<span>b. t cells and memory cells
</span>
These immune cells produce a proper response chemical to combat the microbes. The initial exposure of the body to an infectious agent e.g. through a vaccine, triggers an immune response most of which rapidly diminishes after the vaccination.  However some cells of the immune system called lymphocytes remain with a memory of that pathogen.<span>As a result, if the same pathogen infects a vaccinated person, the memory cells remember and recognize it . </span>

agasfer [191]

Answer:

Explanation:

Spongy bone is also called cancellous or trabecular bone. It is found in the long bones and it is surrounded by compact bone. ... Trabeculae are spaces created in the tissue by thin areas of osteoblast cells. As a result, trabecular bone has about 10 times the surface area of compact bone.

A gene exists in two alleles, which we will call B and b. The gene is 1123 bp in length, and the B and b alleles exhibit single
Hitman42 [59]

Answer:

The below options will complete the question

Select one:

a. Gap repair synthesis

b. Mismatch repair

c. Direct repair

d. Nucleotide excision repair

Our answer is surely A.

a. Gap repair synthesis

Explanation:

Alleles of gene B differ by 6 bps and are seeming close to each other among the 1123 bp within the particular gene, favouring the gap repair synthesis.

In the gap repair synthesis, a double stranded break is formed at a homologous chromosome with a small part of the gene or the 6 bps of the recessive allele

being digested away.

Strand invasion and a D-loop formation is followed by the new region being occupied by the dominant B allele to yielding dominant B allele in both chromosomes.

The gap repair synthesis allows the 6bps to be converted to the dominant B from the recessive b when in proximity/being close together.
