Answer:
The answer to the question: The movement of ions through their channels require a discharge of the capacitance, is, true.
Explanation:
In order for cells, muscular and neuronal, to perform their activities, they need to generate action potentials, that will permit these activities. In order for an action potential to happen, a cell´s membrance must be charged, or rather, its polarity must be changed, so that the cell can be charged and then fire. Usually, cells remain in a resting membrane state, in which, the extracellular matrix remains positive, while the intracellular space remains positive, due to ion, and anion presence in either. In order for the action potential to happen, these polarities are reversed through a series of steps in which ions, particularly potassium and sodium, sometimes calcium, will enter and exit the cell´s membrane to change this polarity. But in order for this process to take place, first a current, or stimulation, must motivate the cell to start the process. The capacitance is the capability of a cell to be ready to be activated or de-activated when stimulated, meaning, to be charged and discharged, when necessary. In order for this capacitance to permit the process of action potential formation, it needs to be discharged first, and this is done through the stimulus, which orders the cell´s membrane to initiate depolarization by opening up the ion channels. This is why the answer is true.
the correct spelling is option A.) Retinopathy the prefix is retin or retino
Answer:
The water-soluble vitamins comprises all the 8 B vitamins and vitamin C. When one consumes these vitamins, they get dissolved in water and then get mediated to various parts of the body via bloodstream. The body utilizes the vitamins it requires, and then the extra vitamin if got consumed is eliminated from the body via urine.
As the water-soluble vitamins are excreted time to time, one requires to meet the needs for water-soluble vitamins each day. The fat-soluble vitamins are vitamins A, E, D and K. When one consumes fat-soluble vitamins, they get dissolved in fat prior to getting mediated via the bloodstream.
The body utilizes the required fat-soluble vitamins and then accumulates any extra vitamins in the liver. However, if one consumes huge concentrations of fat-soluble vitamins spontaneously, then one may develop a condition known as vitamin toxicity or hypervitaminosis. The condition can be chronic or acute.
Answer:
that's so true. and the world is still sort of like that, since some people don't have health insurance and they still have to pay with cash up front
