Answer:
To control what enters and leaves the cell.
Explanation:
A covalent bond in which the electrons are shared unequally is called a(n) polar covalent bond. The atoms of the bond have partial negative and positive poles due to unequal electron distribution.
An electron exchange that results in the formation of electron pairs between atoms is known as a covalent bond. When atoms share electrons, a stable equilibrium of the attractive and repulsive forces between them is known as covalent bonding. These electron pairs are also known as shared pairs or bonding pairs. Since most interactions between carbon molecules include covalent bonds, covalent bonds are particularly significant. By sharing electrons with other molecules through covalent bonds, molecules can form extensive chains of compounds.
When atoms are distributed unevenly in a covalent connection, a polar covalent bond develops. Specifically, when the two atoms in the bond have electronegativities that range between 0.4 and 1.7. Polar covalent bonds and polar bonds are frequently used interchangeably.

Number one is D
Number 2 is b im pretty sure
Answer:
C. Only one allele appears for that gene in that population.
Explanation:
This totally explains what happens during gene fixation because when it happens in a small population, it tends to make one of its allele to appear for the said gene.
Furthermore, fixation can be explained as the change in a gene pool from a situation where there exists at least two variants of a particular allele to a situation where only one of the alleles is left. In the absence of mutation, any allele must eventually be fixed or lost completely from the population. Whether a gene will ultimately be lost or fixed is dependent on selection coefficients and chance fluctuations in allelic proportions.
