Concept explainers
(a)
To determine:
The role of sunlight in promoting the bone maintenance and growth.
Introduction:
Sunlight is an essential component in growing children. The exposure to sunlight helps in formation of vitamin D3 which is very essential for formation of health bones, as vitamin D3 helps in absorption of calcium into bones. Lack of vitamin D3 can result in weakness of bones and muscles.
(b)
To determine:
The measures that can be taken to minimize the impaired formation of bones in children who reside in places with low exposure to sunlight.
Introduction:
Sunlight is an essential component in growing children. The exposure to sunlight helps in formation of vitamin D3 which is very essential for formation of health bones, as vitamin D3 helps in absorption of calcium into bones. Lack of vitamin D3 can result in weakness of bones and muscles.

What would be the protein needs of a man named Josh who exercises moderately and is the same age and size as Wayne? Josh is 5 ft, 8 in tall and weighs 183 lb. Round the number of grams to the nearest whole number. During calculations, use numbers rounded to the first decimal place. Because protein requirement is a range, please enter two numbers: lower and upper range values, respectively.
