The movement of ions through their channels require a discharge of the capacitance.
Nesterboy [21]

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.

Serga [27]

Answer:

There is a low probability that a future pregnancy would exhibit similar phenotypes since it probably was a germinative line mutation that affected that egg.

Explanation:

The malformations of the unborn child, probably are due to a mutation in the germ cell of any or both parents. Germline mutations are detectable changes in a sperm or egg that we can see when the fetus is growing, as malformations since the original germ cell that was mutated divided itself to give more mutated cells for all the different parts of the fetus.

max2010maxim [7]

Answer:

4ml

Explanation:

80 × 0.25 = 20

Patient will need 20mg/day;

There are 50mg in 10ml, and we the patient needs 20mg so we can use ratios;

50 : 10

20 : x

20/50 = x/10

x = 4ml
