2 answers:

8 0

By process of elimination you can deduce the answer:
A mutation causing uncontrolled cell division in human tissue cells is cancer and definitely not beneficial.
A mutation resulting in partial or complete loss of chlorophyll pigments in plants will lead to a plant not being able to photosynthesise and therefore unable to respire leading to death.
A mutation resulting in a squirrel being born without ovaries means the squirrel will be unable to reproduce and there for is not beneficial.
The answer is therefore a mutation inhibiting human immunodeficiency virus from entering the host cell. This means that the person who has this gene is unable to contract HIV which is beneficial

A scientist could best determine which ion (F-, Cl-, Br-, or I-) produced the greatest electrical potential in the Experiment by

Serggg [28]

Answer:

a solution of each sodium salt at the same concentration

Explanation:

If a scientist wishes to study the electrical potential that develops between ice and the sodium salts solution of the ions (F-, Cl-, Br-, or I-) in order to determine which ion produced the greatest electrical potential; he must compare the electrical potential that develops between ice and a solution of each sodium salt at the same concentration.

This means that conclusions can not be reached unless the sodium salt of each ion at the same concentration is compared so as to ensure consistence in the results of the study.
