The Human Population: Factors that Affect Population Size

1. The Human Population: Factors that Affect Population Size

The human population is constantly changing. In this lesson, we will explore the factors that cause increases and decreases in the human population, including births, deaths, immigration, and emigration.

Global Population Issues, Concerns & Politics

2. Global Population Issues, Concerns & Politics

The following lesson will cover the issue of global population trends and the resulting concerns. We'll explore concepts like carrying capacity, how developed and developing countries differ, and how some cultures and governments affect this issue.

Senescence & the Biology of Aging

3. Senescence & the Biology of Aging

As people grow older, their bodies start to show signs of aging. In this lesson, we'll examine biological aging, also called senescence, including what it is, how it affects older adults, and what factors can affect how people age.

Global Trends in an Aging Population

4. Global Trends in an Aging Population

In this lesson we look at global trends that are occurring with the elderly, as well as specific issues that affect industrialized and developing nations. Lastly, we look at how culture is affected by all of this.

What is Biotechnology? - Definition, History & Examples

5. What is Biotechnology? - Definition, History & Examples

Biotechnology is a broad category and includes some surprising concepts. Learn what practices and disciplines fall under this exciting and expanding classification.

What is In Vitro Fertilization and How Does It Work?

6. What is In Vitro Fertilization and How Does It Work?

This lesson introduces the concept of fertilization, and then uses that background information to explain the details behind in vitro fertilization (or IVF). A summary and brief quiz are included at the lesson's conclusion.

What Is Amniocentesis? - Definition, Purpose, Procedure & Risks

7. What Is Amniocentesis? - Definition, Purpose, Procedure & Risks

Upon completion of this lesson, you will be able to define amniocentesis and describe how it is performed, its purpose, and potential risks involved. A short quiz follows the lesson.
