Answer:
The answer is C: motor end plate.
Explanation:
The region where somatic neurons join a skeletal muscle is known as a motor terminal plate. These plates are formed by an axon and a muscle fiber. Depolarization is produced by a nerve stimulation activating the corresponding muscle; Each muscle has its own motor plate and its corresponding axon.
Answer:
The smooth muscle is made up of a group of spindle-shaped cells, they do not have transverse striations, they are also known as non-wills and they will be found in the esophagus, intestine, stomach, uterus, blood vessels.
Collagen fibers are protein molecules that form fibers produced by connective tissue cells. They are found in 25% forming the skin and bones.
Answer:
The correct word to be fill in the blank is 'energy.'
Explanation:
Secondary active transport is a type of active transport, which involves transport of molecules or ions across the membrane against their concentration gradient by using energy.
In secondary active transport, energy is provided by electrochemical gradient. It involves transport of two molecules or ions (either in same or opposite direction) and required energy is generated due to difference in electrochemical gradient formed by pumping or ions across the cells.
An example of secondary transport is transport of potassium ions by K+/H+ exchanger that transports hydrogen ions and potassium ions in opposite direction. It uses energy from proton motive force (generated by transport of hydrogen ions or protons) to transport potassium ions.
Thus, the correct answer is 'energy.'
Answer:
What amino acids do is aid growth, cell replacement, and cell and tissue repair.
Explanation:
Amino acids are the units that make up the structure of proteins, necessary for the structure and function of living beings.
Due to the structural function of proteins —capable of forming tissues such as muscle and collagen that are present throughout the body— it can be said that <u>amino acids contribute to growth and development. In addition, amino acids and proteins can assist in cell renewal and repair of cells and tissues</u>.
The other options do not correspond to functions of the amino acids:
- <u><em>Help the body use certain vitamins and create cell energy </em></u><em>is a function of the lipids.
</em>
- <u><em>Provide energy and help cells get energy from other nutrients</em></u><em> is a function of carbohydrates.
</em>
- <u><em>Turn carbohydrates into proteins, fats, and fatty acids</em></u><em> is not a amino acid function.</em>
Answer:
It neutralizes the virus
Explanation:
When a vertebrate is infected with a virus, antibodies are produced against many epitopes on multiple virus proteins. A subset of these antibodies can block virus infection by a process that is called neutralization.
Antibodies can neutralize viral infectivity in a number of ways, as summarized in the illustration. They may interfere with virion binding to receptors, block uptake into cells, prevent uncoating of the genomes in endosomes, or cause aggregation of virus particles. Many enveloped viruses are lysed when antiviral antibodies and serum complement disrupt membranes.
