1. The study of how disease or injury alters physiological processes is termed
A. Comparative physiology
B. The scientific method
C. Pathophysiology
D. Anatomy
2. Physiology
A. Emphasizes cause-and-effect mechanisms
B. Includes the fields of chemistry and psychology
C. Ignores the scientific method
D. Ultimately strives to understand the structures of individual cells
3. The term homeostasis is defined as the dynamic constancy of the internal
environment. True False
4. Negative feedback results in a response that opposes that of the original
stimulus. True False
5. Blood clotting is an example of positive feedback since the action of the
effector amplifies that of the stimulus.
True False
6. An integrating center of a negative feedback loop has the function of
analyzing information from many different sensors about deviations from a set
point and then altering the activity of particular effectors to compensate for the
deviation.
True False

True False
20. Hydrogen bonds form between the partially charged atoms of two polar
molecules, such as the slightly negatively charged hydrogen atom of one water
molecule and the slightly positively charged oxygen atom of another.
True False
21. Atoms sharing a pair of electrons form ionic bonds. True False
22. bonds are formed when atoms share electrons unequally.
A. Nonpolar covalent
B. Ionic
C. Polar covalent
D. van der Waals
