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:
One of the variables would be age and sex.
Explanation:
A person with disease with coromary disease, the first variable that would influence their genetic expression is age, and the second in my opinion would be sex, since the predisposition of certain diseases is different between both sexes, some are more frequent in women and others in men.
The age of a patient is a variable that must be taken into account in cardiovascular pathologies.
Answer:
1. biomedical equipment technician.
2. biomedical engineer.
3. blood and urine analysis equipment.
Explanation:
1. If a doctor needs help using a medical imaging machine, a biomedical equipment technician might be called to assist the doctor.
2. If a manufacturing company wants to develop a new biomedical machine, they might call on a biomedical engineer to help design and develop the product.
3. If you get a certification as a laboratory equipment specialist, you will specialize in the use of blood and urine analysis equipment.
Well Mitochondria are the structures within cells that produce energy. An example of mitochondria is what regulates metabolism in human cells.
Common signs and symptoms of preeclampsia include:
- Edema, hypertension, and headache.
<h3>What is preeclampsia?</h3>
Preeclampsia is a condition that occurs in pregnant women that causes high blood pressure in the mother and is accompanied by proteinuria.
<h3>Signs and symptoms of preeclampsia</h3>
- High blood pressure rises after about the 20th week of pregnancy, and stays high until the baby is born.
- Sudden swelling of the face, hands or feet (edema) together with a severe and persistent headache.
- In preeclampsia, there are problems with the placenta, which, together with hypertension, can reduce blood flow to the growing baby.
Therefore, we can conclude that preeclampsia is a condition that can develop during pregnancy, raises blood pressure, and can also affect the baby.
