Answer:

Answer:

(Choice B) 5 homologous pairs of chromosomes comprising a total of 20 chromatids.

Explanation:

Homologous chromosome are those two chromosomes which have same gene but different in shape and appearance.

Chromatids are the identical copies of chromosome. Single chromosome splits into double number of chromatids. In 5 pairs, 10 chromosomes are present so 10 chromosomes splits into 20 chromatids.

Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each cell?

What would happen to a cell if its mitochondria stopped working? And why would it happen!?

B. cells can be influenced by genetic factors. C. cells always repair damaged genes immediately. D. a person cannot survive if even one cell becomes damaged.

Answers

Answer: B cells can be influenced by genetic factors

Explanation: Daren has sickle cell disease. Sickle cell disorder is a kind of disease that affects the hemoglobin in the red blood cells. Hemoglobin, is a molecule in red blood cells that delivers oxygen to cells throughout the body. People with Sickle cell disorder have hemoglobin molecules called hemoglobin S, which distort the shape of the red blood cells. A normal red blood cell has a disc shape but people with sickle cell like Daren have their red blood cells and distorted into a sickle, or crescent, shape
