Answer:
<em>The correct option is B) number of patients with brain tumors</em>
Explanation:
In a scientific experiment, an independent variable is a variable which is being changed by the scientist or changes naturally. The effect of the independent variable is studied on another variable which is termed as the dependent variable. Hence, the dependent variable can be described as the variable which is under study in a scientific experiment.
In the following scenario, as the effect of prolonged cell phones is being tested on causing brain tumors hence, the number of patients with brain tumors will be the dependent variable.

Answer choices:
- A frame shift mutation in the X chromosome of a cheek cell
- A chromosomal mutation in the Y chromosome of a kidney cell
- A point mutation in the first chromosome of a sperm cell
- A substitution mutation in the third chromosome of a uterus cell
Answers:
A point mutation in the first chromosome of a sperm cell
Explanation:
Only mutations that affect the germ line are passed on to the next generation. Therefore, only mutations in the egg and sperm of an individual have the potential to affect the next generation.
Mutations in cheek cells, kidney cells, and uterus cells might cause cell death or cancer. This genetic material is not passed on to the next generation, only the egg and sperm contribute this material. Therefore, only mutations here will affect the generation.
