Answer:
The correct answer would be the loss of its function.
Being protein in nature, the function of insulin depends on the amino acid sequence of the polypeptide chains.
Change in the amino acid sequence may result in a change of shape or structure of the protein.
Consequently, it would not be able to interact with cell surface receptors.
Thus, it would lose its function.
Answer:
No, it is not possible
Explanation:
Humans use the ABO blood group system where the A and B alleles are dominant over allele O but codominant with one another.
This system is such that;
Type A can only have genotype: iAiA or iAi
Type B can only have genotype: iBiB or iBi
Type AB can only have genotype: iAiB
Type O can only have genotype: ii
According to this question, a woman has blood Type A (iAiA or iAi) and her baby has blood Type AB (iAiB). This means that the father definitely contributed the allele B in order to have a baby with type AB. It also means that, according to the question, IT IS NOT POSSIBLE FOR A "Type A" father to produce that baby (see the punnet square attached).
Note: The father must contain an allele B in his genotype i.e. the father must be either type B (iBiB or iBi) or type AB (iAiB)
Answer and Explanation:

On the surface of the heart, there's coronary arteries. It supplies oxygen and blood to the heart muscle. The major blood vessels that enter the heart are the superior vena cava, the inferior vena cava, and the pulmonary veins.
