Answer 1

a)

1. Mr. X who used to smoke $3-4$ cigarettes every day will have more free radicals in his body. Cigarettes contain two types of free radicals

• one in the gas phase and
• the other in the tar phase.

2. Smoking cigarettes causes cancer because these free radicals which are most of the components of tobacco are oxidants that trigger a chemical reaction with oxygen in our body. As a result of such reactions, the by-products which are free radicals enter our bodies as we smoke cigarettes.

b)

3. Mr. Y who drinks three to four cups of green tea every day has adopted a healthy lifestyle because various anti-oxidants are present in the green tea which neutralizes the effect of harmful free radicals if present in our body. Green tea also helps in fat loss and it also protects our brain from aging.
