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.
Answer:
The function of the following tissues are as follows:
Stratified squamous keratinized epithelium: These tissues cover the surface of the body and present at hair and skin. These tissues are keratinized to protect the surface of body from abrasion.
Simple squamous epithelium: This tissue contain the single layer of flat cells. These tissues are thin and has the ability to pass some selected molecules through the cells.
Hyaline cartilage: Hyaline cartilage contains large amount of collagen that provides support and flexibility to the tissues.
Bone: Bones are made up of calcified material, phosphates and various inorganic ions. Bones provide stiffness and supports the weight of muscles in our body.
Answer: The total cholesterol is 199
Explanation:
Total cholesterol = LDL + HDL + Triglycerides
= 77 + 62 + 60
= 199.
As the patients doctor, I'd advise that the patient makes life style changes as they are approaching total cholesterol of 200 which is borderline high. Life style changes will include diet changes especially.
