Question

1. the first law of thermodynamics and the law of conservation of matter are similar in that a) under normal circumstances neither energy nor matter is created not destroyed. c) both energy and matter are recycled through biological systems b) under normal circumstances energy and matter flow in a one - way path through biological systems d) under normal circumstances energy and matter are destroyed as they pass through biological systems. e) the first law of thermodynamics and the law of conservation of matter are not similar. 20) what implication(s) does the second law of thermodynamics have for biological systems? a) systems cannot create energy because energy is neither created nor destroyed b) with each transformation, less available energy is available to do work so older systems have less energy. c) a constant supply of energy is necessary for maintenance of biological systems. d) energy is unlimited because it is used and reused by living organisms. e) none of these is an implication of the second law of thermodynamics.

Explanation:

1. The first law of thermodynamics (law of conservation of matter and energy) states that energy and matter are neither created nor destroyed in normal circumstances in biological systems. Matter is recycled through biological systems, while energy flow is one - way. So the answer is C as both energy and matter follow these principles.
2. The second law of thermodynamics implies that with each transformation, less available energy is available to do work since some energy is lost as heat. So the answer is B.

Answer:

1. C. both energy and matter are neither created nor destroyed in normal circumstances in biological systems
2. B. With each transformation, less available energy is available to do work
