katovenus [111]

Answer and Explanation: The figure below shows the doses of BPA administered to the female mice over time.

An experiment is used to determine cause and effect among variables. When the research is for the impact of a treatment, researchers randomly separate individuals in two groups:

Control Group doesn't receive any treament or a placebo or a treatment whose outcome is already known;
Treatment Group receives the treatment;

For the female mice on the image below, in the First Group is not injected any dosage of BPA, so they are the control group, while the others are treatment group.

The variables in a experiment are classified as independents or dependents:

Independent Variable is the cause;
Dependent Variable is the effect;

For the BPA research, since it is the effect of BPA over time on the mice's cells it is being investigated, dosage of BPA is the independent variable and time is the dependent variable.

Vesnalui [34]

Answer:

That enhances the sensitivity of cancerous tumor cells toward the applied radiation dose.

Explanation:

It is a known fact that tumor cells are very hard to treat so, to increase their sensitivity toward radiation, the body of the patient is treated with special kind of cytotoxic drugs that enhance the sensitivity or exposure of those cancerous cells toward radiation and made them vulnerable. These drugs are applied to modern approaches because of their extensive action toward tumor cells.
