An enzyme-catalyzed reaction was run at five different temperatures (trials 1-5). The results are shown in the data table above. Based on the data, what is the optimal
temperature at which this enzyme functions? (2 points)
O 20°C
O 40°C
O 60°C
O 70°C

Maybe 40°C

Explanation:

because at higher temperatures the enzymes get denatured lost their shapes so maybe its 40°C

i hope it's right if not so advance sorry :)

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.
