Answer:
True
Explanation:
<u>Rotational and linear motions are analogous to each other.</u>
<u>The inertia of a body in a linear motion is its mass.</u> This can be seen from Newton's second law of thermodynamics:
F = ma
The larger the value of the force, the larger the inertia is (m) and the slower it accelerates.
<u>The inertia of a body in a rotational body is it moment of inertia (I).</u> Both I and m are same but I depends on both the shape and mass of the rotating body.
For example, The inertia of a solid disk with mass M and radius R is:
Hence, the statement is true.
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.
True- an involuntary reflex is a reaction that happens when something else occurs. A involuntary reflex is something our body is “programmed” to do automatically.
