Ch 14: Washington EOC Biology Grade 10: Biological Evolution

About This Chapter

When preparing for the Washington EOC grade 10 biology exam, you should study up on the subject of biological evolution. These lessons will teach you all of the information on this subject you will need to know.

Washington EOC Biology Grade 10: Biological Evolution- Chapter Summary

The Washington End-of-Course (EOC) Exam on grade 10 biology will include several questions on the subject of biological evolution. In order to do well on this part of the exam, you should go through these lessons for important information you will need. Each lesson will teach you about a different point related to the subject, such as:

  • The theory of evolution
  • Natural selection
  • The types of natural selection
  • Random mutations and genetic variability
  • Species diversity
  • Point mutations and protein functions
  • Mutagens and frameshift mutations
  • Artificial selection
  • The evidence for evolution
  • Organisms and evolutionary relationships

Our study guides will also allow you to test your understanding of these topics with some vital practice quizzes. You'll find the Washington EOC Exam much less daunting if you let us help you with your preparation!

Theories of Evolution: Lamarck vs. Darwin

1. Theories of Evolution: Lamarck vs. Darwin

We'll look at the interplay between population genetics and environment. Are traits individually acquired or do entire populations evolve? The flying hamsters and a few other notable experiments will provide the answers.

Natural Selection & Adaptation: Definition, Theory & Examples

2. 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.

Natural Selection: Definition, Types & Examples

3. Natural Selection: Definition, Types & Examples

We'll take a look at the types of natural selection that can occur. From flying hamsters to moths, you'll start to grasp the different paths organisms can take as they respond to their changing environments over time.

How Natural Selection Affects Populations

4. How Natural Selection Affects Populations

Varied genetic traits help species survive changes to their environment. This lesson will explain what happens in a population when one trait is favored over another due to environmental pressures.

Genetic Variability and Random Mutation

5. Genetic Variability and Random Mutation

Evolution is driven by variation among populations. The amount of variability determines how well a population can adapt to environmental changes, while random mutations can provide new variations that help a population adapt to unexpected changes.

What is a Point Mutation? - Definition, Causes & Types

6. What is a Point Mutation? - Definition, Causes & Types

What are genetic mutations? How do they affect our DNA? This lesson covers the basics of point mutations and provides simple examples of different mutation types.

Effects of Mutations on Protein Function: Missense, Nonsense, and Silent Mutations

7. Effects of Mutations on Protein Function: Missense, Nonsense, and Silent Mutations

How does a tiny point mutation change the way a protein works? What are the consequences of base substitutions? In this lesson, we'll use an imaginary creature to explore missense, nonsense and silent mutations.

Mutagens: How the Environment Affects Mutation Rates

8. Mutagens: How the Environment Affects Mutation Rates

What causes mutations to occur in living things? How do we avoid mutations? Are mutations always bad? Discover answers to these questions and more in this lesson on mutagens.

Effects of Frameshift Mutations: Definitions and Examples

9. Effects of Frameshift Mutations: Definitions and Examples

What is a frameshift in genetic translation? How can a frameshift mutation change a protein? In this lesson, learn about the codon reading frame and how frameshift mutations cause serious problems for polypeptide formation.

Genetic Variability, Random Mutation & Artificial Selection

10. Genetic Variability, Random Mutation & Artificial Selection

In this lesson we will discuss the importance of genetic variability and the role of random mutations. We will also compare the processes of natural and artificial selection.

What is Species Diversity? - Definition, Importance & Examples

11. What is Species Diversity? - Definition, Importance & Examples

Have you ever wondered how many species live on Earth? Earth is full of amazing creatures. In this lesson, you will learn about the importance of species diversity. At the end, test your knowledge with a quiz.

Evidence for Evolution: Paleontology, Biogeography, Embryology, Comparative Anatomy & Molecular Biology

12. Evidence for Evolution: Paleontology, Biogeography, Embryology, Comparative Anatomy & Molecular Biology

There is much support for the theory of evolution. This evidence comes from a variety of scientific fields and provides information that helps us trace changes in species over time. In this lesson, we'll look at this evidence and explore how it supports the theory of evolution.

The Evolutionary Relationships of Organisms

13. The Evolutionary Relationships of Organisms

In this lesson, we will discuss what evolutionary relationships mean, how we describe them, and how we determine them using morphological and molecular data. We will learn how the molecular clock determines our relationships by tracing random mutations.
