Answer:
Codominant and multiple alleles
Explanation:
Human blood types are an example of codominance, because both A and B alleles are expressed equally.
It cannot be complete dominance because neither the A or B allele are expressed over the other. I.e., neither are recessive.
It is not polygenic, as A B and O are multiple alleles of the same gene. Polygenic is when several genes control one trait. Therefore, it also represents a case of multiple alleles.
Sex linked traits are those present on the X chromosome, and we are told here that the gene is found on chromosome 9. Therefore it cannot be sex linked.
Incomplete dominance and codominance are similar but have different outcomes. instead of both alleles being expressed as in codominance, the resulting heterozygous phenotype is a 'blended' phenotype that is distinct from either homozygote. E.g. a red flower mated with a white flower producing pink flowers
There are two types of cellular respiration; anaerobic respiration and aerobic respiration. In anaerobic respiration 2 ATP (adenosine triphosphate; the cell's main unit of energy) per molecule of glucose is produced via glycolysis (as oxygen is needed for the tricarboxylic acid cycle and electron transport chain). In contrast to aerobic respiration wherein 36 ATP is produced per molecule of glucose because of the tricaroboxylic acid cycle and electron transport chain. Aerobic respiration is 18 times more efficient than anaerobic respiration.
The overall efficiency of aerobic respiration is around 40% and since aerobic respiration is 18 times more efficient than anaerobic respiration, then the overall efficiency of anaerobic respiration is around 2.22%.
