The answer should be C, 50%
First we need to find the alleles for Mr Jones. We know that he has a blood type B, so at least one allele should be B, and the other can either be B or O (cannot be A, or else his blood type would be AB because A and B are co-dominant alleles)
Since Mr Jones' parents are both blood type AB, so which means their allels must be A and B, so, we can conclude that Mr Jones alleles should be B and B.
Now we know Mr jones' alleles, we can conduct a punnett square to find the probability. Since Mrs Jones has blood type AB, again, her alleles are also A and B.
From the punnett square attached, we can conclude that their offspring are either blood type AB or pure B. So, the answer should be 50%, C.
Mars and Earth are very different planets when it comes to temperature, size, and atmosphere, but geologic processes on the two planets are surprisingly similar. On Mars, we see volcanoes, canyons, and impact basins much like the ones we see on Earth

Answer:
B cell
Explanation:
The B cell works by producing antibodies that work against the antigen causing disease in the body. B cell is activated by a T-helper cell, which is, on the other hand, activated by antigen-presenting- cell of the innate immune system. The antibodies neutralize the antigens and allow for the phagocytic cell, such as macrophages, to ingest and destroy the cell. The antibodies also mark the antigens as a target for T-cytotoxic cells.
