Questions: Question 8 (1 point) What is the correct SI unit for the measurement of Oxygen consumption; ml . kg^-1 . min^-1 kJ . kg^-1 . min^-1 J.kg ^-1 . min^-1 m / s . kg^-1 . min^-1

The answer is the first one: \(\mathrm{ml} \cdot \mathrm{kg}^{-1} \cdot \mathrm{min}^{-1}\).

Explanation for each option:

1. \(\mathrm{ml} \cdot \mathrm{kg}^{-1} \cdot \mathrm{min}^{-1}\): This is the correct unit for measuring oxygen consumption, often used in physiology and exercise science. It represents the volume of oxygen consumed per kilogram of body weight per minute.

2. \(\mathrm{kJ} \cdot \mathrm{kg}^{-1} \cdot \mathrm{min}^{-1}\): This unit represents energy expenditure rather than oxygen consumption. Kilojoules are a unit of energy, not volume.

3. \(\mathrm{J} \cdot \mathrm{kg}^{-1} \cdot \mathrm{min}^{-1}\): Similar to the previous option, this unit also represents energy expenditure, with joules being a unit of energy.

4. \(\mathrm{m} / \mathrm{s} \cdot \mathrm{kg}^{-1} \cdot \mathrm{min}^{-1}\): This unit is not relevant to oxygen consumption. It combines units of speed (meters per second) with mass and time, which does not relate to measuring oxygen volume.

In summary, the correct SI unit for the measurement of oxygen consumption is \(\mathrm{ml} \cdot \mathrm{kg}^{-1} \cdot \mathrm{min}^{-1}\).
