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 how a karyogram is createdExplain how nondisjunction leads to disorders in chromosome numberCompare disorders caused by aneuploidyDescribe how errors in chromosome structure occur through inversions and translocations

By the end of this section, you will be able to:Define water potential and explain how it is influenced by solutes, pressure, gravity, and the matric potentialDescribe how water potential, evapotranspiration, and stomatal regulation influence how water is transported in plantsExplain how photosynthates are transported in plants

Students learn the basics about soil, including its formation, characteristics and importance. They are also introduced to soil profiles and how engineers conduct site investigations to learn about soil quality for development, contamination transport, and assessing the general environmental health of an area.

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:

"Sponges are key ecosystem engineers in many aquatic habitats. Their unrivalled ability as filter feeders allows them to capture and transform organic and inorganic nutrients, and their rich microbial communities have a metabolic repertoire that helps them transform habitats. To better understand how sponge hosts and their microbial symbionts work together to eat and drink particulate and dissolved food, researchers used specialized imaging techniques to visualize the uptake and translocation of isotope-labeled dissolved and particulate organic matter. Using two different sponge species with high vs. low microbial abundance, they found that both sponges showed enrichment of the labeled food over time. Sponge-associated microbes were actively involved in processing dissolved organic matter, but host filtering cells were the primary site of nutrient uptake – dissolved matter via pinocytosis and particulate matter via phagocytosis..."
