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.
By the end of this section, you will be able to:Describe the role of cells in organismsCompare and contrast light microscopy and electron microscopySummarize cell theory
Throughout time, man has been curious about the world around him. As technology progresses, so too do the views of the scientific world. As we discover new ways to examine the world, we are forced to question our current theories and decide whether or not they are accurate or outdated. One invention, the microscope, was one of the most significant developments in scientific history. It allowed scientists a look at items so small they weren’t even believed to exist. From this invention stems the scientific theory of the cell. This activity allows students to explore the major players in the development of the cell theory.
In this visualization adapted from the University of Massachusetts Medical School, discover the role that dengue viral proteins play in a human cell as the virus prepares to replicate.
