  1. Green Revolution

  2. Golden Revolution

  3. Blue Revolution

  4. Yellow Revolution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Green Revolution in India was a period when agriculture in India increased its yields due to improved agronomic technology. Green Revolution allowed developing countries, like India, to overcome poor agricultural productivity. It started in India in the early 1960s and led to an increase in food grain production, especially in Punjab, Haryana and Uttar Pradesh during the early phase. The main development was higher-yielding varieties of wheat, which were developed by many scientists, including American agronomist Dr. Norman Borlaug, Indian geneticist M. S. Swaminathan, and others. The Indian Council of Agricultural Research also claims credit for enabling the Green Revolution, in part by developing rust resistant strains of wheat.

Multiple choice evs - i methods of preserving food food spoilage and food preservation food poisoning and food preservation methods food spoilage, adulteration and preservation

  1. Bacterial attack is minimised

  2. For easy cooking

  3. For easy digestion

  4. All the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Food products like fruits and vegetables are kept at low temperature to maintain its freshness, longevity and taste. Respiration uses stored starch and enhances ageing process. Low temperature minimizes the bacterial attack on food and also decreases respiration rate.

Thus, the correct answer is option A.

Which among the following is the most reason for storing green coloured apples at low temperatures?

  1. The rates of respiration and photosynthesis are reduced

  2. The rate of respiration is reduced

  3. The rate of photosynthesis is reduced

  4. Respiration and photosynthesis are completely inhibited
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

When green coloured apple are stored in low temperature the cellular proccess in the apples also gets reduced for conserving energy due to which the rate of respiration is reduced and the aging process is slowed down.

So, the correct answer is 'The rate of respiration is reduced'

B Correct answer
Explanation

i) Canned foods are boiled in the can to kill all the bacteria and seal the can to prevent any new bacteria from getting in.

ii)  Bacteria and fungi in the absence of moisture cannot grow rapidly as in the presence of moisture.
iii) The salt is a water absorbent. Hence, it removes water from any food as a result in the absence of water bacteria don't multiply and hence it acts as a preservative.
iv) Fruits, eggs, and meat can be stored for a long time at a very low temperature to avoid spoilage from microbes.
v) Use of oil and vinegar prevents spoilage of pickles because bacteria cannot live in such an environment. 
  • The correct answer is OPTION B.
