The first one. Gametes are the reproductive cells: sperm and egg cells. These contain the info that is passed on to the offspring, so an inherited mutation must be present in the gametes.

Answer:
Neurilemma
Explanation:
Schwann cells are the neuroglia that produces myelin sheaths. There is a formation of multiple layers of the glial plasma membrane around axons. The cytoplasm and nucleus of Schwann cells from the outermost layer while the inner part has multiple layers of the Schwann cell membrane. The outer nucleated cytoplasmic layer of the Schwann cell that encloses the myelin sheath is called neurolemma. It is found only around axons in the PNS. Its function is to serve in the regeneration of injured axons by the formation of a regeneration tube.
The dependent variable is the data we collect during the experiment. This data is collected as a result of changing the independent variable.
