describe the concentration of the intracellular fluid relative to the extracellular fluid in parts b and c. (figure 3-17)
○ isotonic to the extracellular fluid; hypotonic to the extracellular fluid
○ isotonic to the extracellular fluid; hypertonic to the extracellular fluid
○ hypertonic to the extracellular fluid; isotonic to the extracellular fluid
○ hypotonic to the extracellular fluid; hypertonic to the extracellular fluid
○ hypertonic to the extracellular fluid; hypotonic to the extracellular fluid

Explanation:

To solve this, we recall the concepts of tonicity: isotonic (same solute concentration), hypertonic (higher solute concentration), hypotonic (lower solute concentration). In typical scenarios for cell fluid tonicity (related to biology, specifically cell physiology), part b often represents an isotonic initial state, and part c (after some change, like cell in a solution) – if the cell's intracellular fluid has higher solute (hypertonic) relative to extracellular. The correct option is the one with "isotonic to the extracellular fluid; hypertonic to the extracellular fluid".

Answer:

B. isotonic to the extracellular fluid; hypertonic to the extracellular fluid
