Answer 1

1.what does potassium do to your body?

Potassium is a principal intercellular electrolyte which balances many functions of the body .potassium is present in the cardiac muscles which helps in the contractility of the myocardium.imbalance in potassium can lead to many arrhythmia

2.4700 mg/ day

The daily average intake of potassium for a healthy adult is between 3500-4700 mg per day.for patients with renal failure or on dialysis a low potassium of 2500 mg per day is preferred

3.h hydroxy pattite is a calcium is a crystal made of calcium and phosphorus.it is a very hard mineral it is used to make bone graft,dental prosthesis.

4.shellfish

Shellfishes like oyster,lobster has the highest amount of copper and they can provide the daily requirement of copper to an adult of about 10000mcg per day in one serving because the average copper in 3 ounce of oyster is 3600

5.glycogen stored can be restored by a high protein snack taken midway and 30 minutes post exercise because during workout the body burns glycogen stored in the muscles to generate energy so it's essential to replenish before the next workout.

6.By routine g the blood supply through the capillaries below the skin helps the sweat to evaporate and cool the body

7.dehydration

An athlete due to his strenuous physical activity looses water content from the body which leads to dehydration which can be restored only by providing water
