Write the difference between a. Soil formation and Soil erosion

b. Soil pollution and Soil profile

a.

In soil erosion, the soil is carried away from by the wind or water from the top layer of the ground. Soil formation is making soil. It can be by the deposition of the soil from water or wind

for the points

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.
