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

All living beings are made up of cells. Some of them are made up of only one cell and others have many cells. Also in: Dutch | French | Hungarian | Spanish

David Wolfe, Emeritus Professor of Physics, University of New Mexico, and Director, Oppenheimer Institute for Science and International Cooperation. Isaac Newton has a good claim to being the most famous man of the last 500 years. Whilst no individual can claim to be the originator of what has come to be called the Scientific Revolution, surely Isaac Newton is more responsible than any other single person. If we look at the technology on which our modern world is based - from the existence of electricity to transport to telecommunications and much else - all are based on the science which developed from the 18th century onwards. The Enlightenment, itself, and the concept of the individual, all developed as a result of his thinking. Even the reaction to these ideas from Romanticism to Fascism came about because of the rise of intellectual enquiry. Yet Newton does not fit the picture of 'the scientist' that we hold today. He spent more of his life thinking about alchemy and religion than he did about mathematics or physics. Moreover, he was one of history's greatest misanthropes. Left by his mother at three years of age, he appears never to have recovered from that trauma. This course will investigate Newton's life and work in relation to his achievements and also to his arguments with such people as Robert Hooke, John Flamsteed - the first Astronomer Royal, and Gottfried Leibniz- the codiscoverer of the calculus. An astounding genius, Newton was a deeply flawed human being.
