Answer

Answer:

D. a closed system; energy is exchanged with the surroundings and not lost

Brief Explanations:

  1. Recall the definitions: An open system exchanges both matter and energy with its surroundings. A closed system does not exchange matter with its surroundings but can exchange energy.
  2. For human survival on Mars, the system (the habitat or the setup for survival) would need to be a closed system for matter (since we can't continuously get new air, water, food from Mars' environment easily in a sustainable way initially, so we need to recycle matter) but exchange energy (like getting energy from the Sun, or using energy for processes, and energy can be exchanged without losing matter).
  3. Analyze the options:
    • Option A: Open system with no matter/energy exchange is wrong (open systems exchange matter/energy).
    • Option B: Closed system with no matter/energy exchange is wrong (closed systems can exchange energy).
    • Option C: Open system with energy exchange but no matter loss is wrong (open systems exchange matter).
    • Option D: Closed system (no matter exchange) and energy exchange (which is allowed in closed systems) matches the requirement for a self - sustaining Mars habitat where matter is recycled and energy is exchanged (e.g., solar energy in, heat energy out).
