Answer:
A G- protein
Explanation:
G proteins are molecules involved in signal transduction. They are often referred to as guanine nucleotide binding proteins. They bind to signal molecules at the exterior of the cell and are responsible for transmitting the signals from the exterior of a cell to the inside of the cell, which then results to a cellular response. G proteins are generally activated by a set of trans-membrane receptors called G protein coupled receptors and then deactivated by a set of proteins called the Regulator of G protein signaling (RGS proteins). In regulation, G proteins bind to GTP when they are active, but bind to GDP when they are inactive.

Answer:
mutations
Explanation:
Mutations are changes in DNA sequence that can create genetic variation within the population and thus are the ultimate source of new alleles . Mutations are important for evolution because of their ability to form a new genetic variant (allele) that can be spread to the offspring. If a new variant of a trait formed by a mutation is advantageous and helps the organism to survive and reproduce, it is going to be favourable by natural selection. That variation will more likely be passed to the next generation and remain over time.
