A scientist wants to study snails in an ecosystem. The snails move slowly and are incapable of traveling long distances. Which method would be most effective? Which method would be least effective? Use the information you put in the chart to explain your reasoning.​

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.

it is called the mitotic spindle
