Answer 1

1).iron is an essential component of HEMOGLOBIN.it is a metal molecule for transporting oxygen to the parts of the body.

2).a deficiency of K could lead to increased blood pressure.when there is increased sodium in the diet potassium helps to neutralize the effect of the sodium.k helps in vaso dialation for lowering bp.

3).CA is most abundant in a typical diet.it is found in a large amount in a typical diet.

4).water has an extraordinary high SPECIFIC HEAT.water is having many hydrogen bonds and it is a polar molecule having low molar mass ,it is having the capacity to absorb energy.

5).K is not used for body structure.

6).an antinutrient tht inhibits the absorption if the iodine is an goitrogen.

7).phosphorus is an important component of ATP,tht is adenosine try phosphate.phosphorus is used as phosphate in the body.it helps in energy production.

8).water intoxication is similar to HYPONATREMIA.as for example a sport person when doing any race competition after the competition he can have water intoxication if he is taking enough water,extremely low level of sodium level rises in the body.
