Label each target to indicate if the interaction between the molecules inside the rectangle contributes to surface tension (t), adhesion (a), or cohesion (c). note that one target should be left blank because the molecules inside that rectangle are not involved in any of these interactions.

b - the respond is innate and varies over time.

good luck!

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.
