<h3>ANSWER: </h3>

(D) All of the above.

<h3>EXPLANATION: </h3>

Resistance to pathogens may be developed when the pathogen comes in contact with the body either voluntarily (vaccinations) or involuntarily (contracting a disease). Resistance can also be developed through the B and T cells, it involves the cells binding an antibody to the pathogen so they cannot enter a healthy cell.

The answer is d (All of the Above). While vaccination is a way of introducing attenuated pathogens into the body to invoke an immune response and memory, ocassionaly, an infection of disease can also invoke immune response and memory after healing. This immune memory is mainly through memory T and B cells.

If meiosis failed to occur in both male and female worms the zygote nucleons would resemble diagram
den301095 [7]

Tetraploidy will occur.

<h3><u>Explanation</u>:</h3>

The process of sexual reproduction is very necessary to maintain the genetic setup of the species over the races.

The normal chromosome content of a cell is called diploid state of cell. Its represented by the expression 2n. The cell division that takes place before the gamete formation is called meiosis. This cell division makes the chromosome number of the cells halved. So haploid cells are produced. Its represented by n.

Now as the gametes fuse, both the n becomes 2n and diploid state is regained.

But if the meiosis don't occur in the gametes, the gametes will remain 2n. So after fertilization, it becomes 4n. This state is called tetraploidy.
