Ch 12: Adaptation & Regulation in Living Things

About This Chapter

Use these fun and engaging text and video lessons to review biology topics on adaptation and regulation as you prepare for an exam or just an upcoming biology class lesson. If you have questions about the material, our instructors are available to answer your questions.

Adaptation & Regulation in Living Things- Chapter Summary

These video and text lessons provide an engaging tool for students who want to learn more about adaptation and regulation. The lessons cover topics such as natural selection, biomimicry and osmoregulation. You'll learn the causes and treatment options for an overactive thyroid gland and see how diabetes impacts homeostasis of blood glucose levels. This chapter's lessons will enable you to:

  • Explore how natural selection affects adaptations to the environment
  • Provide examples of successful adaptations
  • Review the importance of the regulation of factors for a constant internal environment
  • Understand how the body communicates to make homeostasis possible
  • Discuss the challenges of osmoregulation
  • Recall how homeostasis is affected by diabetes
  • Explore the signs of hyperthyroidism

After reviewing the lessons in this chapter, you should feel more comfortable with these biology topics. You can also take the lesson quizzes to find out how well you retained the information in the lessons. There is also a chapter test that covers everything in the chapter. These tests link back to the lesson, making it simple to review topics you may have had trouble with.

Natural Selection & Adaptation: Definition, Theory & Examples

1. Natural Selection & Adaptation: Definition, Theory & Examples

How does natural selection help shape the amazing types of animals we witness around us? In this lesson, we'll explore adaptations and what they can tell us about a species' past evolution.

Homeostasis in the Human Body

2. Homeostasis in the Human Body

Homeostasis is the term we use to describe the reasonably stable internal environment of your body. Learn how parts of your body communicate with each other to maintain this state of homeostasis, and how negative feedback loops work.

Osmoregulation: Definition, Challenges & Energetics

3. Osmoregulation: Definition, Challenges & Energetics

Cells need a certain balance of water and solutes to survive, but this balance is different for different animals. Just as different is how animals regulate this balance, which you'll learn about in this video lesson.

Homeostasis of Glucose Levels: Hormonal Control and Diabetes

4. Homeostasis of Glucose Levels: Hormonal Control and Diabetes

In this lesson, we'll look at how the body uses hormones to maintain homeostasis of blood glucose levels, what happens in people who have diabetes, and how diabetics can manage their disease.

Hyperthyroidism:  Causes, Signs & Treatments

5. Hyperthyroidism: Causes, Signs & Treatments

The thyroid gland weighs only about half an ounce, but it drives the metabolism of every cell in our body. In this lesson we'll look at the effects of hyperthyroidism, in which the thyroid gland and its effects on our metabolism are kicked into overdrive.
