Answer from: leandroarguijo

The child's father has type O blood.

Explanation:

A child inherits from its parents the alleles that will determine the child's blood system. Therefore, if the child's mother has type A blood and the child has type O blood, that child may only have inherited this from his parents who also have type O blood.

For the ABO system, we say that a person has type A blood, if he has agglutinogens A in his red blood cells and, in plasma, anti-B agglutinins. The schedule happens to people of type B blood.

The presence or absence of agglutinogens in people's blood is determined by genes IA, IB or i. The IA and IB genes are dominant over the i gene. The IA gene, for example, determines the production of an enzyme that synthesizes agglutinogen A. Therefore, if one person has the IA IA genotype and another person has the IA i genotype, the red blood cells of both have agglutinogen A, that is, , they have blood type A. Something similar occurs in the case of people of blood type B. But people of type AB have genotype IA IB, because there is no dominance between these two genes. These people are capable of synthesizing both agglutinogen A and B. Finally, a type O person has genotype ii, that is, he does not have the enzymes necessary for the manufacture of neither agglutinogen.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
