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 bacterial diseases that caused historically important plagues and epidemicsDescribe the link between biofilms and foodborne diseasesExplain how overuse of antibiotic may be creating “super bugs”Explain the importance of MRSA with respect to the problems of antibiotic resistance
This communication material is based on the findings of the study titled Probiotic as Alternative to Antibiotic in Broiler Diets of Jesus P. Cocal and Lilibeth A. Roxas (as cited in Gintong Saliksik: Multi-Disciplinary Research Journal of CNSC (Volume I No. 1, 2010)). This aims to simplify the presenation of the effects of antibiotic and probiotic on broiler chickens. It is written in Filipino because it is the mother-tongue of the intended audience who are poultry owners and farmers.
All of us have felt sick at some point in our lives. Many times, we find ourselves asking, "What is the quickest way that I can start to feel better?" During this two-lesson unit, students study that question and determine which form of medicine delivery (pill, liquid, injection/shot) offers the fastest relief. This challenge question serves as a real-world context for learning all about flow rates. Students study how long various prescription methods take to introduce chemicals into our blood streams, as well as use flow rate to determine how increasing a person's heart rate can theoretically make medicines work more quickly. Students are introduced to engineering devices that simulate what occurs during the distribution of antibiotic cells in the body.
Students are introduced to a challenge question. Towards answering the question, they generate ideas for what they need to know about medicines and how they move through our bodies, watch a few short videos to gain multiple perspectives, and then learn lecture material to obtain a basic understanding of how antibiotics kill bacteria in the human body. They learn why different forms of medicine (pill, liquid or shot) get into the blood stream at different speeds.
In this problem-based learning module, students will examine how natural selection is involved in the development of antibiotic resistant bacteria. They will evaluate methods to preventing antibiotic resistant bacteria from developing. Finally students will synthesize a plan to educate community members on preventing the development of antibiotic resistant bacteria.
