Which area would you expect to have the highest species diversity?
the top of mt. everest
a rain forest
a desert
a polluted lake

A rain forest would have the most species diversity if you are talking about complex eukaryotic organisms (reptiles, mammals etc), though the polluted lake would have the most simple prokaryotic organisms ( bacteria, protists, fungi etc.)

Ithink option a is correct because you cannot donate a different blood group than yours because it won't match.option a says betsy can donate to mark. they have the same blood group so donation can happen.
