Name one organ in the body and explain its function.

The heart, its function is to plump blood to the rest of the body

The heart

Explantion in details: The heart is a muscular organ that can be found in most animals, it pumps blood through the blood vessels of the circulatory system.Blood provides the body with your oxygen and your nutrients, as well as helping in the removal of metabolic wastes. In humans, the heart is located between the lungs, in the middle compartment of the chest. Without the heart we will die within seconds because all blood is no loger being pumped out of it :)

I hope this helps a thank and a brainlist would be greatly appreciated :))

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.
