Biology 101: Intro to Biology is designed to be used to prepare you to earn real college credit by passing the Biology CLEP exam . This course covers topics that are included on the exam, such as genetics, physiology, plant and animal biology, ecology and evolution. Use it to help you learn what you need to know about biology topics to succeed on the exam.

The biology instructors are experienced and knowledgeable educators who have put together comprehensive video lessons in categories ranging from Mendel's first law to the anatomy of the brain. Each category is broken down into smaller chapters that will cover topics more in-depth. These video lessons make learning fun and interesting. You get the aid of self-graded quizzes and practice tests to allow you to gauge how much you have learned.

Learn to differentiate between DNA and RNA and between mitosis and meiosis through Education Portal's chapter on basic genetics. Our team of professional educators, who have experience in biology, designed the video lessons in this chapter to be brief and easy to follow. You'll get an overview of genetics before exploring more complex topics, like DNA mutation and comparative genomics. Other topics covered in this chapter include cloning and genetic modification. To be sure you've mastered the material covered in each video lesson, you can take the accompanying self-assessment quiz. Biology 102: Basic Genetics can help you prepare for the Excelsior College Basic Genetics exam ; passing this exam can earn you actual college credit.

Get a basic overview of microbiology before exploring advanced topics like bacterial cell morphology, nitrogen fixation and protozoan diseases through this online Education Portal course, Biology 103: Microbiology. Watch our video lessons on STDs, bacterial diseases and foodborne illnesses as you prepare to earn real college credit through the Microbiology Excelsior Exam . Though the subjects covered in these lessons are somewhat intense, our experienced, knowledgeable instructors have kept the videos brief, engaging and easy to follow. You also can benefit from the multiple-choice quizzes and written transcripts that complement each video.

This lab course supplements BIO101 [1]: “Introduction to Molecular and Cellular Biology.”  Although we cannot virtually replicate a true lab experience, this “lab” will allow you to become familiar with scientific thinking and techniques and will enable you to explore of some key principles of molecular and cellular biology. The material in this lab supplement directly relates to the material covered in the lecture and reading portion of the course.  While the lecture and reading portion focuses on big-picture concepts, here we will focus more on visual understanding, manipulation, and practical use of your knowledge.  In each unit, you will work through tutorials related to important scientific concepts, and then will be asked to think creatively about how your knowledge can be put to practical or experimental use. There are also activities devoted to learning important techniques in scientific study, including microscope use, DNA extraction, Polymerase Chain Reaction, and DNA microarrays.  A…

In BIO101 [1], you were introduced to biology on a microscopic scale when you learned about the functions of molecules, genes, and cells.  In this course, you will learn about biological changes that happen on a very large scale, across entire populations of organisms and over the course of millions of years, in the form of evolution and ecology.  Evolution, the process by which different species of organisms have developed and diversified from their evolutionary forbears, has been a central theme in the field of biology ever since Darwin first published his theories about it.  Mounting evidence from many different branches of science all point to the fact that species have experienced a gradual but definite physical change.  In this course, we will learn about evolution and theories that stem from evolution. We will also learn about ecology, the study of the interactions between different types of organisms and their surroundings.  Changes in surroundings will force organisms to adapt and changeoften…

This lab course supplements BIO102: Introduction to Evolutionary Biology and Ecology [1].  Although we cannot virtually replicate a true lab experience, this “lab” will allow you to become familiar with scientific thinking and techniques, and will enable you to explore some key principles of evolutionary biology and ecology. The material in this lab supplement directly relates to the material covered in the lecture and reading portion of the course.  While the lecture and reading portion focuses on big-picture concepts, here we will focus more on visual understanding, application, and practical use of your knowledge.  In each unit, you will work through tutorials related to important scientific concepts and then will be asked to think creatively about how your knowledge can be put to practical or experimental use.

This course is designed to introduce you to the study of Calculus.  You will learn concrete applications of how calculus is used and, more importantly, why it works.  Calculus is not a new discipline; it has been around since the days of Archimedes.  However, Isaac Newton and Gottfried Leibniz, two 17th-century European mathematicians concurrently working on the same intellectual discovery hundreds of miles apart, were responsible for developing the field as we know it today.  This brings us to our first question, what is today's Calculus?  In its simplest terms, calculus is the study of functions, rates of change, and continuity.  While you may have cultivated a basic understanding of functions in previous math courses, in this course you will come to a more advanced understanding of their complexity, learning to take a closer look at their behaviors and nuances. In this course, we will address three major topics: limits, derivatives, and integrals, as well as study their respective foundations and a…

In this course, you will look at the properties behind the basic concepts of probability and statistics and focus on applications of statistical knowledge.  You will learn about how statistics and probability work together.  The subject of statistics involves the study of methods for collecting, summarizing, and interpreting data.  Statistics formalizes the process of making decisions, and this course is designed to help you use statistical literacy to make better decisions.  Note that this course has applications for the natural sciences, economics, computer science, finance, psychology, sociology, criminology, and many other fields. We read data in articles and reports every day.  After finishing this course, you should be comfortable evaluating an author's use of data.  You will be able to extract information from articles and display that information effectively.  You will also be able to understand the basics of how to draw statistical conclusions. This course will begin with descriptive statistic…
