Answer:
Behavioral isolation
Explanation:
The reproductive isolation refers to the mechanism which prevents the interbreeding between the organism. The mechanisms of reproductive isolation can be categorised into two types: The pre-zygotic and post-zygotic barriers.
The prezygotic isolation mechanisms are the behavioural, the habitat, mechanical and gametic isolation.
In the given question, the type of mechanism involved in the population of frog will be the "behavioural isolation" as the population of frog differ in their behaviour of mating ritual or mating calls which does not allow the frogs to mate.
Thus, Behavioral isolation is the correct answer.
If cave salamander didn’t evolve from sighted ancestors, it eyes would be a vestigial structure.
Cave salamanders live in the zone, with complete lack of light (dark zone), so this organisms adapted to that environment with blindness. It is believed that cave salamanders evolved from the ones that could see. The explanation of why they lost their sight is that they conserved energy needed to maintain sight to be more successful in reproduction.

as a pesticide since the 19th century used especially during World War I to control typhus and malaria
vectors. The chemical had application as
