Dna replication a) is a slow process that results in virtually no errors. b) requires dna polymerase and rna polymerase. c) is a very fast process that results in numerous errors. d) requires the cooperation of over a dozen enzymes and other proteins.

B) requires DNA polymerase and RNA polymerase

Explanation:

DNA replication is mainly maid by the DNA polymerase and RNA polymerase enzymes, it needs others enzymes like helicase but are not a dozen of them.

DNA polymerase synthesize DNA in a main chain of DNA but needs a primer of RNA that is made by the RNA polymerase. With this process the DNA and RNA polymerase synthesize a new DNA chain that is bind to the main chain.

explanation:

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.
