Eating large amounts of meat will increase the levels of in the blood.

Correct Answer: C

Rationale: Meat (protein) raises blood urea from amino acid breakdown, not protein (intact), creatinine (muscle), or uric acid (purine). This identifies nitrogenous waste, vital for metabolism, contrasting with other markers.

Correct Answer: A

Rationale: Renal cortex is the outer layer, not inner (medulla), lateral, or medial (positional). This locates cortex, vital for glomeruli, contrasting with medullary depth.

Correct Answer: A

Rationale: Bowman's capsule is lined by simple squamous epithelium, not columnar, cuboidal, or stratified. This identifies capsule lining, vital for filtration, contrasting with thicker epithelia.

Correct Answer: A

Rationale: GFR is typically 125 mL/min, not 120, 130, or all. This standardizes filtration rate, vital for renal function, contrasting with approximations.

Correct Answer: D

Rationale: Adrenal gland (endocrine) isn't urinary, unlike urethra, bladder, ureter. This excludes non-urinary organs, vital for system definition, contrasting with excretory components.
