25. A nerve fiber that conducts impulses toward muscles and glands is called a __________ fiber. A nerve that conducts impulses toward the brain and spinal cord is called a __________ fiber.

Answers

Answer:

A nerve fiber that conducts impulses toward muscles and glands is called a _____motor_____ fiber. A nerve that conducts impulses toward the brain and spinal cord is called a ______afferent____ fiber.

A nerve fiber that conducts impulses toward muscles and glands is called a motor neuron fiber. A nerve that conducts impulses toward the brain and spinal cord is called a sensory nerve fiber. Both are important for the proper functioning of the body.

What are sensory and motor nerve fibers?

The sensory nerve fibers send the stimulus in the form of an impulse from the sensory organs to the spinal cord, where the sensory organs can be skin, eyes, etc. An example is when a person sees a dog coming towards them, and the sensory nerve fiber that is associated with the eye sends the signal from the eye to the spinal cord. The spinal cord takes proper action by sending the motor nerve fibers to the effector organ, which is the leg muscle. In this case, the individual will run.

   

Hence, A nerve fiber that conducts impulses toward muscles and glands is called a motor neuron fiber. A nerve that conducts impulses toward the brain and spinal cord is called a sensory nerve fiber.

Water is wet because its viscosity is low.

What is viscosity?

Viscosity is a metric for a fluid's flow resistance. It speaks of the internal friction of a fluid in motion.

A fluid with high viscosity resists motion due of high internal friction caused by its molecular structure. Low viscosity fluids flow freely because their molecular structure causes little to no friction when they are in motion.

The thickness of a fluid is another name for viscosity. You can picture honey and low-viscosity water (high viscosity). However, when considering fluids with varying densities, this concept can be unclear. The interaction of the various molecules in a fluid results in viscosity at the molecular level.

Therefore, Water is wet because its viscosity is low.

From this discovery, scientists concluded that

Answers

We can confirm that scientists used this discovery to conclude that crocodiles evolved to be smaller over time.

Why would small size help Crocodiles?

Over time, many animals on the Earth evolved to smaller sizes. This made large predators unlikely to survive as they would need to hunt much more often than that of smaller predators in order to sustain themselves. This along with an increase in mobility explains some of the reasons why it was beneficial for crocodiles to evolve to be smaller over time.

Therefore, we can confirm that scientists used this discovery to conclude that crocodiles evolved to be smaller over time.
