As nac2h3o2(s) is stirred into water and dissolves, the electrical conductivity of the solution decreases, increases, remains the same

Option B, increases

Explanation:

If we arrange NaC2H3O2, we will get CH3COONa. As it is dissolved in water, it dissociates into ions

Positive ion - Na+

Negative ions - CH3COO-

In chemistry, electrical conductivity is defined as the amount of ionic concentration in a solution. With dissociation of CH3COONa, the ionic concentration increases and hence the electrical conductivity also increases.

hence, option B is correct

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.

yes it is weird but true
