Explain the difference between prezygotic isolating mechanisms and postzygotic isolating mechanisms.
anastassius [24]
<h3><u>Answer and Explanation;</u></h3>
  • Prezygotic isolation is a type of reproductive isolation that occurs before the formation of a zygote can take place. In most cases mating does not even occur. Forms of prezygotic isolation include spatial, behavioral, mechanical and temporal isolation.
  • Postzygotic isolation on the other hand occurs after members of two different species have mated and produced a zygote. Forms of postzygotic isolation includes; hybrid sterility, hybrid inviability and hybrid breakdown.
  • Therefore; Prezygotic isolation prevents the fertilization of eggs while postzygotic isolation prevents the formation of fertile offspring.

Which of the following are some examples of rapid environmental changes? Please select all that apply.
Stolb23 [73]

Answer:

fire

landslide

avalanche

Explanation:

Fire, landslides, and avalanches are the examples of rapid environmental changes because they are able to destroy or affect the structure of living organism in a particular area. For example, fires can destroy all forms of life within days. A recent event of wildfire in Austria killed more than 1 billion of animals. Similarly, landslides and avalanche are geological calamities that are caused by the movement of a large mass of rock debris or snow moving downhill. The living organisms living there would be killed and this process can diminsh many forms of life (multicellular eukaryotes) rapidly.

On the other hand, (ecological) succession is a very slow process that results into change or disappearance of living organisms or particular species or ecological community in an area. This process can take place over decadaes, thousands or million of years. It can also lead to the species extinction as well.
