These are sources of very good cavier. The beluga is actually a whale, while the osetra is a sturgeon. The sevruga is also a sturgeon.
Hey! I'm pretty sure this is chemistry instead of biology haha
But anyways, a typical carbon atom can form up to 4 covalent bonds!
Answer: positive sodium ions
Explanation:
This relates to the Action Potential which is what a nerve cell goes through when it needs to send information down the nerve cell to another cell and so on till it gets to the destination of the message.
The information is transmitted when the segments of the axon fire and when they do, positive sodium ions come in from outside the cell to the inside thereby making the inside positive. The previous segment would return to a resting potential when potassium ions which are negative, rush into the cell.
These ions bind to troponin, which forms a complex with tropomyosin. The process is called <span>Excitation-Contraction Coupling 3.</span>
It includes series of events, beginning with the production of an electrical impulse (action potential)<span> and ending with </span>contraction<span> of </span>muscles <span>in the </span>heart.
The nervous system's function is to process and respond to sensory information. The correct answer is C.
