The type of immunity resulting from the injection of ready-made antibodies is: MCQ with Answer and Explanation

The type of immunity resulting from the injection of ready-made antibodies is:
A. Active immunity
B. Cell-mediated immunity
C. Passive immunity
D. Innate immunity
Answer: Option C
Solution (By JKSSB Mock Tests)
Passive immunity is acquired by receiving pre-formed antibodies from another source, providing immediate but temporary protection. Examples: antivenom, immune globulin injections, and maternal antibodies. Active immunity is generated by the body's own immune system (infection or vaccination). Innate is non-specific, cell-mediated is T-cell based.

The technique used to separate DNA fragments based on size is:
A. Gel electrophoresis
B. Cloning
C. PCR
D. DNA sequencing

Correct Answer: Option A


Explanation:
Agarose gel electrophoresis separates DNA fragments by size under an electric field; smaller fragments migrate faster. PCR amplifies DNA, sequencing determines base order, cloning produces copies.

Question #2
The hormone that regulates the body's response to long-term stress is:
A. Thyroxine
B. Adrenaline
C. Cortisol
D. Insulin

Correct Answer: Option C


Explanation:
Cortisol, from the adrenal cortex, is a glucocorticoid that increases blood glucose, suppresses inflammation, and aids the body's adaptation to prolonged stress. Adrenaline is for acute stress, thyroxine metabolism, insulin glucose.

Question #3
The Fluid Mosaic Model of the cell membrane was proposed by which scientists?
A. Schleiden and Schwann
B. Robertson and Danielli
C. Singer and Nicolson
D. Watson and Crick

Correct Answer: Option C


Explanation:
The Fluid Mosaic Model of the plasma membrane was proposed by S. Jonathan Singer and Garth Nicolson in 1972. It describes the cell membrane as a dynamic, fluid structure composed of a phospholipid bilayer with globular proteins embedded or attached, moving laterally within the lipid matrix.
