Answer:
a system, or a group of interconnected elements, formed by the interaction of a community of organisms with their environment.
Explanation:
The answer is electron transport chain. It is a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples the electron transfer with the transfer of protons across a membrane. Electrons are transferred from NADH and FADH2 (proton donors) through the electron chain to oxygen, which is reduced to water. This process produces 34 ATP molecules and water from the carrier molecules.
Answer: AB blood type is an example of codominance
Explanation:
The AB blood group is inherited as a result of codominance. If a person receives one group A allele from one parent and one group B allele from the other, both the A and B alleles are expressed, and the individual's blood group is AB.
