Answer:

Pheromones

Explanation:

Pheromones play an important role in the behavioral isolation of insect species. These compounds serve to identify individuals of the same species and of the same or different sex. Evaporated molecules of volatile pheromones can serve as a wide-reaching chemical signal. In other cases, pheromones may be detected only at a short distance or by contact.

Hello. This question is incomplete. The complete question is:

" There are several mechanisms through which reproductive Isolation occurs. Which situation is an example of behavioral isolation?

A. Mules, the offspring of a male donkey and a female horse, are unable to reproduce because they are sterile. B. Red and purple sea urchins cannot reproduce with one another because the sperm and egg cannot fuse. C. The reproductive organs of snails only properly align when the male and female belong to the same species. D. Males of different, closely related species of fireflies signal for mates by flashing different light sequences. "

Answer:

D. Males of different, closely related species of fireflies signal for mates by flashing different light sequences.

Explanation:

Behavioral isolation is a type of reproductive isolation and is the most important type of prezygotic isolation. This process consists of different types of premarital nuptial stops, which are genetically defined and intended to arouse the partner. When this type of isolating mechanism acts we can visualize sexual courting, displays and signs of recognition between individuals of the same species that do not exist, which prevents sexual attraction between populations. We have as an example fireflies, where the male flash the light on their bodies to provoke the sexual arousal of females.

Why do scientists use a control group in experimental design???

givi [52]

Having a controlled group is very important.

Reason: If scientists did not have a controlled group then, they would have data for the test but they might know if the results changed or not. Scientists need a controlled group because the controlled group is like the original. They need the original group to help them know what improved or did not improve.

For example, if you were testing whether or not different types of music helps with studying, then you will need a group that does not listen to music so you can know if different types of music actually improve or just make studying worse.

Having a controlled group helps you know the difference between observations in a easier way. The controlled group is not something people should ignore. It might seem useless at first but, when a person starts to finish up their project or test then, they will understand why a controlled group is important. By the time they do, it might be too late so make sure you people use a controlled group(Especially in the Science Projects).

(Hope this helps : ) )
