A dynamic steady state results when A. a molecule stops being degraded. B. an organism is at equilibrium with its surroundings. C. there is no net energy transfer. D. the rate of intake or synthesis of a molecule equals the rate of its disappearance - Choice D is correct. A dynamic steady state results when the rate of synthesis or intake of a molecule equals the rate of its breakdown, consumption, or conversion into some other product. For example, a dynamic steady state in the blood ma...

Bio 198 Exam 5 KSU Questions and Answers Already Passed What is the first law of thermodynamics? And how does it pertain to cells? Energy cannot be created or destroyed Cells can't just create their own energy, they need a source. What is the second law of thermodynamics? And how does this pertain to cells? Energy is transferred, and in every transfer some energy is lost. Cells need a constant input of energy because they lose some as heat What is an endergonic reaction? A react...
