The movement of ions through their channels require a discharge of the capacitance.

Nesterboy [21]

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.

Thiamine (vitamin B1) deficiency diseases have a lower prevalence now than in the past. However, they are seen as beriberi in so

Misha Larkins [42]

Answer and Explanation:

Vitamin B (thiamine) is usually found in cereals, grains, vegetables and meat among other foods. Ingestion of this nutrient through balanced diet is one of the most important measures for the control of Beriberi. Not only the consumption of thiamine sources, but also the decrease in beverages that may disturb the absorption of thiamine, such as coffee and alcoholic beverages.

Beriberi is a serious disease directly linked to the lack of thiamine, also known as Vitamin B1. This disease can lead to death, but with proper treatment, it is possible to achieve cure. When vitamin B1 is not consumed regularly in food, mild symptoms of beriberi may arise such as insomnia, nervousness, irritation, fatigue, loss of appetite and energy. These problems may manifest themselves after two to three months of exclusively consuming thiamine-poor foods. Symptoms can still develop into more severe symptoms such as numbness, tingling and swelling of the legs and arms, difficulty breathing, heart problems, heart failure and even death.

Wernicke-Korsakoff syndrome), also known as alcoholic encephalopathy, cerebral beriberi, among others, is a neuropathy related to vitamin B1 deficiency, and indirectly (but more commonly) acute alcoholism, because alcohol interfere in body's ability to absorb thiamine.

Vitamin B1 is related to the process of transformation of pyruvic acid, which is responsible for performing biochemical transformations of proteins, fats and mainly carbohydrates. When this element is lacking in the body, neurons are the most affected cells, causing these sympthons above.

What percentage of native americans died from disease.

Kobotan [32]

Answer:

90%

Explanation:

When the Europeans arrived, carrying germs which thrived in dense, semi-urban populations, the indigenous people of the Americas were effectively doomed. They had never experienced smallpox, measles or flu before, and the viruses tore through the continent, killing an estimated 90% of Native Americans.

Explain why Balcetis and her team came up with the slogan, "Keep your eyes on the prize."

Lesechka [4]

Answer:

Balcetis explains that when people are in shape, they are more likely to view an exercise as achievable. More important than fitness, however, was individuals’ motivation to exercise. Those who were motivated to exercise saw a finish line as closer, than those who were unmotivated.

In a second study, Balcetis experimented with how changing one’s perspective on an exercise, can help to make it seem more doable. Balcetis presented a finish line at the end of a moderate sized path. Her control group looked around their settings as they normally would, and then estimated how far away the finish line was. The experimental group was instructed to look directly at the finish line and to try to eliminate other objects in their point of view. The results: the group that kept their eyes on the prize estimated the finish line to be thirty percent closer than those in the control group.

Last, Balcetis examined how perspective can help directly improve ease and efficiency. She had subjects try a moderately difficult exercise of walking a fair distance with weights. Again, one group kept their eyes on the finish line, while the other group proceeded normally. Those who focused on the finish line, felt that the exercise was fifteen percent easier than those in the control group. The focused group also moved twenty-three percent faster.

So what do all these findings mean? The way we look at exercise can make a big difference in how hard it feels and how hard we work at it. As Balcetis says, “keeping your eyes on the prize, may be an additional strategy you can use to promote a healthy lifestyle.” Well any strategy that makes exercise seem easier and gets me working harder, is one I’m definitely down for.
