oerc-1844 Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

The purpose of this task is to assess a student's ability to compute and interpret an expected value. Notice that interpreting expected value requires thinking in terms of a long-run average.

BioNetwork's Introduction to Lab Safety covers important considerations including: Proper Attire, PPE (Personal Protective Equipment, Safe Environment, Safety Equipment, Following Directions

Lyophilization, or freeze drying, is an important process to the biopharmaceutical industry. Operate a virtual lyophilizer and explore the process of freeze drying a product.

This online simulation gives you a chance to practice using an analytical balance and recording measurements in your lab notebook.

Culture media is a liquid or gel designed to support the growth of a variety of different types of organisms or cells. In this interactive eLearning tool, we'll practice preparing culture media by examining which area of the bathroom has the most germs.

Metric Conversions is an excellent tool for refreshing your knowledge of dimensional analysis, English-to-Metric, Metric-to-English, and Metric-to-Metric conversions.

Take a self-guided exploration of a common laboratory microscope including its care, components, and usge.

Learn about molarity through this interactive scenario where you will assume the role of a new TA working with Dr. Orville Catalisk.

Moles can be a little confusing, but BioNetwork's new eLearning course can help! In this exercise, you will play the role of a new intern at a commercial chemical company. Your job is to help various departments with their tasks, both inside and outside the lab. Along the way, you'll learn about moles and be able to apply your knowledge to challenging scenarios.

You've just been hired as a quality assurance inspector for a research testing company. Your job is to talk to employees in the aliquoting department and identify pipetting-related CAPA, Corrective and Preventative Actions that your company should take.

In science, it is not unusual for us to use either very large or very small numbers in our measurements and equations. Before the advent of calculators, we used scientific or exponential notation to simplify handling these very large or very small numbers.

Significant figures are a way of showing the precision of a number or group of numbers. Significant figures are important because they tell us how good the data we are using are. Significant figures are critical when reporting scientific data because they give the reader an idea of how well you could actually measure/report your data.

The purpose of this task is to have students compute and interpret an expected value, and then use the information provided by the expected value to make a decision. The task is designed to encourage students to communicate their findings in a non-technical form in context.

This interactive lesson covers the basics of Spectrophotometry including: a general overview of spectrophotometry, operation of a spectrophotometer, basic components, and common safety considerations.
