2 / 10

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

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

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

3 / 10

What can be said about radio-sensitivity between different individuals and genders?

It is always higher in males

It is always higher in females

It is always the same

It may differ

4 / 10

Which of the following tissues are considered radio-resistant?

Blood-forming cells, intestinal tract cells, hair follicles, sperm-forming cells

Red bone marrow, spleen, lymph nodes, thymus

Germinal cells, hematopoietic tissues, basal cells of skin, epithelium of gastrointestinal tract

5 / 10

What might happen to cells if damaged by ionizing radiation but not repaired or incompletely repaired?

They may die immediately

They may transform into other cell types

They may operate abnormally

They may increase in number rapidly

6 / 10

What are the possible effects of ionizing radiation on a cell?

Increased sensitivity, repaired damage, rapid growth, death

No damage, repaired damage, abnormally operating, death

Increased division, repaired damage, abnormally operating, cancer

No damage, mutation, cancer, death

7 / 10

What happens to most animals exposed to a whole body exposure of 600 - 700 R?

They will likely mutate

They will likely develop cancer

They will likely become more resistant to radiation

They will likely die

8 / 10

Oxygen

Hydrogen peroxide

Methane

Carbon dioxide

9 / 10

Which factors affect a cell's sensitivity to radiation?

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

10 / 10

Mutation and possibly cancer

Increased division rate

Immediate cell death

Increased metabolic rate
