What would be the clearest demonstration of the flooding of jesse's potassium ions (k ) into the axions?
suter [353]

The clearest demonstration of the flooding of Jesse's potassium ions (K+) into the axons would be that Jesse stops running for a moment.

<h3>What is membrane potential?</h3>

The expression membrane potential refers to differences in the electrical charges in and out of the nerve cell (in this case, the neuron) in order to transmit information through prolongations called axons.

This difference is due to the presence of specialized ion channels in the membrane that allows the selective passage of ions to the interior of the cell or out it, thereby the movement of the potassium ions through axons is fundamental during the membrane potential.

In this case, stopping running would be caused by the K+ ions that flood the interior of the nerve cells, becoming them positive and leading to membrane depolarization.

In conclusion, the clearest demonstration of the flooding of Jesse's potassium ions (K+) into the axons would be that Jesse stops running for a moment.

Complete Question:

What would be the clearest demonstration of the flooding of Jesse's potassium ions (k ) into the axons?

A) Jesse is sleeping. B) Jesse is stretching before a run. C) Jesse is running as fast as he can. D) Jesse stops running for a moment.

kifflom [539]

Given: Drug medications are often prescribed on the basis of body mass. the adult dosages of elixophylin, a drug used to treat asthma, is 6mg/kg of body mass.

To find: The dosage amount for a person weighing 160 lb.

Method: Unitary method of proportions

Solution:

First we'll convert the weight of person from imperial unit to metric unit.

1 pound = 0.45 kilograms

160 pounds = 0.45 x 160 = 72 kg

∴ The weight of person in kilograms is 72 kg.

Now, a  elixophylin dosage of 6 mg is administered to 1 kg body mass.

For 72 kg body mass, dosage will be,

\frac{6 \times 72}{1} = 432 mg

∴ The person of 160 lb body weight will receive 432 mg of elixophylin dosage.

How do some people end up crazy and some of the things that make people crazy make others stronger
pantera1 [17]

Answer:

Everyone is raised differently, some people are used to handling certain situations better than others. For example, if someone is raised in an area with lots of sunlight and warm temperature and they decide to move to somewhere cloudy and cold when they grow up, the dramatic difference between temperatures could make this person 'crazy' and unable to adapt to simple situations in this climate, regardless of how easy it is to handle for others. This could be a metaphor for many situations.
