Ch 24: Praxis Biology & General Science: What is a Living Thing?

About This Chapter

Let us teach you about viruses through the chapter What is a Living Thing? The video lessons and self-assessment quizzes in this chapter can help you correctly answer questions about diversity of life, plants and animals on the Praxis II: Biology and General Science test.

What is a Living Thing? - Chapter Summary

Explore the composition of viruses and learn about the history of virology - the study of viruses and the diseases they cause - through this chapter, which is designed as a study guide for the Praxis II: Biology and General Science test. Our instructors will introduce you to parts of a virus, including the capsid, nucleic acids and viral envelope, through this series of brief video lessons.

You'll also learn how viruses infect and replicate, in addition to examining the stages of the virus lifecycle: attachment, uncoating, penetration, replication and release. Finally, you'll come to understand how viruses are classified.

What is a Living Thing? Objectives

The Praxis II tests are used by the majority of U.S. states as part of their certification process for public high school teachers. The 120 multiple-choice-question biology and general science test must be completed within a 2-hour timeframe. Approximately 17% of the questions on this test focus on diversity of life, plants and animals; this might include questions on viruses.

To refresh your skills ahead of the Praxis II: Biology and General Science test, take advantage of the learning tools in this chapter. Each of the videos can be watched in less than ten minutes, and you can use our video timeline if you need to return to the main points for further clarification. Each lesson also includes a transcript of the video and a short self-assessment quiz. The latter can be used to measure your mastery of the presented information, as well as introduce you to the types of questions you'll encounter on the Praxis II.
