BIOL 211 Lecture Notes - Lecture 3: Meiosis, Primary Nutritional Groups, Prokaryote
Document Summary
Cyanobacteria, such as anabaena and stomatalites, are important because they created oxygen for aerobic organisms. Overly-hygienic conditions have eliminated beneficial microbes and leaves our immune systems under-stimulated. (you get rid of the good bacteria along with the bad) An example of a prokaryote/eukaryote partnership: our gut flora (termites) Gram + is more likely to be susceptible to penicillin (the thick layer means it"s more vulnerable) One thing you can do to slow antibiotic resistance is use antibiotics only when they are prescribed by a certified health professional. Complete the full treatment course, even if you feel better. Never share antibiotics with others or use leftover prescriptions, don"t use antibiotic soaps, create diversity in your gut. Prokaryotic divide by binary dission (produce two identical daughter cells) Divide by meiosis produce four genetically distinct haploid daughter cells. In humans meiosis results in eggs or sperm. The number of chromosome copies an individual has.
