Describe why dna replication is said to be a semiconservative process

really dont know just need some points

one would be wind another would be water density

is this a psat question, if so do not cheat try your best.

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.
