The best answer is C
The process by which a cell divides is called mitosis. It results in two daughter cells that are genetically identical to each other and to the original cell.
Multicellular organisms, depend on mitosis for growth and repair. Organisms repair some of their tissues using mitosis to regenerate new cells. Not all cells undergo mitosis at the same rate. In man, brain cells are much more difficult to regenerate than cheek cells which are constantly being replaced.
The basic unit of life is a cell. Have a great day!
B cells mature in the bone marrow, which is at the core of most bones It recognises invaders by the shape of molecules -antigens- on their surfaces. With the help of T cells, B cells make proteins called antibodies. The antibodies will help your body become aware of intruders.
Answer choices:
- A frame shift mutation in the X chromosome of a cheek cell
- A chromosomal mutation in the Y chromosome of a kidney cell
- A point mutation in the first chromosome of a sperm cell
- A substitution mutation in the third chromosome of a uterus cell
Answers:
A point mutation in the first chromosome of a sperm cell
Explanation:
Only mutations that affect the germ line are passed on to the next generation. Therefore, only mutations in the egg and sperm of an individual have the potential to affect the next generation.
Mutations in cheek cells, kidney cells, and uterus cells might cause cell death or cancer. This genetic material is not passed on to the next generation, only the egg and sperm contribute this material. Therefore, only mutations here will affect the generation.
