Answer:

a prezygotic barrier

Explanation:

Both wild tigers and lions are said to be reproductively isolated.

Reproductive isolation is defined as the existence of barrier between organisms of different species such that they cannot reproduce.

The mechanisms of reproductive isolation varies. While some act to prevent the formation of zygotes (in case of mating) between organisms of different species, some ensures that the resulting zygotes are invalid.

Reproductive isolation mechanisms that act to prevent fertilization and formation of zygotes are referred to as prezygotic mechanisms while those that ensure that invalid zygotes result (in case of successful fertilization) are referred to post zygotic mechanisms.

<em>The natural differences in the ranges of wild tigers and lions ensure that both animals do not mate with each other, let alone results in zygote. This is a form of pre-zygotic reproductive isolation mechanism.</em>

Ne4ueva [31]

The way that neurons communicate is through synaptic vesicles which release neurotransmitters.

<h3>What are Neurons?</h3>

The neurons are the basic structural and functional unit of the nervous system.

These neurons are able to communicate to each other through the neurotransmitters that are released by synaptic vesicles.

The neurotransmitters are chemical messengers that carry chemical signals from one neuron to another upon the generation of an action potential.

The synaptic vesicles are the organelles that house these neurotransmitters.
