The approximate capacity of the urinary bladder is

Correct Answer: C

Rationale: The urinary bladder holds about 600 ml at full capacity, though urge begins earlier. '600 ml,' is correct, per physiology texts like Guyton, varying (400-700 ml) by individual. '200 ml,' is minimal. '400 ml,' is functional but not maximum. '800 ml,' exceeds average. The 600 ml norm balances anatomy and function, making C the precise answer.

Correct Answer: D

Rationale: The epidermis has five layers, deepest to superficial: basale, spinosum, granulosum, lucidum, corneum. 'Stratum albicans,' is correct as the exception, a scar tissue term, per histology (e.g., Junqueira). 'Stratum basale,' regenerates. 'Stratum spinosum,' strengthens. 'Stratum corneum,' is outermost. Stratum albicans' irrelevance makes D the accurate answer.

Correct Answer: D

Rationale: Culture media support microbial growth. 'Sterile,' is correct as the exception, a condition, not a type, per microbiology (e.g., Murray). 'Selective,' favors specific organisms. 'Differential,' distinguishes species. 'Enriched,' boosts fastidious growth. Sterile's preparatory role makes D the precise answer.

Correct Answer: C

Rationale: Vector-borne diseases use insect carriers. 'Typhoid,' is correct as the exception, water/food-borne (Salmonella typhi), per infectious disease (e.g., Guerrant). 'Malaria,' (mosquito), 'Dengue,' (mosquito), and 'Yellow fever,' (mosquito) are vector-borne. Typhoid's transmission makes C the precise answer.
