Blood flows through an artery that is partially blocked. as the blood moves from the wider region into the narrow region, alternately increases and then decreases.

<h3>What is the purpose of blood flow in heart?</h3>

The removal of positive charge by electrochemical gradients causes the membrane potential of the cell to shift more strongly in the direction of the equilibrium potential for potassium.

The membrane would become more negative as potassium permeability through the membrane increased. Given that potassium is a positively-charged ion and that the intracellular environment has a net negative charge, enhancing the membrane's permeability would result in a more negative membrane.

For instance, the amplitude of the potassium concentration gradient across the myocyte decreases as the external potassium level rises, lowering the resting membrane potential.

What refrigerant safety group classification has the highest flammability and the highest toxicity?
timama [110]

Answer;

-B3

Explanation;

Refrigerants are divided into two groups according to toxicity:

-Class A signifies refrigerants for which toxicity has not been identified at concentrations less than or  equal to 400 ppm;  and

-Class B signifies refrigerants for which there is evidence of toxicity at concentrations below 400 ppm.

They are also divided into three groups according to flammability:

-Class 1 indicates refrigerants that do not show flame propagation when tested in air at 21°C and 101  kPa;

-Class 2 indicates refrigerants having a lower flammability limit of more than 0.10 kg/m3  at 21°C and  101 kPa and a heat of combustion of less than 19 kJ/kg;

-Class 3 indicates refrigerants that are highly flammable as defined by a lower flammability limit of less  than or equal to 0.10 kg/m3  at 21°C and 101 kPa or a heat of combustion greater than or equal to 19  kJ/kg.

-Therefore; the answer for the above question would be Class B and class 3.
