The answer is C.
The man’s genotype must be AB. The woman’s genotype can be either BB or BO as both correspond to a blood type (which is a phenotype) of B.
Each parent passes on one allele. The man can contribute A or B and the woman can contribute B or O.
The possible genotype combinations are therefore AB, AO, BB, and BO. These correspond to the phenotypes AB, A, B, and B.
A nonsense mutation occurs. The presence of the stop codon results im the production of a shortened, and most likely nonfictional protein.
Answer:
Antigen-presenting cells show digested antigens to T cells through the MHC on their surface, which allows the T cell to “see” the antigen and recognize it as foreign. The connection between the MHC and the receptor on the T cell is the first signal necessary to activate the T cell to respond to a tumor and destroy it.
Explanation:
Bacteria attacks the immune system, taking over the immune system cells, turning them to bacteria. Essentially making the immune system cells attack each other and multiplying.
Cellular respiration occurs in animals and plants
