Question

which of the following is true about cell differentiation when the body tries to heal from an injury? (1 point)

• 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.
• cells grow during the synthesis phase of the cell cycle in preparation for senescence.

Explanation:

• Damaged cells cannot proliferate to heal wounds; they are typically removed or replaced.
• Platelets are involved in clotting, not differentiating into skin cells via RNA expression.
• Stem cells are unspecialized cells that can differentiate into the specific specialized cells needed to replace damaged tissue during wound healing.
• The synthesis phase of the cell cycle involves DNA replication, not growth for senescence, and this is not related to injury healing via differentiation.

Answer:

Stem cells differentiate to provide specialized cells that replace damaged tissue.
