Closing the stomata for an extended period of time would lead to an increase in G3P in the mesophyll cells.
Answer the following statement true (T) or false (F)
False
While the stomata are closed, gases cannot be exchanged. As a consequence, oxygen levels rise and carbon dioxide levels decrease within the plant. Without carbon dioxide, the Calvin Cycle lacks the material to produce G3P, the precursor to glucose. Refer to section 36.4 for more information on stomata.

Imagine that you are talking with one of your friends. He states that evolution has actually violated the second law of thermodynamics because complex living organisms are more ordered than the nucleic acids, amino acids, and other molecules that compose them. Why doesn't evolution contradict the second law of thermodynamics?
a. Because evolution takes place over millions of years, the loss of entropy is negligible and thus the laws of thermodynamics are not violated. b. Evolution is a biological process, and biological processes do not have to conform to the laws of physics. c. Evolution doesn't affect entropy, as living organisms eventually die and become "disordered." d. Even though evolution may decrease the entropy of living organisms, it increases the entropy of the Earth (or the universe) as organisms release heat. e. Evolution actually does violate the second law of thermodynamics, and has been problematic for scientists.
The same hormone has considerably different effects in different species. The hormone thyroxine in humans stimulates metabolism, but in frogs it induces metamorphosis from tadpole to adult frog. This indicates that
A. metamorphosis is caused by a change in body metabolism. B. the chemical composition of the hormone is actually slightly different. C. the origin of the hormone makes a difference in the effect the hormone has on target tissues. D. the target tissues have evolved different responses. E. the organisms have absolutely no evolutionary relationship.
