In humans, ABO blood types refer to glycoproteins in the membranes of red blood cells. There are three alleles for this autosoma

l gene: IA, IB, and i. The IA allele codes for the A glycoprotein, The IB allele codes for the B glycoprotein, and the i allele doesn't code for any membrane glycoprotein. IA and IB are codominant, and i is recessive to both IA and IB. People with type A blood have the genotypes IAIA or IAi, people with type B blood are IBIB or IBi, people with type AB blood are IAIB, and people with type O blood are ii. If a woman with type AB blood marries a man with type O blood, which of the following blood types could their children possibly have?

Answer: A) A and B

Explanation: A woman with type AB blood will have a genotype IAIB while a man with type O blood will have a genotype ii. A cross between the two of them will produce four offsprings: 2 IAi and 2IBi. IAi is type A blood while IBi is type B blood. Therefore the possible blood types of their children are type A and B.

Some salts form acidic or basic solutions in water, which is a result of a process called _____.
dem82 [27]
The answer would be salt hydrolysis.

Salt that was made from the combination of weak and strong acid/base could be hydrolyzed and forming another substance. The hydrolysis process will separate the H2O into H+ and OH- and the weak part of the salt will take one of the ions(weak base will take OH-, weak acid will take H+). The result would be increased H+( or OH- ion, leading to change in pH of the solution.
