Answer:

Angle of light source

Explanation:

Independent variable is the variable that the experimenter changes or manipulates in an experiment in order to bring about a measurable response, which is the dependent variable.

In this question, a student wants to investigate the effects of phototropism in bean plants. She places a light source directly above one plant, at a forty-five degree angle to another, and at a ninety-degree angle from the third. This shows that the variable being manipulated (independent variable) is the ANGLE OF THE LIGHT SOURCE.

Answer:

prezygotic ... behavioral isolation

Explanation:

Prezygotic barrier is a reproductive barrier that occurs when fertilization is prevented from occurring as a result of isolation leading to prevention of copulation, and as such there is no fusion of gametes for fertilization to take place, and eventually formation of zygote. Zygote is not formed as fertilization does not take place.

Behavioral isolation is a prezygotic reproductive barrier that prevents two or more different species to copulate together in order for fertilization to take place due to differences in behavior that is unique to each species. One of such behaviors is mating calls.

As a result of the differences in mating calls which is unique to each species of frogs mentioned in the question, only members of each species get attracted to themselves and mate with their members, thereby making it almost impossible for the three different species of frogs to mate together.
