Answer:
the answer is A. E. coli B
Explanation:
The multiplicity of infection (MOI) refers to the ratio between the numbers of viruses used to infect <em>E. coli</em> cells and the numbers of these <em>E. coli </em>cells. Benzer carried out several experiments in order to define the gene in regard to function. Benzer observed that <em>E. coli </em>strains with point mutations could be classified into two (2) complementary classes regarding coinfection using the restrictive strain as the host. With regard to his experiments, Benzer observed that rII1 and rII2 mutants (rapid lysis mutants) are complementary when they produce progeny after coinfect E. coli K (where neither mutant can lyse the host by itself). The rII group of mutants studied by Benzer does not produce plaques on <em>E. coli</em> K strains that carry phage λ (lysogenic for λ), but they produce plaques on <em>E. coli</em> B strains. This study showed that rIIA and rIIB are different genes and/or cistrons in the rII region.
The trait of the dental gap is present in apes but absent in hominins.

What do you understand by hominins?</h3>
The term "hominin" refers to a group that includes all living humans, all extinct human species, and all of our direct predecessors (including members of the genera Homo, Australopithecus, Paranthropus, and Ardipithecus). Sahelanthropus, Orrorin, and Ardipithecus are the earliest hominins. Many characteristics that set humans apart from other primates were absent in the ancestors of the human lineage. Sahelanthropus tchadensis from the Chad and Orrorin tugenensis from Kenya are the oldest hominins that are currently known. The skull of Sahelanthropus, which dates to between 6 and 7 mya, is mostly complete, and there are also some additional fragmentary bones.

The white adipose serves as the body's chief storage site for lipids.
The body only uses the amount of nutrients and energy it needs to function, any excess after that is what is stored in the adipose tissue. Lipids are stored in the body in different forms such as, triglycerides, fat cells, cell membranes and lipoproteins. Adipose tissue, or fat, is an anatomical term for loose connective tissue composed of adipocytes.
The answer is d. chromosomes help an organism produce usable energy
