Answer:

A: Oil

Explanation:

Chemo synthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or methane as a source of energy.

Bacteria living on the sea floor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide.

Chemo synthetic bacteria are organisms that use inorganic molecules as a source of energy and convert them into organic substances. Chemo synthetic bacteria, unlike plants, obtain their energy from the oxidation.

So Oil is not a possible source of energy for Chemo synthesis.

The vector, which is often a small, circular piece of dna that can exist outside the bacterial chromosome, is known as what?.
kramer

The vector, which is often a small, circular piece of dna that can exist outside the bacterial chromosome, is known as a plasmid.

Bacteria and certain other microscopic species contain plasmids, which are tiny circular DNA molecules. Physically distinct from chromosomal DNA, plasmids multiply on their own. They normally contain only a few genes, including some linked to antibiotic resistance, and they can spread from one cell to another.

Recombinant DNA techniques are used by scientists to splice the genes they want to research into a plasmid. The inserted gene is duplicated along with the plasmid when it duplicates itself. Molecular cloning, the process of creating DNA molecules and introducing them into a host cell, uses plasmid vectors as the means of delivering recombinant DNA into the host cell.

To know more about plasmids, refer to the following link:
