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.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"The global carbon cycle is a critical process that moves carbon from the atmosphere into plant and animal materials and then back into the atmosphere. Two major parts of this cycle are microalgae blooms in the oceans and bacterial blooms that occur when the microalgae die. Microalgae are made mostly of polysaccharides, so polysaccharide breakdown is an important aspect of the bacterial blooms. To learn more bloom dynamics, researchers recently sampled the water at 30 time points during a two-phase spring bloom in the German Bight. They were able to reconstruct 251 genomes of planktonic bacteria, 50 of which were particularly abundant and active. These 50 genomes represented many polysaccharide-degrading bacteria. β-Glucans and α-glucans were the most abundant and actively metabolized polysaccharides in the water. The bacteria degraded both types of glucans throughout the whole bloom, but the expression of α-glucan degrading genes peaked at the start of the second phase..."

"Today, millions of people throughout the world lead richer, more productive and comfortable lives thanks to the thousands of chemicals poured into modern products and services. That makes the effective use and handling of chemicals and waste more important than ever. The United Nations’ 2030 Agenda for Sustainable Development outlines a plan of action for “preserving peace, people, prosperity, and our planet”. Central to that plan is the sound management of chemicals and waste, wherein reduction and renewable resources are key. Here’s where materials like cellulose play an important role. Cellulose is the most abundant natural polymer on earth, and one of the most in-demand. That’s because on top of being non-toxic and biodegradable, cellulose also tends to be lighter, cheaper, and stronger than other commercial polymers. There’s only one problem..."
