The following are the types of nervous system and their functions.

1. Parasympathetic- functions as the relaxing response.

2. Sympathetic - functions as the flight and fight response.

3. Autonomic - it functions as the controller of automatic response.

4. Somatic- functions as controling voluntary response.

5. Peripheral- works as motor nerves and sensory which runs from and to central nervous system.

6. Central- works as the main interpretation and center of processing.

A scientist thinks that a certain chemical is a mutagen. She exposes plant cells to a large amount of this chemical in the labor

PSYCHO15rus [73]

A mutation is an alteration in the original DNA sequence. Option 3. The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.

<h3>What is a mutation?</h3>

A mutation is a stable and hereditably change in the genetic material.

Mutations alter DNI sequences and introduce new variants. Many of these variants are eliminated, but some of them might succeed and be incorporated in each individual, affecting the entire species.

They can be damaging or beneficial. These last mutations are the ones that have been selected by natural selection.

Different mutagenic agents cause changes in genetic information, increasing mutations over the normal level. They can change the bases sequences and bases pairing.

Mutations depend on each group's environment and its ecological pressures, and they accumulate in time. They are inherited to the followings generation and get to spread.

According to this framework, the correct option is 3. The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.

If the analyzed chemical is a mutagen, then it will cause an alteration in the DNA sequence and this change -mutation- will pass to the following generations spreading in the population.

Muscle tissues are characterized by the presence of elongated cells, often called ____________ , that can contract to create mov

PtichkaEL [24]

Answer:

1. Muscle Fibers

2. Bones

3. Joints

Explanation:

Muscle tissue is made of muscle fibers. The plasma membrane of a muscle fiber is called sarcolemma while its cytoplasm is known as sarcoplasm. Muscle cells are characterized by the presence of specialized endoplasmic reticulum which is called sarcoplasmic reticulum.

Muscle cells exhibit contractility and extensibility. The ability of muscle cells to shorten their length forcibly in response to a stimulus is their contractility. Muscle fibers have the ability to extend and shorten themselves.

Extension and contraction of muscle fibers are responsible for the movement of the human body and its parts.

Muscles are attached to bones via tendons which in turn are the fibrous connective tissues. Muscles are also part of our joints where they assist in the movement by pulling the bones as well as stabilize and strengthen the joints.

Manifestations of osteoarthritis include ( Select all that apply.) nodules on joints of the hands. crepitus with joint movement.

fiasKO [112]

Answer:

All options are correct, that is, they would all be correct for osteoarthritis.

This disease is characterized by being very painful at the joint level, it is degenerative, and mobility decreases over time.

Explanation:

Osteoarthritis is a pathology that is based on the fegenerative destruction of the joints, generating edema and loss of function, that is why it is pain.

The pain is very intense and very marked, that is why it is treated with immunosuppressive drugs and analgesics. (In addition to kinesiology and physiotherapy).

This disease decreases the functional unit and the joint space, generating possible ankylosis, pseudoarthrosis, elimination of lubricating fluid from joints and nodular structures. These nodular structures tend to be more common in the hands and are called by professionals as "drum fingers".
