The right answer is C
This process is called anaerobic respiration. It doesn't need dioxygen to occur (it can happen with or without O2).
Anaerobic respiration is a mechanism in which electrons pass through a chain of transporters whose final acceptor is a mineral substance other than oxygen, unlike aerobic respiration where the final acceptor is dioxygen. The final acceptor may be the nitrate ion (as in the case of Pseudomonas), carbon dioxyde or the sulfate ion.
Some bacteria (Pseudomonas) are able, anaerobically, to reduce nitrates to nitrites and then, depending on the case, to dinitrogen (with the enzyme Nitrate reductase A).
NO3- ==> NO2- ==> N2.
Answer:
The correct answer is - The neuron's intracellular charge must get more positive to meet a certain thresh hold in order to depolarize. If the neuron does not hit that threshold, then the neuron will not fire
Explanation:
In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.
If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.
Answer:the nurse will tell the patient to stand in a comfortable position with the neck neutral of e little bit extended. The patient can also be told to sit down in a comfortable position with the neck neutral or little extended.
Explanation: the patient can also be told to swallow a sip of water as you the nurse palpate, feeling the upward movement of the thyroid gland
Answer:
The cell membrane is just like the other organelles of cells in that it serves the cell by having its own specialized jobs. One of its jobs is to control what enters and exits the cell and thereby to protect the cell.

The main function of the cell membrane is that regulates and monitors the movement of specific substances into and out of the cell, permitting only some substances to move across and not allowing others.
