C Correct answer
Explanation
  • White Revolution in India was a plan of three phases launched in 1970 by the National Dairy Development Board. 
  • Its aim was to increase India's dairy production until India became self-sufficient in milk. 
  • This program was highly successful and in 1998, India became the largest milk producer in the world. Thus the correct answer is option C.

Technologies break down various plant materials (for example, cellulose, lignin and xylan from crops) and it results in a

  1. Non-biodegradeable

  2. Less toxic

  3. Biomass

  4. Biofuel

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The productivity of plants as biofuel or biomaterial crops is established by both the yield of plant biomass per unit area of land and the efficiency of conversion of the biomass to biofuel. Genomics approaches support genetic selection strategies to deliver significant genetic improvement of plants as sources of biomass for biofuel manufacture. Genetic modification of plants provides a further range of options for improving the composition of biomass and for plant modifications to assist the fabrication of biofuels. The relative carbohydrate and lignin content influences the deconstruction of plant cell walls to biofuels. Key options for facilitating the deconstruction leading to higher monomeric sugar release from plants include increasing cellulose content, reducing cellulose crystallinity, and/or altering the amount or composition of noncellulosic polysaccharides or lignin. Modification of chemical linkages within and between these biomass components may improve the ease of deconstruction. Expression of enzymes in the plant may provide a cost-effective option for biochemical conversion to biofuel.

Therefore, the correct answer is option D.

D Correct answer
Explanation

Curing of tea leaves is accomplished by bacteria. Leaves of tea and tobacco are cured off their bitterness with the help of certain bacteria, e.g., Bacillus megatherium. Beans of coffee and cocoa are similarly cured.

A number of organic compounds can be decomposed by

  1. Pseudomonas

  2. Mycoplasma

  3. Chemolithotrophs

  4. Azotobacter

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Organic compounds like plant and animal residues are present in the soil. These organic compounds are broken down by a large number of bacteria, fungi, larger organisms. Bacteria like Pseudomonas lives in the soil and decomposes organic compounds and releases carbon dioxide, energy, water and other plant nutrients.

Thus, the correct answer is 'Pseudomonas.'

Which of the following have been more often used than any other group of plant substance n chemotaxonomic studies $2$?

  1. Falconoid

  2. Trapezoids

  3. Alkaloids

  4. Iridoids

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Flavonoids (misspelled as Falconoid) are secondary metabolites widely used in chemotaxonomy due to their diversity, stability, and distribution patterns across plant taxa. They serve as excellent chemical markers for classification and evolutionary studies.
