Answer: The false statement is “Warming up reduces the force a muscle contraction produces”.
Explanation: Warming up stimulates body’s cardiorespiratory and neuromuscular systems and metabolic energy pathways. During this process, muscles produce forceful and faster muscle contractions. To meet their increasing demands for oxygen, individual’s blood flow, heart rate, breathing rate and cardiac output increase. It occurs because blood moves faster through your veins and arteries and reaches to working muscles.
<span>1. Density is the mass of a substance divided by its volume. D= m/v
2.
To measure the volume of an irregular object you can fill a container with water and submerge the item. You would then measure the volume of water that was displaced by the obect.
3. D = m/v so m = 10.00 grams and v = 15.625 cm3
D= 10.00 grams/15.625 cm3 = 0.64 g/cm3</span>
