Answer:

Hypothesis

perceivable and measurable

Thinking critically

Introspection

Explanation:

A hypothesis acts as the premise or basis of experiment

It is like a guess that should return be proven right or wrong by the experiment

A scientific test must be perceivable and measurable such that it should be something that is tangible and can be measured such that it can be proven

Char is thinking critically by analysing facts to form judgement

Wilhelm is known as the father of experimental psychology and believed instrospection could be applied to reveal one's consciousness

Calculate the fractional saturation for hemoglobin when the partial pressure of oxygen is 72 mm Hgmm Hg. Assume hemoglobin is 50
kiruha [24]

Answer:

<em>0.964 or 96.4 %</em>

Explanation:

Hemoglobin is the red component of the red blood cell, it combines with oxygen to keep the body functional. The fractional saturation of hemoglobin is usually computed graphically but the hill equation gives a more specific value.

Calculations:

The hill equation can be expressed as;

Y_{O_{2} } =\frac{(P_{O_{2} })^{h}}{(P_{_{50} })^{h}+(P_{O_{2} })^{h}}

 Where Y_{O_{2} } is the fractional saturation of oxygen =?;

            P_{O_{2} } is the partial pressure of oxygen = 72 mm Hg;

           P_{_{50} is the partial pressure of oxygen when the hemoglobin is 50%    

                 saturated  = 24 mm Hg and;

            h is the Hill coefficient = 3.

Substituting the values into the expression above we have;

Y_{O_{2} } =\frac{(72 mm Hg_{_{} })^{3}}{(24 mm Hg_{_{} })^{3}+(72 mm Hg_{_{} })^{3}}

Y_{O_{2} } = \frac{373248}{13824 + 373248}

Y_{O_{2} }  = \frac{373248}{387072}

Y_{O_{2} } = 0.964

Therefore the fractional saturation is 0.964 or 96.4 %(multiply by 100)
