You can eat as many empty calories as you want during the day because they do not count towards your daily totals. a. true b. false

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.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
