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:
Antibiotics inhibit enzymes specific to bacteria and have no effect on virally encoded enzymes
Explanation:
The specificity of the antibiotics to inhibits some bacterial enzymes is one of the major reasons why antibiotic do not affect viruses.In addition antibiotics are designed to have a significant destructive effects on the mechanisms of biochemical reactions in bacteria and its physiology, e,g on the cells walls,( inhibiting the formation of peptydoglycans) on certain organelles e,g ribisomes (inhibiting protein synthesis) and on the DNA(disrupting replication). The virus physiology is different from bacteria, therefore the design of antibiotics will nor affect these same mechanisms in viruses, thus no specificity for the antibiotic to act on in virus
