Explain the difference between blood types ab and o.

The difference between AB and O blood types has to do with the antigens you have or don’t have on your red blood cells.

AB blood has both A and B antigens on its red blood cells and

O blood has neither A nor B antigens on its red blood cells

Explanation:

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.
