because they do not frequently use telomerase.

Answer:
Explanation:
The things that are changing in an experiment are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled
