Answer:
True
Explanation:
because Ganglia were the evolutionary precursor to the centralized concentration of neurons that we now call a brain.
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 elimination rate constant (usually a first-order rate constant) represents the fraction of xenobiotics that is eliminated from the body during a given period of time.
For instance, when the value of the elimination rate constant of a xenobiotic is 0.25 per hour, this means that ∼25% of the amount remaining in the body is excreted each hour. The rate constant is calculated from the slope (−k/2.303) of the blood concentration and time curve (log–linear scale).

Answer:
The finding that suggests to the nurse that the lesion is in the right cerebral hemisphere is the Left-sided facial droop
Explanation:
At the level of the spinal bulb there is a point that is known as the decussation of the pyramid, where 80% of the axons that come from the right side of the brain intersect to the left side, and those that come from the left side, intersect to the right side, so the movements of one side of the body are controlled by the opposite side of the brain.
