Compare the properties of the parent and daughter cells in mitosis and meiosis and explain the reason for any differences.

katrin [286]

Mitosis - 48 chromosomes (diploid cells)
Meiosis - 24 chromosomes (haploid cells)

Diploid cells. Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.</span>

Answer:

Obligate mutualism.

Explanation:

Obligate mutualism: It is defined as each organisms are obligated to each other, they rely on one another, means one species cannot survive without the other species. It may involve the interchange of resources, for example food, shelter, and nutrients or may interchange services like transportation, and protection.

Termites are mutualistic related to protozoa which lives inside the insects gut. Termite gets benefits from the bacterial symbiont ability which is present in the protozoa to digest the cellulose. The termites do not have this ability to do this, without the help of protozoa. They are not able to use their energy from the food which is wood, cellulose comes from wood it chews.

So, termites are mutualistic related to protozoans and showing obligate mutualism.
