Explanation: always remember the number above is the atomic number
Environmental factors often influence traits independently of genes. Either of these effects can change the proteins that are made from a gene, which in turn affects traits.
How do environment and gene determine our personality?
Some genes increase the characteristic and others work to decrease the same characteristic-complex relationship among the various genes, as well as a variety of random factors, produce the final outcome.
Because of their genetic makeup, individuals differ in their responsiveness to the qualities of the environment. There are unique, genetically influenced reactions to particular experiences to which we are exposed.
The presence of drugs and chemicals in an organism's environment can also influence gene expression in the organism. The environment can affect morphological and physiological development whereas genes influence morphology and physiology, creating a framework within which the environment acts to shape the behavior of an individual.
Hence in this way, genes and environmental influences work together to determine our characteristics.

A control group is sort of the normal group. The group you aren't changing or messing with. It is to show what the species/experiment acts like on its own in response to something without you having to change it at all.
With an experimental group, you are changing something about the subject before putting it in the conditions it will need to respond to.
I don't entirely understand, but I know the control group is constant, unchanging. It sort of helps with distinguishing things. I have examples of experiments if that will help you understand what a control group is to answer the question. I also have a The Death Cure example if you have seen or read the book. I hope you do not fail this assignment, but even if I did not answer with an answer you were looking for, it could have helped you answer the question on your own.
I saw somewhere a similar question, though I was given the answer choices. If this is the answer you are looking for: variable(s).
Control groups don't use variables because you aren't changing them.
