You are studying mitosis in a species of snake. You notice that during mitosis of diploid cells there are 7 groups of chromosomes on the metaphase plate. Is it surprising that this is an odd number? Why or why not?

No, this is not surprising

Explanation:

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.
