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 physiological effects of melatonin are far reaching, from acting as an neuroprotective agent to regulating circadian rhythms and sleep cycles. An imbalance of this hormone has even been linked to neurodegenerative diseases such as Parkinson’s, Alzheimer’s, and Huntington’s. The precise molecular mechanism by which melatonin exerts these effects, however, remains a mystery. To shed light on this process, a team of researchers has developed a melatonin-like compound that is unable to penetrate the cell membrane and binds only to cell-surface receptors. Melatonin’s physiological effects on the brain are controlled by the lock-and-key-like properties of this hormone and its receptors. When melatonin binds to its corresponding receptor, a biochemical signal is sent into the cell. But recent data suggests that this interaction may also occur inside the cell, itself. Specifically, on mitochondria within brain cells..."
The rest of the transcript, along with a link to the research itself, is available on the resource itself.

In this activity, students are divided into a group of hormones and a group of receptors. The hormones have to find their matching receptors, and the pair, once matched, perform a given action. This activity helps students learn about the specificity of hormone-receptor interactions within the endocrine system.
