Gold has 118 neutrons. If a gold atom were to lose a neutron, what would happen

The answer is C, it's mass is lowered but it is still gold.

i think its through the fallopian tube

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.
