Answer:
(B) agglutination with anti-A antibodies.
Explanation:
ABO blood type is based on two types of antigens: A and B antigens. The anti-A antibodies react with antigen A while anti-B antibodies react with antigen B.
Blood type A has antigen A on the surface of its red blood cells and anti B antibodies in its plasma. Due to the presence of antigen A on its red blood cells, the blood type A shows agglutination with anti A antibodies.
The brain is most of the ape's main gimmicks, aside from the opposable thumb. It allows us to not die without claws, fangs, and other evolutionary benefits.
<span>If I were attempting to date a rock sample that I suspect to be incredibly old, i would use radioactive isotopes with a long half life. When dating rocks and fossils to discover approximately how old they are, radioisotope dating is used on igneous rocks found near fossils. Things like Uranium 235, which is an unstable radioactive isotope of elements, decays at a constant rate over time so can be useful in determining age.</span>
I believe your Answer would be:
A: Sister Chromatids.
Explanation:
A sister chromatid refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. In other words, a sister chromatid may also be said to be 'one-half' of the duplicated chromosome.
