Answer:
25 mg / kg
Explanation:
The average weight of an adult is about 60 kg so if an adult has taken sodium chloride about 1,500 mg per day so each kg of the body needs only 25 mg of sodium chloride for fulfilling needs of the body and proper function of the body. So we can say that 60 kg body needs about 1500 mg of sodium chloride so for one kg of body weight, only 25 mg of sodium chloride is required.
Answer:
Dr. Reside's experiment can not be considered effective because his study has only treatment subjects group and lack of control group. That's why his study can be very good but not valid without control group.
In his study, he concluded that 80% children after therapeutic treatment decreased the activity level which can be true but not valid without control group because when he use control group in his study then we will be able to compare the normal or control group and treatment group. Then the study will be valid and effective as well.
