The correct answer is Manganese (Mn).
<span>Manganese functions as a cofactor for a large variety of enzymes with many functions including those active in gluconeogenesis. <span>Pyruvate carboxylase that catalyzes breakdown of pyruvate to oxaloacetate requires manganese (or magnesium) for its function. Phosphoenolpyruvate carboxykinase also needs Mn.</span></span>

Answer: c. The same as the phenotype of a homozygous AA person.
Explanation: The capital A represents the dominant property of the person’s genes. The lowercase a is recessive. This means that the dominant quality will always trump the recessive quality. That is why they are the same as the homozygous AA person.
Directional selection is where one phenotype is favored, so an example would be "a population of madagascar hissing cockroaches suffers heavy predation from lizards. Because their heads are small, the lizards are unable to eat the very largest adult cockroaches, and instead prey upon small and medium sized adults, so as a result the large cockroaches are favored and live".
Meanwhile, disruptive selection is where both extreme phenotypes are favored, an example would be "a population of rabbits can have black fur, white fur or grey fur. This population of rabbits lives in an area of white rocks. When a local volcano erupts, black volcanic rock now dots the landscape amongst the white rocks. Now the black and white rabbits live longer because the black and white spots on the landscape camoflauge them. The two extreme phenotypes are being favored."
