Explanation: Weeds affect the growth of crops by competing with crop plants for water, space, nutrients, and sunlight. Thus, the crop yield is reduced. Thus, they provide shelter to them and promote plant diseases. Their seeds mix with the food grain and lower the quality of food grain yield.

3. Answer :  (d) Apis mellifera

Explanation: Apis mellifera ligustica is the Italian bee which is a subspecies of the western honey bee (Apis mellifera).

4. Answer : (d) Catlas

Explanation: Paper is made from wood, which is made up mainly of white cellulose. Wood also has a lot of a dark substance in it called lignin, which ends up in the paper, too, along with the cellulose. Newsprint, which must be produced as economically as possible, has more lignin in it than finer papers.

7. Answer :  (b) Milk production

Explanation: The revolution associated with a sharp increase in milk production in the country is called the White Revolution in India also known as Operation Flood.

8. Answer :  (b) Crop rotation

17. Answer :  (a) multipolar

Explanation: Multipolar neurons are the most common type of neuron. They are located in the central nervous system (brain and spinal cord) and in autonomic ganglia. Multipolar neurons have more than two processes emanating from the neuron cell body.

18.Answer :  (d) Hydrolytic enzymes

Explanation: Lysosomes are the reservoirs of hydrolytic enzymes. Lysosomes are also called scavengers of the cells. Note: Lysosomes have a role in transporting molecules within the cell. Lysosomes contain over 60 different enzymes that allow them to carry out these processes.

19. Answer : (d) Chloroplast

Explanation: Chloroplast releases oxygen in the Eukaryotic cells. It is a cell organelle that carries photosynthesis.

20. Answer :  (c) ATP

Explanation: Adenosine 5'-triphosphate, or ATP, is the principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank.
