Final answer:
Less radiosensitive cells would have a high specialization (differentiation) and a high rate of proliferation.
Step-by-step explanation:
Radiosensitivity refers to the sensitivity of cells or tissues to the damaging effects of radiation. Cells that are highly specialized and have a high rate of proliferation are generally less radiosensitive because they are more differentiated and have a stronger ability to repair themselves.
For example, cells in the bone marrow, which are constantly dividing to produce new blood cells, are more radiosensitive because they have a high rate of proliferation. On the other hand, cells in the brain, which are highly specialized and have low rates of proliferation, are less radiosensitive.
