Glucose is broken down through cellular respiration, which involves a large number of chemical reactions. At the end of the cellular respiration process, a large number of ATP molecules are generated, yet not all of the possible energy that is contained in a molecule of glucose can be harnessed through these chemical reactions to generate ATP. In other words, during cellular respiration, not all of the energy that is contained in a molecule of glucose is converted into the energy stored in ATP. The remaining energy is
A. lost as heat.
B. destroyed.
C. used to drive exergonic reactions.
D. donated to molecules in the cellular respiration process to reduce them.

Dr. Foster is studying the effectiveness of a new memory-boosting diet supplement. He posts an ad for subjects at two local colleges. He assigns 55 students from college A to the treatment group (daily doses of the diet supplement) and 60 students from college B (no supplement) to the control group. After 6 months of the study, Dr. Foster gives all of the students in each group a memory test. The treatment group scores an average of 20 points higher than the control group (a significant difference). Based on these findings, Dr. Foster declares that the memory-boosting supplement helps increase a person's memory. What would improve the design of the Dr. Foster's study?
A) Make the number of students in both groups the same. B) Randomly assign students to one of the two conditions (treatment or control). C) Administer the supplement for a longer period of time. D) Give the control group half the daily dosage of the diet supplement that the treatment group receives. E) Deprive the control group of sleep to see if that also affects memory recall.
Reinforcement is most likely to drive the evolution of
A. prezygotic isolating mechanisms because selection favors alleles that prevent hybridization. B. postzygotic isolating mechanisms because selection acts after the formation of hybrids. C. postzygotic isolating mechanisms because hybrids have low fitness relative to the parents. D. prezygotic isolating mechanisms because selection favors alleles that promote hybridization.
