The scenario that represents mitosis in action is:
b) a skin cell repairing itself after a cut.
Mitosis is the process by which a single cell divides to produce two genetically identical daughter cells, and it plays a key role in growth and repair of tissues, such as the skin. The other options involve processes that are not related to mitosis:
- a) A bacterium dividing into two daughter cells is a process called binary fission, not mitosis.
- c) A liver cell preparing to produce enzymes refers to cellular processes like transcription and translation, but not mitosis.
- d) A sperm cell fusing with an egg cell refers to fertilization, not mitosis.
