<span>The correct answer is: Oxygen

Explanation:
In order to function properly (movement etc.) during exercise, muscles require oxygen. During exercise, the depth as well as the rate of breathing increase, which in turn increases the amount of oxygen inhaled. In order to expand and contract lungs and for other bodily movements, muscles require oxygen, and for that, more oxygen is carried in the blood to muscles. Hence, the correct answer is Oxygen.</span>

MariettaO [177]

Answer:

The mechanical advantage of the pulley is 1.

Explanation:

The mechanical advantage of the pulley is given as

$MA=\frac{F}{f}$

Here, MA is represent for the mechanical advantage of the pulley, F is load for lift and f applied force.

Given F =21 N and f= 21 N.

Substitute the given values, we get

$MA=\frac{21N}{21N}$

MA = 1.

Thus, the mechanical advantage of the pulley is 1.
