Q: Pituitary gland is located in

A: brain

B: kidney

C: liver

D: intestine



Correct Option: A  [ brain ]

Q: The Bhopal Gas Tragedy was caused by :

A: Phosgen gas

B: Carbon monoxide

C: Methyl isocyanate

D: Chlorine



Correct Option: C  [ Methyl isocyanate ]

Remark:

Explanation: The Bhopal Gas Tragedy occurred on the night of December 2–3, 1984, at the Union Carbide pesticide plant in Bhopal, Madhya Pradesh (India). The disaster was caused by the accidental leakage of Methyl Isocyanate (MIC), a highly toxic and reactive gas used in pesticide manufacturing. The poisonous gas spread rapidly over the nearby populated areas, killing thousands of people and causing severe respiratory and neurological disorders. It is considered one of the world’s worst industrial disasters.


Q: Montreal Protocol is related to:

A: Ozone depletion

B: Bio-diversity

C: Biological weapons

D: European Community



Correct Option: A  [ Ozone depletion ]

Remark:

Explanation: The Montreal Protocol, signed in 1987, is an international agreement aimed at protecting the ozone layer by phasing out the production and use of ozone-depleting substances (ODS) such as chlorofluorocarbons (CFCs) and halons. It is one of the most successful environmental treaties in history.


Q: Gasoline is obtained from crude petroleum by:

A: Fractional distillation

B: Fractional distillation

C: Sublimation

D: Evaporation



Correct Option: A  [ Fractional distillation ]

Remark:


Q: Which polymer is used in making non-stick kitchen ware ?

A: Nylon

B: PVC

C: Bakelite

D: Teflon



Correct Option: D  [ Teflon ]

Remark:

Explanation: Teflon, also known as polytetrafluoroethylene (PTFE), is the polymer used in making non-stick kitchenware. It has a very low coefficient of friction and is resistant to heat and chemicals, which prevents food from sticking to cookware surfaces.


Q: Which of the following is a non metal that remains liquid at room temperature?

A: Phosphorous

B: Bromine

C: Chlorine

D: Helium



Correct Option: B  [ Bromine ]

Remark:


Q: The digested food is absorbed in

A: Stomach

B: Intestine (small)

C: Intestine (large)

D: Colon



Correct Option: B  [ Intestine (small) ]

Remark:

Explanation: The small intestine is the primary site of absorption of digested food. Its inner lining has numerous tiny finger-like projections called villi and microvilli that greatly increase the surface area for absorption. Nutrients such as glucose, amino acids, fatty acids, vitamins, and minerals pass into the blood and lymph through these structures. The large intestine mainly absorbs water and fo


Q: How much blood does a man have in his body?

A: 4 %

B: 10 %

C: 7 %

D: None of these



Correct Option: C  [ 7 % ]

Blood plays a vital role in transporting oxygen, nutrients, hormones, and waste products throughout the body. It also helps regulate temperature and maintain pH balance. The major components of blood are plasma (55%), red blood cells (RBCs), white blood cells (WBCs), and platelets.


Q: Onion is a modified form of

A: leaf

B: stem

C: root

D: None of these



Correct Option: B  [ stem ]

Remark:

Explanation: The onion is a modified underground stem called a bulb. It consists of a short, disc-like stem (the basal plate) surrounded by concentric fleshy leaf bases that store food. The roots emerge from the underside of the basal plate, and new shoots grow from the center. Thus, the onion bulb serves as a storage organ for nutrients and helps in vegetative propagation.
