Which of the following is true about cell differentiation when the body tries to heal from an injury?(1 point)
Responses
Cells grow during the synthesis phase of the cell cycle in preparation for senescence.
Cells grow during the synthesis phase of the cell cycle in preparation for senescence.
Stem cells differentiate to provide specialized cells that replace damaged tissue.
Stem cells differentiate to provide specialized cells that replace damaged tissue.
Damaged cells proliferate until the wound heals.
Damaged cells proliferate until the wound heals.
Platelets express different sections of RNA in order to create skin cells.
Stem cells differentiate to provide specialized cells that replace damaged tissue.
The correct answer is:
Stem cells differentiate to provide specialized cells that replace damaged tissue.
To determine which of the responses is true about cell differentiation when the body tries to heal from an injury, we can go through each option:
Option 1: "Cells grow during the synthesis phase of the cell cycle in preparation for senescence."
This option contains the same statement twice. It suggests that cells grow during the synthesis phase of the cell cycle in preparation for senescence. However, the statement is not accurate when it comes to cell differentiation during the healing process. Senescence refers to a state of irreversible cell cycle arrest, which is not related to the healing process.
Option 2: "Stem cells differentiate to provide specialized cells that replace damaged tissue."
This option correctly states that stem cells differentiate to provide specialized cells that replace damaged tissue. During the healing process, stem cells play a crucial role in regenerating and repairing damaged tissues by differentiating into specific cell types.
Option 3: "Damaged cells proliferate until the wound heals."
This option suggests that damaged cells proliferate until the wound heals. While it is true that cell proliferation can occur during wound healing to some extent, it is not primarily the damaged cells that proliferate. Instead, it is the nearby healthy cells and stem cells that undergo proliferation to contribute to tissue repair.
Option 4: "Platelets express different sections of RNA in order to create skin cells."
This option is unrelated to cell differentiation during the healing process. Platelets are responsible for blood clotting, and they do not directly contribute to creating skin cells.
Based on the explanations above, the true statement about cell differentiation when the body tries to heal from an injury is Option 2: "Stem cells differentiate to provide specialized cells that replace damaged tissue."
