<em>The correct option is B) Scientific paradigm</em>
Explanation:
The scientific paradigm focuses on the infection and the microorganism for the occurrence of the infection. A scientific paradigm also refers to the treatment of these infections through pharmaceutical or surgical approaches. Hence, option B is correct.
Other options, like option A, is not correct because a holistic paradigm focuses on the connection between the mind, body and the soul. Option C is false because the analytical paradigm is not a part of the major health belief system.
Answer:
I, II, III
Explanation:
A threshold stimulus is a stimulus that is capable to produce a response in excitable tissues such as neurons and muscle fibers. At threshold potential, the outward movement of K+ and inward movement of Na+ become equal to each other. When the potential exceeds the threshold potential, more and more Na+ enter the cell to depolarize it and to allow the opening of Na+ channels. Therefore, to fire an action potential, the threshold must be exceeded.
Conduction of action potential is all or none phenomenon which means that either it occurs or it does not occur. As an impulse is passed by each successive part of an exon, it enters the refractory period during which there is no conduction of nerve impulse. It ensures the one-way conduction of impulse from the cell body to the axon terminal only.
Fish and marine mammals sift out the salt from the water, then they drink it.
