The Process of mitosis and cytokinesis are used by humans in which of the following?
I. asexual reproduction
II. growth
III. repair
IV. replacement
a
I only
b
II only
c
II, III, and IV only
d
I, II, III and IV
d) I, II, III and IV
The process of mitosis and cytokinesis in humans is involved in all of the options provided - asexual reproduction, growth, repair, and replacement.
To arrive at this answer, we can go through the options one by one:
I. Asexual reproduction: Mitosis, the process by which cells divide to give rise to two identical daughter cells, is a form of asexual reproduction. So, option I is correct.
II. Growth: Mitosis and cytokinesis are crucial for the growth of an organism. Through mitosis, cells divide and increase in number, leading to growth. So, option II is correct.
III. Repair: When tissues in the body are damaged, mitosis and cytokinesis enable the repair process. By dividing and producing new cells, damaged tissues can be replaced and repair can occur. So, option III is correct.
IV. Replacement: Mitosis allows for the replacement of old and worn-out cells with new ones. This applies to various tissues in the body, such as the skin, lining of the gut, and blood cells. So, option IV is correct.
Therefore, the correct answer is option d: I, II, III, and IV.
The correct answer is:
d) I, II, III, and IV
Mitosis and cytokinesis are used by humans in various processes, including:
I. Asexual reproduction: Mitosis and cytokinesis allow for the production of genetically identical daughter cells, which is a form of asexual reproduction.
II. Growth: During the growth of an organism, mitosis and cytokinesis allow for the replication and division of cells, leading to an increase in the overall size of the organism.
III. Repair: In response to injury or damage, mitosis and cytokinesis enable the regeneration of tissues and organs by replacing damaged cells with new, healthy cells.
IV. Replacement: Mitosis and cytokinesis are involved in the constant turnover of cells, allowing for the replacement of old or worn-out cells with new ones.
