r-selection:When parents don’t spend a lot or even any time caring for their young, they produce many offspring. This is a reproductive method used to make sure some offspring make it to the next generation. K-selection:Parents that put a lot of time and energy protecting and raising th...
She has a Bachelor of Science in Biology and a Master of Education. Cite this lesson This lesson provides teachers with a hands-on activity to teach students about natural selection and then uses a video to connect natural selection to antibiotic resistance. Students will practice new terms ...
Fresh plates or plates that are fresh out of a damp refrigerator can sometimes have asurface film of water that causes bacterial colonies to smear. To be sure that plates are dry leave them out at room temperature for one or a few days or place them in an incubator for a few hours or...

However, the majority of this work has not explicitly considered a crucial 46 feature of microbial ecology: microbes are typically embedded within complex communities 47 of interacting species. This is always the case within human and livestock microbiomes, in 48 which antibiotic-imposed selection is...
Changes in natural ecosystems, including the release of large amounts of antimicrobials, might alter the population dynamics of microorganisms, including selection of resistance, with consequences for human health that are difficult to predict. 展开 ...

Charles Darwin coined the term "natural selection." You'll typically hear it alongside the often misunderstood evolutionary catchphrase "survival of the fittest." But survival of the fittest isn't necessarily the bloody, tooth-and-claw battle for survival we tend to make it out to be (although...
These genes are subject to divergent selection and the arrangement of the genes on the genome in clusters is compatible with a high capacity for evolution of these genes so as to generate sequence diversity, new peptide structures and fusions with other proteins. Naturally, for the large majority...
