An animal s behavior can help to maintain homeostasis, because many behaviors are responses to associations / stimuli that affect an animal s well-being. For example, if an animal gets too hot, it might move to a shady location. 6. Kinesis is an increase / decrease in random movement, and taxis is a movement in a random / particular direction. MAIN IDEA: Internal and external stimuli usually interact to trigger specific behaviors. Choose a word or words from the box below to complete the sentence. external internal hormones physiological 7. Some behaviors can be triggered by a single stimulus, but most behaviors occur in response to a variety of and stimuli. 8. An external stimulus, such as a change in day length, might cause an animal to secrete specific. 9. These hormones act as internal signals that cause other changes. These changes, in turn, cause the animal to be more likely to respond to another external stimulus. MAIN IDEA: Some behaviors occur in cycles. Fill in the blank with the word or phrase that best completes the sentence. 10. A circadian rhythm is a daily cycle of activity that occurs over a -hour period of time. 11. is a behavior in which an animal avoids extreme temperatures by entering into a dormant state. 12. is a behavior in which an animal moves from one location to another (often a long distance) to avoid harsh climate conditions. Vocabulary Check 13. The word circadian comes from a Latin word that means circle. A circadian rhythm is a circular pattern of activity, because it repeats every.
