1 / 10

What does radiation damage to a cell nucleus, like a change in the chromosome, potentially lead to?

Increased division rate

Immediate cell death

Mutation and possibly cancer

Increased metabolic rate

2 / 10

Which factors affect a cell's sensitivity to radiation?

High division rate, lower metabolic rate, non-specialized nature, high level of oxygenation

Low division rate, higher metabolic rate, specialized nature, low level of oxygenation

Low division rate, higher metabolic rate, non-specialized nature, high level of oxygenation

High division rate, lower metabolic rate, specialized nature, low level of oxygenation

3 / 10

What is the Law of Bergonie and Tribondeau (1906) referring to?

Radio-sensitivity is directly proportional to metabolic rate and inversely proportional to nourishment

Radio-sensitivity is directly proportional to division rate and inversely proportional to specialization

Radio-sensitivity is directly proportional to nourishment and inversely proportional to metabolic rate

Radio-sensitivity is directly proportional to reproductive capacity and inversely proportional to differentiation

4 / 10
