Characteristics of Living Things

1. Characteristics of Living Things

Have you ever wondered what makes something alive? Learn more about the characteristics that classify something as living. These shared traits can be observed in all living things in the world around us.

Sexual Reproduction: Inheriting Genes from Each Parent

2. Sexual Reproduction: Inheriting Genes from Each Parent

Organisms reproduce in order to make offspring. With sexual reproduction the offspring get a combination of the genetic material from two parents. Learn how the male and female reproductive cells, called gametes, come together during fertilization.

Embryonic Development & Life Cycles of Invertebrates & Vertebrates

3. Embryonic Development & Life Cycles of Invertebrates & Vertebrates

In this lesson we will compare and contrast the embryonic development and life cycles of vertebrates and invertebrates. You'll learn how they are similar and how they are different, and view examples.

What is Nutrition?

4. What is Nutrition?

Nutrition is the process of taking in nutrients from the foods you eat. Learn about the six nutrients needed for energy, maintenance of tissues and regulation of bodily processes: carbohydrates, fats, proteins, water, vitamins and minerals.

What Is Homeostasis? - Definition & Examples

5. What Is Homeostasis? - Definition & Examples

Homeostasis can be defined as a property of an organism or system that helps it maintain its parameters within a normal range of values. It is key to life, and failures in homeostasis can lead to diseases like hypertension and diabetes.

Environmental Changes & Adaptation in Organisms

6. Environmental Changes & Adaptation in Organisms

In this lesson, we will discuss what happens when an organism is forced to deal with environmental changes. You will learn what adaptation is and how organisms benefit from it.
