Answer:
The temperature is kept at room temperature and mostly preferred to be constant, so that the temperature does't be a variable factor effecting the accuracy of experiment.
Temperature is kept constant to take it as a control factor, so that experimental results are not effected by such outside factors. Such control variables are important in experiments as they minimize the influences from outside.
Answer:
The type of evidence is<u> Mechanical incompatibility.</u>
Explanation:
Copulation is often impossible between different animal species because of the incompatible shape and size of the genitalia.It is called mechanical incompatibility.
This isolation prevents species that diverge from interbreeding thus they lo longer able to mate with each other.
Here morphological difference takes place which ultimately leads to behavioral isolation and thus no mating takes place.
Here snail can not mate because their morphological structures are incompatible.
