Genes B and C with 10% recombination frequency are closest to each other. Because recombination happens at random, the distance between genes that are farther from each other creates higher recombination frequency. A low recombination frequency of 10% means the genes are closest to each other. The short distance between the two genes allow fewer recombination to happen, thus the frequency is low.
Answer:
A theory is a reasonable explanation of the phenomena observed in nature, with much evidence to support it (option C).
Explanation:
A theory gathers a set of hypotheses that can be demonstrated and constituted on a scientific basis, until they are questioned by other evidence.
To construct a theory, the processes of observation, deduction and investigation must be thorough, but leave open the possibility of being discussed and refuted in the absence of definitive arguments.
<u>A theory becomes law when it has been proven beyond a doubt</u>.

Answer:
The hormone epinephrine binds to a specific receptor on the plasma membrane of the liver cell.
Explanation:
Glycogen is the body's rapid energy supply, which is how glucose, the main energy source of cells - derived from carbohydrate consumption - is stored. Glycogen is found mainly in muscle (muscle glycogen) and liver (liver glycogen), where liver cells are found. Glycogen is important for the production of ATP in muscle cells and most other cell types.
Based on this information, researcher Earl Wilbur Sutherland Jr. decided to conduct a study to find out what were the effects of epinephrine during glycogen metabolism on liver cells. In this study, the researcher concluded that during the process of glycogen decomposition into glucose, the epinephrine hormone binds to a specific receptor on the liver cell plasma membrane.
