Answer:

c. saltatory conduction  

Explanation:

An electrical impulse begins at the upper end of the neuron. This area is known as the axon ridge, and this ensures that the electrical impulse will travel in one direction only.

Through the myelin, the electrical impulse jumps from one node to another, instead of having to travel the entire distance from the axon. This type of signal conduction is called saltatory conduction.

Saltatory conduction speeds up impulse movement, as some axons may be up to one meter long. With this, the body achieves fast and efficient nerve conduction, and it is what allows you to react so quickly during reflexes.

What did you include in your response? Check all of the boxes that apply. The Abert's squirrel is found on the south rim of the
Serga [27]

Answer:

The completed question is

Two animals that can be found at the Grand Canyon include the Abert’s and Kaibab squirrels. The Abert’s squirrel is found at the south rim of the canyon and in a few surrounding states. The Kaibab squirrel, however, can only be found at the canyon’s north rim, mainly on the Kaibab Plateau. The Kaibab squirrel is not found anywhere else in the world. Scientists believe that the squirrels are actually closely related and have developed separately as a result of geographic isolation. It is possible that the squirrels were separated by plateau erosion that separated the forests and isolated the Kaibab population. Some scientists are studying if the squirrels are now two separate species or if the Kaibab squirrel is simply a subspecies of the Abert’s squirrel. Separate species are unable to reproduce with each other. Which evidence would be used to support the claim that the squirrels are two separate species?

a.The Abert’s squirrel is found at the south rim of the canyon, but the Kaibab squirrel is found at the north rim of the canyon.

b.Geologists prove that plateau erosion is the main cause of forest separation in the region.

c.Scientists observe that Abert’s squirrels are slightly larger and have bushier tails than Kaibab squirrels do.

d.When placed together in pairs for study, no pair of Abert’s squirrel and Kaibab squirrel result in offspring.

Explanation:

Base on the scenario been described in the question, the correct answer should be D.)When placed together in pairs for study, no pair of Abert’s squirrel and Kaibab squirrel result in offspring.
