Answer:
The correct answer is C.
Explanation:
The amount of genetic variation in two humans is 0.1 percent of their genome. Human genetic variation refers to the biological difference that exists in the human population.
The genetic variation in humans and apes genome is about 4 percent which is 35 million differences in a single nucleotide.
The genetic variation between apes and humans (Homo sapiens), according to scientists includes gene expression differences, variation in the transportable elements and type and number of repetitive genomic DNA transportable elements, the difference in the gene sequence, single nucleotide polymorphic, etc.
According to research, 97 percent of humans and orangutans genomes are identical. Based on evolution, among all apes, the orangutans are very special as it has been stable for the past 15 million years.
Therefore, is the genetic variation between humans and orangutans is the greatest.
Answer: The role of water in metamorphism is determined by the independent variables rock pressure, temperature, water pressure, and the amount of water present.

Answer:
C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.
Explanation:
A coenzyme is an organic cofactor that binds with an enzyme in order to initiate or aid the function of the enzyme. A coenzyme binds to the active site of the enzyme (where the reaction occurs), thereby triggering its activation by modifying protein structure during the reaction. Some examples of coenzymes include Coenzyme A and Adenosine triphosphate (ATP). Pyridoxal phosphate is a coenzyme (it is the active form of vitamin B6) that is required for the function of cystathionase. Moreover, cystathionase is an enzyme that enables cells the synthesis of cysteine from methionine (transsulfuration pathway). The binding of pyridoxal phosphate to the enzyme increases the binding affinity of the enzyme for the substrate, thereby influencing its activity. In this case, it is expected that mutation 1 reduces the binding affinity of the enzyme to the cofactor, and thereby the cofactor is required at a higher concentration to restore normal enzyme activity.
