This site's sole function is to provide users with full conjugations of Arabic verbs. It allows users to select any three letter root from a pick a verb form (I-X) and then view a list of the verb conjugated for all pronouns in present and past tense, passive and active voice, and in all three Arabic verb cases.

This site has numerous brief, text tutorials on formal Arabic grammatical topics such as sentence structure, verb conjugation, and pronouns, as well as an extended section on the 10 most common verb forms. These tutorials usually favor transliteration over Arabic script.

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 the basic structure of a typical prokaryoteDescribe important differences in structure between Archaea and Bacteria

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:

"Horizontal gene transfer helps shape bacterial communities and drives the spread of antibiotic resistance. Of the three horizontal gene transfer pathways, conjugation has been studied the most in the context of antibiotic resistance. Antibiotics themselves can trigger these transfers, but the impact of other types of pharmaceuticals in natural environments remains to be explored. To close this gap, researchers examined several common non-antibiotic pharmaceuticals in a model of wastewater treatment plant activated sludge. The tested compounds covered multiple drug classes including an anticonvulsant, a lipid-lowering drug, a β-blocker, and nonsteroidal anti-inflammatory drugs. Environmentally relevant concentrations of the compounds promoted conjugative transfer of IncP1-α, a plasmid that carries antibiotic resistance. Exposure to these compounds spread IncP1-α across entire microbial communities..."

"Bile acids play key roles in gut metabolism, cell signaling, and microbiome composition regulation in mammals. Primary bile acids are produced from cholesterol in the liver but are modified by microbes in the gut to form numerous secondary and tertiary bile acids with diverse functions. For decades, gut microbes have been known to transform bile acids through several mechanisms, including deconjugation of the amino acids glycine and taurine by bile salt hydrolases, dehydroxylation of the cholesterol core, and dehydrogenation and epimerization of the cholesterol core. Notably, alterations in the chemistry of the resulting secondary bile acids are linked to several diseases, including cirrhosis, inflammatory bowel disease, and cancer. Recently, an additional transformation mechanism was uncovered in which gut microbes conjugate amino acids to bile acids. The discovery of the resulting microbially conjugated bile acids expands the known diversity of bile acids in the mammalian gut..."
