Answer:

increasing the number of hydrogen ions.

Explanation:

  • pH is a measure of the acidity or alkalinity of a solution.

<em>pH = -log[H⁺].</em>

  • The presence of H⁺ is the responsible of the acidity of the solution.
  • As the concentration of H⁺ increases, the acidity of the solution increases and so, pH decreases.

  • So, the right choice is: <em>increasing the number of hydrogen ions.</em>

What is the molarity of a solution made from dissolving 3.0 moles of NaCl in 250 mL of solution?
pentagon [3]

Answer:

Molarity = 12 M

Explanation:

Given data:

Molarity of solution = ?

Number of moles of NaCl = 3.0 mol

Volume of solution = 250 mL (250/1000 = 0.25 L)

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Molarity = 3.0 mol / 0.25 L

Molarity = 12 M

reddit The amount of NE released by sympathetic nerve terminals will be most strongly influenced by a change in which of the fol
erastovalidia [21]

Answer: Extracellular [Ca2+]

Explanation:

The sensitivity and density of the alpha receptors serve to <em>enhance the response to the release of</em> <em>norepinephrine (NE)</em> . However, they do not exert a strong influence as the concentration of calcium ions on the amount of <em>norepinephrine (NE)</em> released by sympathic nerve terminals.

The release of neurotransmitters depends more on either an external or internal stimulus.This results in an action potential which on reaching a nerve terminal, results in the opening of Ca²⁺ channels in the neuronal membrane. Because the extracellular concentration of Ca²⁺ is greater than the intracellular Ca²⁺ concentration, Ca²⁺ flows into the nerve terminal. This triggers a series of events that cause the vesicles containing <em>norepinephrine (NE)</em> to fuse with the plasma membrane and release <em>norepinephrine (NE)</em> into the synapse. The higher the action potential, the higher the Ca²⁺ flow into the terminals resulting in higher amount of <em>norepinephrine (NE)</em> into the synapse, and vice versa.

Catechol-O-methyltransferase (COMT) is one of several enzymes that degrade catecholamines such as dopamine, epinephrine, and norepinephrine. It serves a regulatory purpose to lower the concentration of norepinephrine upon its release from nerve terminals.
