mariarad [96]

The intensity range would be 60-80%.

A high resting heart rate is indicative of an inefficient heart or possible arrhythmia. Physical activity assessments should begin after the client has been screened and resting measurements have been assessed.  Moderate intensity exercise uses energy 3 - 6 times that of resting metabolism, which equates to 3 -6 METs.

Students are studying the rate of yeast fermentation under different conditions. Glucose is a monosaccharide. Sucrose is a
Akimi4 [234]

Answer:

The correct option is B. Fermentation would occur at a similar rate to that of glucose.

Explanation:

Fermentation can be described as a process in which alcohol is released by using sugars. In fruit juices, fructose is present mainly to get the sweetness. It is used as a substitute for glucose because fructose is more sweeter than glucose. Both fructose and glucose are monosaccharides with the formula C6H12O6. The only difference is in the arrangement of molecules in the atoms of these compounds. Hence, the rate of fermentation would be same for these two sugars.
