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.

Based on the scenario below, select the statement that accurately finishes the sentence.
Furkat [3]

Answer:

A. damaged her peripheral nervous system because the information regarding taste cannot be transmitted back to her brain.

Explanation:

The nervous system is an important system of our body and is directly related to our survival. This system is linked to the coordination of the organism's various activities and is also responsible for allowing the interpretation of the environment around us.

The nervous system is an important system of our body and allows us to have emotions, to remember an important moment in our lives, to interpret smells, tastes and images, to make movements and even to stay alive through the automatic breathing and heartbeat.

Taste, that is, the sense of taste is directly linked to the peripheral nervous system. For this reason, if Stacey has lost her sense of taste, we can conclude that she has damaged her peripheral nervous system because taste information cannot be transmitted back to her brain.
