1. 1.

   In an orbital habitat, bioengineers study a synthetic organism, Metachroma, that rapidly constructs complex cellular polymers with remarkable efficiency. An apprentice observes Metachroma generating high order within its cells and hypothesizes that living systems can permanently decrease local entropy without dispersing energy into their surroundings. Which statement accurately explains how biological systems maintain structural order without violating the laws of thermodynamics?

   • A) Living organisms function as isolated systems that continuously convert metabolic waste heat back into ordered chemical bonds.
   • B) Organisms overcome the second law of thermodynamics by systematically destroying internal entropy once they achieve metabolic equilibrium.
   • C) Living cells generate new energy during anabolic reactions to offset the spontaneous increase in universal entropy.
   • D) Organisms act as open systems that couple macromolecular assembly with exergonic pathways, dissipating heat to increase the entropy of the surroundings.
