Mutations can be somatic or inherited. Somatic mutations are mutations that occur in a single body cell, so only tissues derived from mutated cell are affected. Somatic mutations are not inherited. On the other hand, inherited or germline mutations occur in gametes (egg cells and sperm cells) and are passed onto offspring. As a result of these kind of mutations each cell in the organism is affected.
Somatic mutations: BRAF and KRAS gene.
Inherited mutations: FRG2 and BRCA1 gene.

Answer:
is negative, except when there is a change in membrane permeability to ions
Explanation:
Membrane potential is voltage that result from differences in Ion concentration of cellular membrane.
Many Ions such as potassium(K+), Sodium(Na+)and chlorine(cl-) has many gradient across the membrane this gives the potential energy. If the membrane is permeable it gives rise to intake of potassium, leading to diffusion of positive charged Ion down the gradient outside the cell leading to a concentration of uncompensated net negative charge.
Hence, the membrane potential is mostly negative except there is a change in members permeability to Ion
Replica Plating refer to the process bacterial colonies are moved from a master plate to secondary plate.
<h3>What is Replica Plating?</h3>
Replica plating is method or tool use in microbiology in which one or more Petri plates that contain various solid selective growth media are inoculated with similar microorganisms colomies from a primary plate thereby reproducing the original pattern of colonies.
Therefore, Replica Plating refer to the process bacterial colonies are moved from a master plate to secondary plate.
