</span>Mitochrondria of the eukaryotic cells.


As many researchers hypothesize that the old single-celled organism or the origin of the complex-celled organisms came from the endosymbiosis of the mitochrondrion organism and the prokaryotic cell. It has been said that mitochondria was an independent organism which then to have been evovled itself after planting itself inside a prokaryotic cell which aided cellular respiration and production of ATP (Adenosine Triphosphate). This then aided the prokaryotic cell to be more sophisticated and caused another change from having without a true nucleus to a eukaryotic cell with a nucleus and embedded DNA. </span>

The map shows the allele frequency of sickled hemoglobin (HbS) and malaria endemicity in Africa.
ikadub [295]

When an area is malaria-free, the HbS allele frequency is between 0 and 2.02. Thus, option "A" is correct.

<h3>How, explain your answer briefly?</h3>

In the two maps that show the allele frequency of sickle haemoglobin (HbS) and malaria endemicity in Africa, it can be seen that in the regions with no malarial outbreak or malaria-free areas coincide with the grey to lighter shades of red in the heat map of the allele frequency of HbS. The colour coding in the heat map for the allele frequency tells us that the frequencies range from 0 to 2.02 in the malaria-free areas.

Hence the answer is A)When an area is malaria-free, the HbS allele frequency is between 0 and 2.02.

What is the purpose of MITOSIS?
Mumz [18]

Answer:

D

Explanation:

A: to create sex cells of reproduction.

This is the purpose of meiosis: a cell division process. It creates gametes, or sperm and eggs.

B. to provide the cells with food

This would be eating for animals, or photosynthesis for plants. When animals eat, it provides their cells with food. When plants photosynthesize, they create their own food in the form of glucose.

C. To give the cell energy

This would be cellular respiration. It turns food and glucose into usable energy called ATP.

D.

This is the correct choice. Mitosis is cell division, which means it creates new cells. This allows organisms to grow and repair.
