Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.

a. Why do you think unicellular organisms perform asexual reproduction? (give two reasons)
b. What type of asexual reproduction do bacteria most commonly use?

A)

1: The offspring of the cell will contain the exact genes of the parent by reproducing asexually

2: They can reproduce rapidly by reproducing asexually.

B) Binary fission. One cell simply splits into two identical cells.

Explanation:

Hope that helps :D

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction

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.
