At the onset of a muscle contraction, the presence of calcium triggers the opening of the Na-K channels in the membrane. Potassium is a calcium inhibitor, so as the potassium flows out of the cell, it eventually reduces the presence of calcium. This causes the closure of the Na-K channel (negative feedback mechanism). In a hypokalemic state, the lack of sufficient K doesn't inhibit the calcium channel, and in turn doesn't properly terminate the muscle contraction at the cellular level.
Answer:
First class lever
Explanation:
fulcrum is in the middle of the effort and the load. This type of lever is found in the neck when raising your head to head a football. The neck muscles provide the effort, the neck is the fulcrum, and the weight of the head is the load.

Answer:
In terms of medicine and biology, the word that means "normal function" is physiological.
Explanation:
Physiology is one of the areas of study of biology, where it describes how the normal functioning of cells, tissues, organs and systems should be, including the physical and chemical processes that occur in living beings.
The reference to a physiological state implies that all functions within a living organism occur as expected, with normality. It can be established that an organism in physiological conditions maintains its homeostasis. Physiological also serves as a reference to know when something is not working normally.
The other options are not related to normal processes and functions:
- <u><em>Proxy</em></u><em> is an intermediary or substitute for performing a function.</em>
- <u><em>Stereotype</em></u><em> has nothing to do with biological functions.</em>
- <u><em>Mediocre</em></u><em> means that something is not sufficient or adequate to be accepted.</em>
