What species consists of four blood types: a, b, ab, & o?

a) chimpanzee
b) dog
c) frog
d) human

i would have to say D human as its the most common ive herd of for the human race

hope this helps

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
