The correct answer is the Schwann's sheath (or the myelin sheath).

This sheath, made of Schwann cells, envelops the axons of peripheral nerves.

Named after the German physiologist Theodor Schwann, who discovered them, Schwann cells, or neurolemmocytes, are a form of peripheral glial cells. They, alongside oligodendrocytes, form myelin sheaths around neuron axons, which safeguards them and enhances the speed of nerve impulses.

lana [2441]
Work is defined as being completed when an object shifts as a result of an applied force. It is calculated by multiplying the force exerted by the distance moved as a result of that force. It can be represented as: W = Force x distance W = 84 J = F (7.0 m) F = 12 N I hope this provides clarity.

The model of exponential population growth predicts that the per capita population growth rate, r Select one:_______.
Tresset [2298]

Exponential Population Growth

Explanation:

The exponential population growth model forecasts that the per capita growth rate, r:

d. remains unchanged as the population enlarges.

A population is said to experience exponential growth when there are no constraints on its increase. All individuals have plentiful resources at their disposal, and the population showcases its inherent rate of growth. This is often termed geometric growth, where the rate of increase is reflected as a constant fraction or exponent applying to the entire population.

-BARSIC- [2551]
I believe the correct answer is D.
My reasoning for this conclusion is that coyotes from various groups would have encountered diseases and potentially developed immunity (for those that survived), allowing them to migrate to other coyote populations where those individuals may introduce the illness.
