Find out the incorrect statement from the following.

  1. White revolution was meant for increase in milk production

  2. Blue revolution was meant for increase in fish production

  3. Increasing food production without compromising with environmental quality is called sustainable agriculture

  4. None of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • None of the above statements are wrong. 
White Revolution or Operation Flood was started by Sir Verghese Kurien. It has created a milk grid which connected milk producers throughout India with consumers over 700 cities and towns. It helped the dairy farmers to have control of the resource created by them by reducing the regional and seasonal price variations and other malpractices like middlemen. White revolution's main objectives included: Increased milk production, an increase in rural income and fair price for the consumer.
Blue Revolution means a remarkable increase in the production of fish and marine products. It saw the emergence of aquaculture as one of the most important forms of agricultural activity. Aquaculture means all forms of active culture of animals and plants living in marine, brackish or freshwater. The Blue revolution was launched by Union Minister for agriculture Mr. RadhaMohan Singh. 
Sustainable agriculture - There is one sector that has continuously impacted the environment that sector is agriculture. For the human race to sustain there is a lot dependent on environment-friendly agriculture. We have been doing intensive agriculture, using loads of pesticides, chemical fertilizers and harming the environment. India is facing a food crisis due to the massive and regular destruction of farmlands. Therefore, sustainable agriculture focuses mainly on -
 a) To stop the usage of chemical fertilizers and give way to ecological means of cultivation thus preventing- the degradation of soil, food from toxins and carbon footprints.
b) to stop the promotion of genetically engineered crops as they pose a threat to human health and degrades the food quality.
Therefore all the above statements are correct.

Who is the pioneer of 'White revolution' in India?

  1. Swaminathan

  2. Verghese Kurien

  3. Dhiru Bhai Ambani

  4. S.K. Birla
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Verghese Kurien known as the 'Father of the White Revolution' in India,[2] was a social entrepreneur whose "billion-litre idea", Operation Flood, the world's largest agricultural dairy development programme, made dairy farming India's largest self-sustaining industry and the largest rural employment provider, being a third of all rural income, with benefits of raising incomes and credit, riddance of debt dependence, nutrition, education, health, gender parity and empowerment, breakdown of caste barriers and grassroots democracy and leadership. It made India the world's largest milk producer from a milk-deficient nation, which doubled milk available per person and increased milk output four-fold, in 30 years. A key invention at Amul, the world's first, was the production of milk powder from the abundant buffalo-milk, instead of from the conventional cow-milk, short in supply in India. Keen on a strong linkage between town and country, he surmounted skepticism and adversity with his indefatigable fighting spirit and outmaneuvering skills to capture a commanding share of the market of the city of Bombay (now, Mumbai), which got him wide attention.

So the correct option is 'Verghese Kurien'.

Which of the following statements holds good with pasteurization?

  1. Pasteurization removes all the bacteria from milk.

  2. Pasteurization is a synonym for sterilization.

  3. Milk needs to be refrigerated even after pasteurization.

  4. Pasteurized milk causes lactose intolerance.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

a) Pasteurization does not remove all bacteria from milk. It reduces the harmful active bacteria from the milk but it is unable to kill their spores which might erupt again under favourable conditions. 

b) Pasteurization is not a synonym for sterilization because of two processes are very different from each other when it comes to application. Pasteurization is the process where the milk is heated at to a specific temperature for a set period of time to reduce the bacterial population to prevent the spoilage and increase the shelf life. Sterilization kills all forms of living microorganism in the sample along with the spores of microorganism which cannot be done by the pasteurization.
c) Milk needs to be refrigerated even after pasteurization because refrigeration helps to keep the microorganism inactive for longer duration which increases the shelf life of the milk.
d) Pasteurized milk does not cause lactose intolerance because it does not affect or degrade the lactase enzyme which is responsible for lactose digestion in the humans.
So, the correct answer is 'Milk needs to be refrigerated even after pasteurization'.

The technique of developing pure culture of bacteria was developed by

  1. J. Lister

  2. L. Pasteur

  3. R. Koch

  4. A. V. Leeuwenhoek
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A pure culture is a laboratory culture containing a single species of microorganisms. A pure culture was usually derived from a mixed culture (culture containing many species of organisms) by transferring a small sample into a new, sterile growth medium. Robert Koch developed solid culture media and the methods for obtaining pure cultures of bacteria.

So, the correct answer is 'R. Koch'.

Which famous biologist propounded the 'germ theory of disease'?

  1. Joseph Lister

  2. Thomas Syndenham

  3. Robert Koch

  4. Louis Pasteur
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The more formal experiments on the relationship between germ and disease were conducted by Louis Pasteur between the year 1860 and 1864. He discovered the pathology of the puerperal fever and the pyrogenic vibrio in the blood, and suggested using boric acid to kill these microorganisms before and after confinement.

So, the corect option is D. ( Louis Pasteur)

Which of the following processes are used for increasing the shelf life of milk?

  1. Boiling

  2. Refrigerating

  3. Pasteurizing

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Boiling increases the temperature of milk and kills many bacteria and thus increases the shelf life of milk when compared to raw milk.
  • Refrigeration lowers the temperatures of the growth medium ( milk) making it not suitable for bacterial growth and keeps milk fresh for a particular period of time.
  • Pasteurization is heating milk to high temperatures and cooling down quickly. This process kills many possible pathogens and increases the shelf life of milk to a better extent. (1 day to 2 days)
  • So the correct answer is 'Boiling, Refrigerating, and Pasteurizing'.
