Multicellular Organisms, Tissues and Epithelium

1. Multicellular Organisms, Tissues and Epithelium

In this lesson on multicellular organisms, you'll take a look at what it actually means to be multicellular and how cells are organized into tissues, organs, and organ systems. This lesson also covers one of the four main tissue types: epithelial tissue.

DNA: Discovery, Facts, Structure & Function in Heredity

2. DNA: Discovery, Facts, Structure & Function in Heredity

This lesson will help you to navigate the twists and turns of DNA's structure. We'll also clue you in on the amazing discoveries that put this nucleic acid in the limelight as the molecule of heredity.

Using Feedback Systems to Regulate Growth, Reproduction & Dynamic Homeostasis

3. Using Feedback Systems to Regulate Growth, Reproduction & Dynamic Homeostasis

In order to maintain specific internal conditions, organisms use feedback mechanisms. Feedback is essential to the regulation of internal environments, which allows for proper biological functioning.

Positive and Negative Feedback in the Sympathetic and Parasympathetic Nervous System

4. Positive and Negative Feedback in the Sympathetic and Parasympathetic Nervous System

In this lesson, you'll study positive and negative feedback in the sympathetic and parasympathetic nervous systems. You'll also learn why we have a fight or flight instinct and how it works.

Structure & Function in Biological Organization: Benefits & Disadvantages

5. Structure & Function in Biological Organization: Benefits & Disadvantages

This lesson will discuss biological organization in terms of cells, tissues, organs, and organ systems. It will also discuss the benefits and disadvantages of multicellular versus single-celled organisms.
