Compare cytoskeleton, skeletal system, and muscular system.
They both ...

The cytoskeleton is similar to the skeletal and muscular system . They both provide structure and allows for movement within the cell . The cell membrane is similar to the integumentary system . They both separate and protects the internal structures from the external environment and it regulates water loss . The mitochondria is similar to the digestive system

Explanation:

:D

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.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
