If you boil redbull will the caffeine evaporate or will the concentration of it in the resting redbull go higher?

Caffeine does not evaporate, hence the concentration will go higher.

Is the concentration of calcium ion greater in the sarcoplasmic reticulum or sarcoplasm of a resting muscle?
The Ca2+ ion concentration of the sarcoplasmic reticulum will be greater in a resting muscle
What is the mechanism that restores the resting membrane voltage and intracellular ionic concentration?
repolarization
What does the difference in the K and Na concentration on either side of the plasma membrane and permeability of the membrane to those ions generate?
resting membrane potential
A resting potential is caused by a difference in the concentration of certain ions inside and outside the cell?
True
Is resting potential caused by a difference in the concentration of certain ions inside and outside the cell?
True
Is the The resting membrane potential is mainly determined by the concentration gradient of K plus inside the cell?
Yes
When a resting nerve fiber is polarized sodium and potassium ions is higher on the inside of its membrane?
A resting nerve fiber is polarized because the concentration ofNa+ is higher on the outside and K+ is higher on the inside.
What would happen to the resting membrane potential of a neuron if sodium were allowed to travel freely down its concentration gradient?
The cell will depolarise
What does the difference in the K and Na concentration on either side of the plasma membrane (and permeability of the membrane to those ions) generate?
Resting membrane Potential
What would happen to a resting membrane potential if the concentration of a large intracellular anions that are unable to cross the membrane experimentally is increased?
If the concentration of large intracellular anions..i.e. proteins, which are unable to cross the membrane due to their large size.. were to increase, the resting potential would reach a more negative state, a deviation from -70mV to a more negative value do to these anions.
What will happen to a person's resting membrane potential if they take potassium enhanced intravenous solution?
A potassium enhanced intravenous solution would increase the concentration of potassium ions in the brain. Since potassium ions are positively charged, they depolarize the resting membrane potential. For example, a resting membrane potential of -65 millivolts would be depolarized to -62 millivolts. An appropriate concentration could lead to a significant depolarization of, say, -60 millivolts, at which point an action potential could be possible.
What are tips to reduce a rapid resting heart rate?
The Yoga Exercise is the best for gradually slowing down the resting heart rate. Reduce your stress, medical conditions, caffeine, alcohol, tobacco, and supplements then your heart rate gradually slow down and you’ll feel better.
