Answer:
When a certain type of rock, specifically, an igneous rock, is deeper into the ground, and it is under the influence of high temperatures and pressures, it will start to change its molecular structure over time. In addition to the high temperature and pressure, chemical influences are also very important, so the the rock will gradually turn into a metamorphic rock.
Depending on the type of influences, and their intensity as well, one type of rock can evolve into multiple different types of metamorphic rocks.

Answer:
<u>B) 3 amino acids joined by 2 peptide bonds</u>
Explanation:
The general formula of amino acids:
<u>R-CH(NH2)-COOH </u>
It can be seen clearly in the attached image that there are three amino acid molecules.
Now the three molecules of amino acids are joined by 2 peptide bonds.
<u>Peptide bond: </u> a bond formed between first carbon of one amino acid and nitrogen of another amino acid releasing a water molecule( H2O).
Answer;
-Allele frequency change
In single-gene traits, natural selection can lead to allele frequency change.
Explanation;
-Allele frequencies can change over time within a single population, and frequently differ between populations. This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift.
-Random forces lead to genetic drift. Sometimes, there can be random fluctuations in the numbers of alleles in a population. These changes in relative allele frequency, called genetic drift, can either increase or decrease by chance over time.
