the model shows tectonic plate activity. at which two locations in the model is crust material being subducted

well we can't tell you because we cant see the time give a screen shot or something.

not sure but try c two haploid cells

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.
