In the human body, the 'Basal ganglia' are a group of subcortical nuclei located deep within the cerebral hemispheres. They are primarily involved in:
A. Processing visual information
B. Regulating the sleep-wake cycle
C. Regulating voluntary motor movements, procedural learning, and habit formation
D. Controlling the endocrine system
Answer: Option C
Solution (By JKSSB Mock Tests)
The basal ganglia are a group of interconnected subcortical nuclei (including the caudate nucleus, putamen, globus pallidus, substantia nigra, and subthalamic nucleus) located deep within the white matter of the cerebral hemispheres. They are crucial components of the extrapyramidal motor system. Their primary functions are to regulate voluntary motor movements (by facilitating desired movements and inhibiting unwanted ones), procedural learning (learning by repetition), routine behaviors, and habit formation. Dysfunction of the basal ganglia leads to movement disorders like Parkinson's disease and Huntington's disease.

Question #1
In a dihybrid cross, the F₂ phenotypic ratio is:
A. 1:2:1
B. 3:1
C. 9:3:3:1
D. 1:1

Correct Answer: Option C


Explanation:
Mendel's dihybrid cross (e.g., yellow round × green wrinkled) gave a 9:3:3:1 phenotypic ratio in the F₂ generation, illustrating independent assortment.

Question #2
The fungus from which the antibiotic penicillin was originally extracted is:
A. Rhizopus stolonifer
B. Saccharomyces cerevisiae
C. Penicillium notatum
D. Aspergillus niger

Correct Answer: Option C


Explanation:
Alexander Fleming discovered penicillin in 1928 from the mold Penicillium notatum (later renamed P. chrysogenum). Aspergillus niger is used for citric acid production, Saccharomyces is yeast, Rhizopus is a bread mold. Penicillin was the first true antibiotic and its mass production during WWII saved countless lives. It inhibits bacterial cell wall synthesis.

Question #3
Consider the following statements about cell theory:
1. All living organisms are composed of cells.
2. The cell is the basic structural and functional unit of life.
3. All cells arise from pre-existing cells.
Which of the statements above are correct?
A. 1 and 3 only
B. 1, 2, and 3
C. 1 and 2 only
D. 2 and 3 only

Correct Answer: Option B


Explanation:
The modern cell theory includes all three statements: (1) all organisms are made of cells, (2) the cell is the basic unit of life, and (3) cells arise from pre-existing cells (Omnis cellula e cellula). Thus, all three are correct. This theory was formulated by Schleiden, Schwann, and Virchow.
