The key distinction is that in genetic drift allele frequencies change by chance, whereas in natural selection allele frequencies change by differential reproductive success. If the frequencies of traits in a population change purely by chance , then genetic drift has occurred.
Answer:
The correct answer is C. Proteins.
Explanation:
Amino acids are the smaller component pieces, called monomers, that are joined together to make the longer strand, or polymer, which is a protein. Amino acids are joined by covalent bonds called peptide bonds to make a polypeptide chain, which eventually creates proteins in our cells. There are 20 different amino acids in our cells that come together in a unique order to create the proteins organisms need.
Hope this helps!

Explanation:
They both eat the same thing which is plants this will either cause one of the species to flee to new land with plants or a fight among them for survival
Answer:
1.- Prophase:
Cohesins join sister chromatids of duplicated chromosome.
2.- Prometaphase:
Microtubules attach to kinetochores.
3.- Metaphase:
Kinetochores are motionless in relation to poles of cell.
4.- Anaphase:
Kinetochores move toward poles of cell
5.- Telophase:
Spindle micrutubules disassemble.
In the deep waters of the ocean, coral reefs are found in abundance. Algae live on these coral reefs, providing nutrition and producing pigments that give color to the corals. The corals offer shelter to the algae. So, they share a association. Climate change has led to increased temperatures and has caused the corals to throw away the algae living inside them. This action causes the corals to be bleached because of a lack of pigment. This change will lead to a decrease in the coral growth, reduced fecundity and can cause death of corals.
