Answer:
★ It is a process in which the top fertile layer of soil is lost. Due to soil erosion, the soil becomes less fertile. The top layer of soil is very light which is easily carried away by wind and water. The removal of topsoil by the natural forces is known as soil erosion.
Explanation:
Hope you have a great day :)
Answer:
Patient non-compliance
Explanation:
In this scenario, Mr. Bear was diagnosed with bronchitis and prescribed a two week course of antibiotics. After four days, he's feeling better, so he stops taking his antibiotic. This is an example of patient non-compliance.
A patient non-compliance can be defined as a situation where an individual who is diagnosed with an illness and prescribed with a medication refuses to take his or her medication. This refusal to comply with the prescribed medication is generally considered to be a wrongful act and is most likely to have an adverse effect or consequences on the health of a patient, as the illness may reoccur in the nearest future or result in a relapse.
Hence, medical professionals usually advise that patient strictly adhere to the instructions given to them rather than non-compliance.
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.
