About This Chapter
TExES Life Science: Biology & Behavior - Chapter Summary
Utilize the educational video lessons in this chapter to review or learn more about innate and learned behaviors as well as social behaviors in humans and animals. You may reinforce your knowledge of fixed action patterns and increase your understanding of biological, inclusive and individual fitness. As you prepare to take the TExES Life Science examination, this chapter could assist you with:
- Understanding innate behaviors such as reflexes and kineses
- Explaining classical and operant conditioning
- Describing altruism and kin selection
- Discussing territoriality and dominance hierarchies
- Deciphering the caste system and the queen / worker relationship
- Identifying the stages of the theory of demographic transition
- Understanding the circadian rhythm
- Explaining the chemical and electrical signals through which animals communicate
- Discussing the life stages and traditions of families
While you get set to take the TExES Life Science examination, you could benefit from the opportunity for self-paced study as well as from the user-friendly videos themselves. The lessons are taught by instructors who have backgrounds in science. Ask questions if necessary, and study anywhere that offers a secure Internet connection. You may use the video tags to re-watch parts of the lessons or consult the transcripts that accompany the videos. Once you have watched each one, take the self-assessment quizzes to confirm your understanding of the material.
1. Innate & Learned Behavior
We all respond to different situations with some type of behavior. Some of these are innate and others are learned. This lesson will help differentiate between the two.
2. Social Behavior of Animals
Why does that squirrel flap its tail when your dog gets close to the tree? Or why are you more willing to donate a kidney to a sibling than a stranger? Learn about these and other behaviors that come along with living in a social group.
3. Social Systems vs. Individual Fitness: The Queen/Worker Relationship
The queen bee rules her hive while others take care of her needs. This form of behavior may seem odd, but it can be explained by looking into social systems and fitness.
4. The Theory of Demographic Transition: Overview
Populations change over time. The growth or decline of a population can have an effect on the quality of life for people within that population. In this lesson, you'll learn about the theory of demographic transition, which is a model used to study and predict population changes.
5. The Circadian Rhythm
You wake up in the morning and go to sleep at night. But some animals do the opposite: wake at night and sleep during the day. What determines the time of day you're active is your circadian rhythm, an internal clock that keeps daily time for you.
6. How Animals Communicate: Chemical, Visual & Electrical Signals
Animals use a variety of different signals to communicate with each other. In this lesson you'll identify the different types of communication signals and the situations in which they might be most useful.
7. Family Life Stages and Traditions: Courtship, Marriage, Child Rearing & Aging
In this lesson, we discuss the four stages of traditional family life that sociologists study. Although the concept of family has changed with time, these four stages remain prominent in our culture.
