The fоllоwing questiоn cаme from the Mаstering Biology homework. Which of the following stаtements is consistent with the second law of thermodynamics? (a) A gain of free energy in a system is always associated with conversion of energy from one form to another.(b) Every energy transformation performed by an organism decreases the entropy of the universe.(c) Without an input of energy, the entropy of an organism would tend to decrease over time.(d) A constant input of energy is required to maintain the high level of cellular organization. Explain what is wrong with the statements made in (a), (b), and (c). (No, you do not need to know the second law of thermodynamics in order to explain what is wrong with these statements. Also, no points will be awarded if you merely state the opposite of the answer choice. You must demonstrate in your answer that you understand the material by adequately explaining what is wrong with the statements.)
