What is the name for the process by which cells break down food molecules to release energy?

Correct Answer: A

Rationale: Respiration breaks down nutrients in cells to release energy, powering all functions. Unlike replication or division, it's the metabolic engine. Nurses address its disruptions like in COPD ensuring energy production sustains life's demands.

Correct Answer: C

Rationale: Fertilization unites egg and sperm into a zygote, launching development. Unlike division or diffusion, it's the reproductive spark. Clinicians monitor this in fertility, ensuring successful conception initiates life's cellular journey.

Correct Answer: A

Rationale: Hematopoiesis crafts blood cells in bone marrow, sustaining oxygen transport and immunity. Unlike clotting or breakdown, it's creation. Clinicians track it like in anemia ensuring blood supply meets bodily needs.

Correct Answer: B

Rationale: The cell is the basic unit of life, capable of all life processes (e.g., metabolism), unlike atoms (A, non-living), organs (C, multiple tissues), or tissues (D, cell groups). From single-celled organisms like bacteria to human neurons, cells are anatomy's starting point, housing organelles that sustain life, making B the clear answer.

Correct Answer: B

Rationale: Anatomical position is standing erect, arms at sides, toes forward, with palms facing forward (supinated), not backward. This standard posture ensures consistent directional terms like anterior across anatomy, and B's deviation (pronation) misaligns with this convention.
