C:Primary cause i was asked this question and that is what the answer was
I don't think any compounds are made of protiens but they do contain them. Enzymes are protiens that catalize reactions, the liver contain many protiens, amylase is another that is in saliva.
A chromosome contains one long DNA molecule.
Each gene in this DNA molecule gives the instructions for making a protein.
Both chromosomes in a pair of homologous chromosomes have the same genes, but the genes in these 2 homologous chromosomes may have different alleles.
Alleles are basically different versions of the given gene.
new species can form through allopatric or sympatric speciation. the mechanisms of genetic drift will act more strongly on populations that are initially separated in allopatry than on those initially separated in sympatry.
<h3>What is
genetic drift ?</h3>
In a population, genetic drift refers to a shift brought on by chance in the frequency of an already present gene variant. Gene variations could completely vanish due to genetic drift, which would limit genetic diversity. Furthermore, it may lead to the widespread spread and even fixation of previously rare alleles.
<h3>Why does it happen?</h3>
The term "genetic drift" refers to haphazard changes in the population's gene variation frequency. Genetic drift occurs throughout time when the frequency of different alleles, or variable forms of a gene, fluctuates randomly. Allele frequencies are changed to account for these variations in allele presence.

Osmosis is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.It may also be used to describe a physical process in which any solvent moves across a semipermeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations.Osmosis can be made to do work.
Osmotic pressure is defined as the external pressure required to be applied so that there is no net movement of solvent across the membrane.
