(a)
Interpretation:
Interpret the reason for the use of cobalt-57 for studying body’s requirement of vitamin B12.
Concept Introduction:
Majorly 99% of body mass composed of 6 elements such as oxygen, carbon, hydrogen, nitrogen, calcium and phosphorus while the 5 elements are present in 0.85 % of body.
The elements are required for proper functioning of body as some are requried as catalyst or some are required as oxidasing or reducing agent.
(b)
Interpretation:
Interpret the reason for the use of calcium-47 for studying the bone’s
