The reflex action is controlled by the: MCQ with Answer and Explanation

The reflex action is controlled by the:
A. Cerebrum
B. Cerebellum
C. Medulla oblongata
D. Spinal cord
Answer: Option D
Solution (By JKSSB Mock Tests)
Reflex actions are rapid, involuntary responses to stimuli, primarily coordinated by the spinal cord without immediate brain involvement. The reflex arc includes receptor, sensory neuron, interneuron (in spinal cord), motor neuron, and effector. The brain is later informed. Examples: withdrawal of hand on touching a hot object. The medulla controls autonomic functions like breathing. The cerebrum handles conscious thought, cerebellum coordination.

Question #2
The first antibiotic, Penicillin, was extracted from which microorganism?
A. Bacterium
B. Virus
C. Fungus (Penicillium notatum)
D. Actinomycete

Correct Answer: Option C


Explanation:
Penicillin, the first true antibiotic, was discovered by Alexander Fleming in 1928. He observed that a mold contaminating a Staphylococcus culture plate was inhibiting bacterial growth. The mold was identified as Penicillium notatum (now P. chrysogenum). Penicillin is extracted from this fungus and is effective against many Gram-positive bacteria.

Question #3
The vector commonly used for cloning genes in plants is:
A. pBR322
B. Cosmid
C. Bacteriophage lambda
D. Ti plasmid

Correct Answer: Option D


Explanation:
The Ti (tumor-inducing) plasmid from Agrobacterium tumefaciens is a natural plant genetic engineer. It transfers T-DNA into the plant genome, making it an effective vector for introducing foreign genes in plant genetic engineering. pBR322 is a common E. coli cloning vector. Bacteriophage lambda and cosmids are used in animal/bacterial systems. Ti plasmid has revolutionized GM crop development.
