Why are archaea in a different domain from bacteria?

a. they had independent evolutionary development.

b. they shared a common ancient ancestor.

c. they are eukaryotes, but bacteria are prokaryotes.

d. they are multicellular, but bacteria are unicellular.

your answer is "the 1950's"

it's     c       this is a cell (b) with a nucleus (c) containing dna (a). the dna is organized into chromosomes (d). a section of the chromosome that codes for a trait is called a gene (e).

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.

idk im sorry.
