(a)

Interpretation Introduction

Interpretation:

Whether carbon-13 is radioactive or stable has to be discussed.

Concept Introduction:

Isotopes are elements that have same atomic number but different mass number.

Radioisotopes are isotopes of an element having an unstable nucleus and dissipate energy in the form radiation in order to stabilize the nucleus.

(b)

Presence of various isotopes in food has to discussed based on the analysis of hair sample.

Concept Introduction:

Isotopes are elements that have same atomic number but different mass number.

Radioisotopes are isotopes of an element having an unstable nucleus and dissipate energy in the form radiation in order to stabilize the nucleus.

The relative abundance of various isotopes is affected by some physical and biochemical processes, such processes are called isotope fractionation.
