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:Identify the new traits that first appear in tracheophytesDiscuss the importance of adaptations to life on landDescribe the classes of seedless tracheophytesDescribe the lifecycle of a fernExplain the role of seedless vascular plants in the ecosystem

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:

"Global urbanization is driving a flood of plastic pollution, and we desperately need ways to break these plastics down. And plastic-eating insects may be able to help. Such insects leverage their gut microbes to degrade plastic polymers, but little is known about how insects acquired this ability. To learn more, researchers examined the mealworm gut microbiome’s response to different diets. The bonds in synthetic plastic polymers can resemble those in natural polymers. Polystyrene, for example, has bonds like lignin, a polymer found in all vascular plants. So, the researchers fed mealworms polystyrene or corn straw, which is high in lignin. Neither experimental diet had a negative effect on the mealworms’ survival compared to a normal cabbage diet. Both polymer-heavy diets led to similar gut microbial community structures, metabolic pathways, and enzymatic profiles..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

In this activity, learners explore the question "What is paper?" Learners discover the processes and materials required to make paper while experimenting with different recycled fibers and tools.

Hank describes why plants are so freaking amazing - discussing their evolution, and how their cells are both similar to & different from animal cells.
