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.
Increasing the concentration of carbon dioxide increases the rate of photosynthesis, as there is a greater supply of it that can be used. Of course, you can only add so much carbon dioxide before the plant can’t perform photosynthesis at an any faster rate. Increased carbon dioxide concentration will increase the rate of photosynthesis until it is no longer the limiting factor in the reaction.

The function of the ovaries and testicles is to form the sexual gametes for the formation of a new being (zygote, embryo). So probably the correct answer is the C
