The correct answer is D. Two species of insects produce infertile offspring

Explanation:

In biology, the prezygotic barrier refers to mechanisms or barriers that avoid different species to reproduce or that occur before a zygote is formed, this includes differences in the geographical location or ecosystem species reproduce, the time in which they reproduce, reproduction rituals, among others. Additionally, prezygotic barriers differ from postzygotic because postzygotic barriers occur after the zygote has formed and this mainly includes offspring that has lower viability or that is infertile. Considering this, the one that is not an example fo a prezygotic barrier is "Two species of insects produce infertile offspring" because different to the rest of the examples, this occurs after the zygote forms and therefore is a postzygotic barrier and not prezygotic.

If there was a fungicide that killed all fungi, make a prediction on how that would affect the ecosystem and eventually us human
marishachu [46]
Fungi is what decomposes things and puts nitrogen back into the ground. without the fungi plants would soon begin to run out of the nutrients they need. lack in vegetation would soon form. animals would then start to die of or migrate to different locations. so eventually you would begin to see less food and more wildlife in town because of the food shortage.

The passage states that organisms that live in fresh water cannot survive in salt water. These organisms will undergo a process
eduard

D) egg in Kayro syrup

Explanation:

An egg in Kayro syrup will experience plasmolysis. During the process of plasmolysis a body loses water to another one at a higher concentration. Fresh water organisms suffers plasmolysis because in salt water, the concentration of dissolved salt in the water is high and this makes the water hypertonic to their body.

  • In a hypertonic solution, the egg will lose water and begins to shrink in the Kayro syrup.
  • The Kayro syrup is hypertonic to the egg and by so doing, it will lose water to it.
