The movement of water through a semipermeable membrane from a region of lower solute concentration to higher solute concentration is: MCQ with Answer and Explanation

The movement of water through a semipermeable membrane from a region of lower solute concentration to higher solute concentration is:
A. Active transport
B. Diffusion
C. Osmosis
D. Plasmolysis
Answer: Option C
Solution (By JKSSB Mock Tests)
Osmosis is the net diffusion of water across a selectively permeable membrane from a region of high water potential (low solute) to low water potential (high solute). Diffusion refers to solute movement, active transport uses energy, plasmolysis is cell shrinkage.

Question #1
Scurvy is characterized by bleeding gums and is caused by the deficiency of:
A. Vitamin B12
B. Vitamin C
C. Vitamin D
D. Vitamin A

Correct Answer: Option B


Explanation:
Scurvy is caused by a deficiency of Vitamin C (Ascorbic acid). Vitamin C is essential for the synthesis of collagen, a structural protein in connective tissues. Its deficiency leads to weakened blood vessels, causing symptoms like bleeding gums, loose teeth, joint pain, and poor wound healing. It was historically common among sailors lacking fresh fruits and vegetables.

National parks and wildlife sanctuaries are examples of which type of conservation?
A. In-situ conservation
B. Ex-situ conservation
C. Cryopreservation
D. Tissue culture

Correct Answer: Option A


Explanation:
In-situ (on-site) conservation involves the conservation of species in their natural habitats. National parks, wildlife sanctuaries, and biosphere reserves are examples of in-situ conservation. Ex-situ (off-site) conservation involves taking endangered species out of their natural habitat and placing them in special settings like zoological parks, botanical gardens, and seed banks for conservation and breeding.
