Bell performed experiments to show that nerves of the body contain a mixture of sensory and motor fibers.

In his experiment he tested if the two spinal roots that originally originated from spinal nerve carry signals in opposite direction to each other just prior to their joining at the spinal cord. The dorsal roots generally joined the spinal cord from the back while the ventral roots joined the spinal cord from the front.

He experimented on animals by cutting the ventral roots and noticed muscular paralysis, later with more observation came to the conclusion that the ventral roots carry signals back to the muscles and are motor in nature. While the dorsal roots are sensory in nature thus the nerves in the body are a mixture of sensory and motor nerves.

Papessa [141]

When the capture starts to increase, the fish population from 50 capture start to 100 capture start upsurges. At 200 capture start, though, the population augmented in the beginning up until it touched 300 months where it significantly dropped.

 

Numerous environmental factors can affect the populace of fish. First, when there is a hurricane, the fish population will be affected because the water will move and change.

Second, pollution. When individuals pollute the ocean, it affects the fishes’ ability to live.

Lastly, when there is a lot of hunters that feed on fish. This may cause many fishes to be consumed and their population will be reduced.

What is the best description of what viruses are made of?
Mazyrski [523]

The answer is C.

A virus is made up of or consists of a nucleic acid in varying quantity which may either be RNA or DNA.

The nucleic acid is surrounded by a protein shell called a capsid. The word capsid comes from the Latin word  capsa which means box.The capsid and the nucleic acid within it are together referred to as nucleoprotein.The  capsid is made up of small sub units called capsomeres.

In many viruses, the nucleoprotein makes up the whole virus. More complex viruses have one or more further enclosing structures also made mostly of protein. These structures are referred to as envelopes and each envelop is specific to a particular virus.
