Question Discussion & Solution

• Vitamin is an organic non-protein substance that is required by an organism for normal metabolic function but cannot be synthesized in sufficient quantity by that organism. 
• These can be divided into two categories: fat-soluble and water-soluble.

Fat-Soluble vitamins

• Fat-soluble vitamins are soluble in fats.
• They are absorbed by fat globules that travel through the small intestines and into the general blood circulation within the body.
• Unlike water-soluble vitamins, fat-soluble vitamins are stored in the body when they are not in use.
• Vitamin A, D, E K are fat-soluble.

Water-soluble vitamins

• Water-soluble vitamins dissolve in water, which means these vitamins and nutrients dissolve quickly in the body.
• Unlike fat-soluble vitamins, water-soluble vitamins are carried to the body’s tissues, but the body cannot store them.
• Any excess amounts of water-soluble vitamins simply pass through the body
• Vitamin B and Vitamin C are water-soluble.

Key Points

Thus, the disease caused due to deficiency of Vitamin B1 is Beri Beri.

C = 3, L = 12, I = 9, M = 13, A = 1, X = 24

CLIMAX → 312913124

Similarly,

R = 18, E = 5, S = 19, I = 9, G = 7, N = 14

RESIGN → 185199714

Hence, “185199714” is the correct answer.

Hence, there is one such digit.

The correct answer is 7.

Key Points

• The pH value of salts of strong acid and strong base is 7.
  • The salts are from a strong acid and strong base do not hydrolyze and the resulting salt pH will remain 7.
  • The anion in the salt form's strong base does not attract the H+ from the water.

Additional Information

• Salt of a strong acid and a weak base is acidic with a pH value less than 7 because acid is strong which retains the pH value less than 7.
• Salt of a weak acid and strong base is basic with a pH value of more than 7 because the base is strong hence pH of the whole solution will be more than 7.
• Salt of a strong acid and strong base is neutral because both are strong and cancels strong effects of each other, the pH will be 7.

The study of the human mind is called Psychology.

Similarly,

the study of insects is called Entomology.

Hence, the correct answer is "Entomology".
