Radioactive tracer studies with `.^(14)C` have shown that

Radioactive tracer studies with 14_C have confirmed that

In an experiment in which photosynthesis is perforemd during the day. You provide a plant with radioactive carbon dioxide (.^(14)CO_(2)) as a metabolic tracer. The .^(14)C is incorporated first into oxaloacetic acid. The plant is best characterised as a

Highest pH (14) is shown by

If 5 g of a radioactive substance has t_(1//2) = 14 h, 10 g of the same substance will have t_(1//2) equal to

Why do we usually use isotopes emitting gamma radiations as radioactive tracers in medical science ? [Hint : gamma radiations are most penetrating]
