Pretty sure the answer is A
Answer:
Incomplete dominance can be described as a phenomenon in which the dominant trait is not completely dominant over the recessive trait. Incomplete dominance can be determined when the dominant and the recessive trait merge to form a third type of trait. A new phenotype arises due to such a cross.
For example, when a black-feathered chicken is crossed with a white chicken and their alleles shown incomplete dominance, then offsprings having blue feathers can be seen.
Answer:
The citric acid cycle is fundamental to produce the energy needed for aerobic cell metabolism, thereby mutations in the enzymes involved in this metabolic pathway would be lethal to the individual
Explanation:
In aerobic organisms, the citric acid cycle (also known as the Krebs cycle), is a key metabolic pathway used to remove electrons and uses them in the electron transport chain in order to generate adenosine triphosphate (ATP), the energy currency of the cell. The citric acid cycle depends on eight enzymes that oxidize acetyl-CoA into two molecules each of carbon dioxide (CO2) and water (H2O). Thus, the citric acid cycle is a series of chemical reactions that are key to breakdown carbohydrates, fats and proteins into CO2 and H2O in order to produce energy (ATP).
