earthworms have tiny bristles called setae which usually stay inside of their bodies. they can, however, jab them into the surrounding dirt to them move forward. what is another way that earthworms often use their setae?
a. to anchor themselves to the ground when a bird tries to pull them away
b. to push dirt in their mouths when eating
c. to oxygen diffuse through their skin better
d. to glide along the surfaces of water bodies

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.

i think the answer is 95 hope this
