问答题Experimental Effect Experimental effect is an interesting phenomenon that occurs when researchers perform experiments. The accuracy of the experimental outcome turns out just as hypothesized or expected -- not because of the knowledge or the methods of the researchers, but because their expectations tend to affect the processes and results of the experiment. For example, a researcher who predicts that the outcome of the experiment will not be the expected one may take actions that make the unexpected result more likely, thus fulfilling the original hypothesis. Question: The professor gives an example to illustrate the "experimental effect" phenomenon. Explain how this example is related to the reading passage.

问答题In this question, you will read a short passage, then listen to a lecture on the same topic, and then speak in response to a question about what you have read and heard. After you hear the question, you have 30 seconds to prepare your response and 60 seconds to speak. Read the following information from a textbook. HOMEOSTASIS Homeostasis is the tendency toward balance. In zoology, homeostasis is an animal's ability to maintain body equilibrium by adjusting its physiological processes. It is the body's continuous balancing and re-balancing of the processes that maintain stability and restore the body's normal state when it has been disturbed. Homeostatic systems keep an animal's internal environment within acceptable limits, even though the external environment may change. Homeostatic systems protect an animal's body from harmful changes, such as changes in temperature or water level.
