When conducting a biology investigation why is it important to note the safety rules and symbols

The safety rules and symbols have to be noticed when there is a biology investigation being carried on. Because by interpreting them risk can be minimized and unfortunate situations avoided.

Explanation:

To understand this we need to analyze it from a Prevention perspective. First of all, prevention is the best effort to reduce risks associated with a certain situation. In the case of a biological investigation, people have to know all it's meanings because they can know the risks. As well as to be prepared to react in case something happens. Because even though we are carrying out the best to prevent a misfortunate situation they can still happen.

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.
