question 17

Multiple Choice

Scenario
In some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called "ligers." Male ligers are sterile but some female ligers are fertile. In the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. Furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences.
-The natural differences in the ranges of wild tigers and lions is an example of ________.

• A)a prezygotic barrier
• B)a postzygotic barrier

Neuronal Networks

Complex webs of neurons interconnected through synapses, responsible for transmitting and processing information in the brain and nervous system.

Myelin Sheaths

Protective coverings around nerve fibers that increase the speed at which electrical impulses propagate along the nerve cells.

White Matter

Brain tissue composed of myelinated nerve fibers that connect different areas of the brain, facilitating communication among neurons.

Synapses

Structures that permit a neuron (nerve cell) to pass an electrical or chemical signal to another neuron, essential for the transmission of nerve impulses.
