- Carrying capacity of a population
- Circadian rhythm
- Animal communication methods
- Biological influences on human behavior
1. Innate Behavior: Reflexes, Kineses and Taxes
When there is a loud sound, you quickly jump without thinking. This is because this reflex is an innate, or inherited, behavior. In this lesson, we will look at reflexes as well as several other types of innate behaviors.
2. Learned Behavior: Imprinting, Habituation and Conditioning
Ever wonder why it is easier to train your dog when you give him a treat every time he does something correct? In this lesson we will take a look at conditioning as well as several other forms of learned behavior.
3. Social Behavior: The Cost-Benefit of Altruism and Kin Selection
Ever wonder why people are more likely to help their relatives than complete strangers? Social behavior can help explain this and other actions. Let's look at the cost of certain behaviors.
4. Social Behavior: Agonistic, Dominance Hierarchies, & Territoriality
Instead of using words, animals communicate with each other through social behaviors. These actions between individuals may be used to establish rank, defend home and breeding sites, and compete for resources.
5. 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.
6. 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.
7. Carrying Capacity of a Population: Effect of Biomedical Progress
The human population continues to grow. There are several things that contribute to this growth, including biomedical progress. In this lesson, we will look at some examples as well as what may happen if this growth continues.
8. 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.
9. 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.
10. Biological Influences on Human Behavior: Genetics & Environment
Humans are a product of both our genetic makeup and our environmental surroundings. Does one influence our behavior more than the other? It can be difficult to tell, but there are ways that scientists can better understand why we do the things we do.
11. F1 Generation: Definition & Offspring
In this lesson, we will be discussing what the F1 generation is with regards to Mendelian genetics. We'll look at who discovered this F1 generation and how it is used to help us better understand inheritance as far as genes and traits are concerned.
12. Fixed Action Pattern: Definition & Examples
How do simple animals know what they need to accomplish? How do insects such as ants understand that they have to find food and bring it back to the nest? The answer: fixed action patterns.
13. Gastrulation in Humans and Other Mammals: Definition & Process
The development of humans and similar mammals follows a fairly close pattern. In this lesson, you'll learn about gastrulation, a process that readies developing humans and other mammals for the formation of organs and organ systems.
