Proteins are extremely important to the human body. Which of the following is not a function of protein?

Correct Answer: D

Rationale: Proteins protect (A, antibodies), catalyze (B, enzymes), repair (C, collagen), but don't primarily insulate organs fat does, per anatomical roles. Options CB-C5 list protein functions, but insulation (adipose tissue) is distinct. Proteins build structure (e.g., keratin) and regulate (enzymes), not thermal insulation, making D incorrect.

Correct Answer: D

Rationale: Blood's matrix is plasma , the fluid portion, per options CD-C7. Cells (WBCs A, platelets B, RBCs C) are suspended in it. Anatomically, plasma (55% of blood) carries nutrients e.g., in anemia making plasma' a clearer term, confirming D.

Correct Answer: C

Rationale: Anatomy delves into the physical architecture of the body, examining bones, muscles, and organs to understand their arrangement. This exploration reveals how structures like the skeletal framework or vascular network are organized, providing a map for medical interventions. Distinct from psychological or fitness studies, anatomy's emphasis on tangible components such as the heart's chambers underpins surgical precision and diagnostic accuracy. It's a static snapshot of the body's blueprint, crucial for professionals navigating its complexity to maintain or restore health.

Correct Answer: B

Rationale: All living organisms exhibit growth, reproduction, and movement as fundamental traits, distinguishing them from inanimate objects. Growth reflects cellular expansion, reproduction ensures species continuity, and movement whether locomotion or internal shifts facilitates survival. These universal features, observable from bacteria to humans, underpin biological study, guiding scientists and healthcare workers in recognizing life's essentials across diverse forms, unlike human-specific abilities like speech.

Correct Answer: C

Rationale: Medial describes a position nearer the body's central axis, like the nose relative to the ears. This term contrasts with lateral, enhancing precision in anatomical descriptions. In clinical settings, it's crucial for localizing structures or conditions like medial knee pain facilitating targeted diagnostics and treatments by aligning with the body's symmetrical framework.
