Evolution is a A. theory because it is an explanation that is supported by extensive observations, experimentation, and reasoning. B. prediction because it makes an educated guess about events that will occur in the future. C. law because it has been proven without exception under certain stated conditions. D. variable because it is a factor that can be changed during experimentation.

A. theory because it is an explanation that is supported by extensive observations, experimentation, and reasoning

Explanation:

Evolution deals with theories that supports how organisms are inter-related. The inter-relationship talks about the changes in organisms(physical) from generation to generation due to different traits being inherited from parents and environmental factors.

These factors plays a major role in how organisms evolve and change.

Evolutionary processes have been observed and various experiments conducted which supports the topic.

It is thought that humans had a tail that gradually disappeared after different generations. Fossil studies and lots of experimental comparisons and reasoning confirms this findings.

i think its c. amphipod

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
