A scientist is studying changes in the genetic material that affect the traits of an individual. In which part of the cell must the scientist focus her studies?

Mutations can be defined as changes that occur in the genetic material (DNA) of living organisms. These changes are an important source of genetic variability, and are often responsible for the emergence of new species. Changes in genetic material are extremely important, as it is DNA that carries the information necessary for protein synthesis. Some modifications in the genes directly affect the protein to be synthesized, resulting in the appearance of an unexpected characteristic. It is worth noting that mutations in DNA can cause everything from physical changes to behavioral changes. This way, he has to focus on the DNA of the cell.

Explanation:

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
