Species A has a breeding call that is completely different from Species B. This difference in breeding call leads to
Minchanka [31]

Answer: The correct answer is option a.

Explanation:

Prezygotic isolation is a mechanism by which mating and fertilization is prevented. Thus, it prevents the formation of a zygote.

It can be achieved by various reasons such as temporal differences (difference in mating seasons), habitat isolation, behavioural differences (different mating rituals such as different dance patterns, voice calls, et cetera), mechanical isolation, et cetera.

Thus, different breeding calls prevent the species to interbreed with each which ultimately prevent the formation of zygote formation.

Hence, it is a type of prezygotic isolation.

How are clouds and fog related to precipitation?
Dominik [7]

Answer and Explanation:

Both clouds and fog are closely related to precipitation.

This can be explained first by the formation of clouds and fog, which begin when the air contains water vapor. This <u>water vapor is produced when there is an accumulation of moisture in the enviroment which leads to the formation of clouds. A similar process occurs with the formation of fog, which comes from saturation, that occurs after the evaporation and condensation processes that take place after precipitation (water cycle). </u>

Moreover, some types of clouds (cumulonimbus) are associated with precipitation as they could be accompanied by climatic phenomenon such as rain and snow.

Temperature and minerals in the soil are abiotic, meaning they will never live.

Defend the statement found in controversy that foods, not supplements are the best and safest form of phytochemicals.
Anika [276]

Answer:

The easiest argument is the next one:

Suppose phytochemicals are like money. If I put you in a phone cabin with a lot of money and give you 30 sec to be there collecting as much money as you can, at the end you will collect not all the money and a lot of money will be lost. The same happens whit phytochemicals in supplements there are so many that your body can't use them all.

And other thing is that phytochemicals in supplements comes so concentrated that your body will be overstimulated to take this phytochemicals and that changes your normal digestion, in the time it may looks good...but if you don't take supplements anymore, your body will feel the lost and the physical results would be awull.
