21. A distance X km is covered by two different trains with velocity v (in km/hr) and kv (in km/hr) in y and y + 3 hours respectively.

If y < 13 then k is less than :

Correct Answer: (d) 13/16
Solution:D = S/T

Distance covered by both trains is same.

So, vxy = kv × (y + 3)

⇒ y = k(y + 3) (by putting y = 13 )

⇒ 13 = k(13 + 3)

⇒ k < 13/16

22. Animal cell wall is essentially made of :

Correct Answer: (c) Lipid bilayer
Solution:The animal cell wall is essentially made of a lipid bilayer, which is a biological membrane consisting of two lipid molecules. Each lipid membrane is made up of a hydrophobic head and a hydrophobic tail. It is a functional part of all cellular membranes. The cellular membrane is composed of lipoprotein and carbohydrates. Thus, option (c) is the correct answer.

24. Consider the following statements describing the functions of plants:

1. Photosynthesis is a process to convert light energy from the Sun into chemical energy i.e., Carbohydrates are synthesized from carbon dioxide and water using sun light

2. Fermentation or Zymology is a metabolic process that converts carbohydrate to alcohols and carbon dioxide

Which of the statements given above is/are correct?

Correct Answer: (c) Both 1 and 2
Solution:Photosynthesis is the process used by plants, algae and certain bacteria to convert light energy from sunlight and turn it into chemical energy, i.e. carbohydrates are synthesized from carbon dioxide and water using sunlight. Fermentation or Zymology is any metabolic process in which microorganisms' activity creates a desirable change in food and beverages, whether it's increasing flavour, preserving foodstuffs, providing health benefits, or more. Thus, both the options statements are correct and option (c) is the correct answer.
