Students hypothesize whether vinegar and ammonia-based glass cleaner are acids or bases. They create designs on index cards using these substances as invisible inks. After the index cards have dried, they apply red cabbage juice as an indicator to reveal the designs.

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:Compare and contrast the way in which aquatic animals and terrestrial animals can eliminate toxic ammonia from their systemsCompare the major byproduct of ammonia metabolism in vertebrate animals to that of birds, insects, and reptiles

Fundamentals of Ammonia Synthesis is a meticulously designed resource that was written to provide both students and educators with an amazing learning experience.The topic is structured into five captivating lessons, each carefully designed to understand the complexity of ammonia production. Beginning with the first lesson where we studied the process steps involved in ammonia synthesis, to lesson two where we explored the concept of Synthesis gas production by steam reforming with emphasis on natural gas reforming. In lesson three we analyzed the various operating variables that influence the production of synthesis. In lessons four and five we studied the purification of synthesis and how it is used for the production of ammonia. Each lesson comes with a quiz to reinforce what was learned.Our resource doesn't just serve as class notes; it's a gateway to a deeper understanding of chemical engineering principles. Whether you're a student seeking to grasp the fundamentals or an educator looking to enrich your teaching arsenal, "Fundamentals of Ammonia Synthesis" promises an enriching educational journey filled with insight, discovery, and practical application. Join us as we unlock the secrets of ammonia synthesis and pave the way for a brighter future in chemical engineering.

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:

"Nitrogen removal is a critical part of the wastewater treatment process. and one of the most efficient ways to remove nitrogen from water is anaerobic ammonium oxidation (anammox). Anammox is a process mediated by bacteria that — via several biochemical steps — converts ammonium to nitrogen gas. Understanding how external factors like nutrient availability impact these organisms can help us optimize and maintain these systems. A recent study found that the anammox bacterial communities are resilient to short-term starvation. The community structure changed slightly, and the bacteria increased expression of important nutrient transporters and energy metabolism genes. Expression of key genes associated with anammox reactions were also increased in response to starvation. The anammox bacteria showed fewer differences in transcriptional patterns after starvation than heterotrophs, suggesting that the anammox bacteria had greater transcriptional resilience than the heterotrophs..."
