Creating optimal conditions through engineering for a catalyst to act
Downstream processing technologies to purify the protein or organic compound
Upstream processing of all the activated antibodies and plasminogens in plant body
Which of the following cannot be a mean of increasing food production?
Agro-chemical based agriculture
Organic agriculture and
Genetically engineered crop-based agriculture
Inorganic chemical engineering
The Green revolution increased the food supply to
Triple fold
Double fold
Four fold
One and half fold
The partial reason of increased yield during green revolution was
Use of improved crop varieties
Use of better management practices
Use of agro-chemicals
Use of fertilisers and pesticides

They are expensive
Don't know how to use
Are not trained to use them
Of infertile soil
Which of the following is not a reason of less yield by farmers of developing countries?
Expensive agro-chemicals
Conventional breeding
Existing varieties
GMO
