Ascientific law is
a. a universally accepted conclusion based on testing
b. always changing as new evidence is presented
c. based on new evolving theories, often debated in the scientific community
d. one step toward forming a theory

A. a universally accepted conclusion based on testing

Explanation:

A scientific law is a statement or a description of a naturally occurring phenomenon. It is often expressed in mathematical terms. Scientific laws are conclusions that came about after repeated experimentation and testing. They do not change by new discoveries instead, they are developed by adding into it. They are universally accepted in the scientific world. One thing that differentiates it from scientific theory is that it just shows the what, but does not explain the how and the why these phenomena occur.

A. a universally accepted conclusion based on testing

Explanation - Scientific theory is given as an answer to a natural happening in the earth but scientific laws are detailed idea of how nature will act under certain conditions. Theories are given after an experiment has been performed under controlled conditions.

Scientific theory cannot be changed to scientific laws and scientific laws cannot be changed to scientific theory. Scientific theories are broader in scope, and give overall clarifications of how nature functions and why it shows certain attributes.

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.
