Question

a giraffe has 36 chromosomes in its body cells. a giraffe skin cell undergoes mitosis, how many chromosomes would you expect to see in the resulting daughter cells?
o a impossible to determine without a microscope
b 18
o c 36
o d 72
question 11
the process of mitosis and cytokinesis are used by humans in which of the following?
i. asexual reproduction
ii. growth
iii. repair
iv. replacement
o a i only
b ii only
o c ii, iii, and iv only
d i, ii, iii and iv

Explanation:

• Question 10: Mitosis is a process of cell division where a parent cell divides to produce two daughter cells that are genetically identical to the parent cell. Since the giraffe's body cell has 36 chromosomes, after mitosis, each daughter cell will also have 36 chromosomes.
• Question 11: Mitosis and cytokinesis are used for growth (increasing the number of cells as an organism grows), repair (replacing damaged cells), and replacement (continuously renewing cells like skin cells). Humans do not use mitosis for asexual reproduction as humans reproduce sexually.

Answer:

• Question 10: C. 36
• Question 11: C. II, III, and IV only
