based on the excerpt, which statement best summarizes the author’s beliefs about the disappearing species? the loss of plant species and habitats will lead to widespread animal extinction. the loss of plant species and habitats will lead to environmental problems in remote regions. the loss of plant species and habitats will displace animals and decrease human wealth. the loss of plant species and habitats will devastate animals and hinder human progress.

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.

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
