I. INTRODUCTION Independent Study Questions 1.) What is the fundamental difference between eukaryotic and prokaryotic cells? Procaryotic cells do not contain a membrane-bound nucleus or any membrane-bound organelles. Eurkaryotic cells contain both a membrane mound nucleus and membrane-bound organelles (making them far more complex). 2.) List and describe the two domains of prokaryotic organisms. a. Bacteria- Most are a specific shape (cylindrical‚ spiral‚ or spherical). Cell

MICROBIOLOGY COURSEWORK The effect of antibiotic concentration on bacterial growth Introduction Null Hypothesis- Increasing the antibiotic concentration has no effect on bacterial growth. Experimental Hypothesis- Increasing the antibiotic concentration decreases bacterial growth. Scientific Theory Bacteria are prokaryotes and can be identified by their shape. Spherical bacteria are called cocci‚ rod shaped bacteria are called bacilli‚ spiral shaped bacteria are called spirilla and

Antibiotics use is as popular as ever with American people today. Every day over 190 million doses of antibiotics are administered in hospitals and more than 133 million antibiotic prescriptions are written out to non-hospitalized patients every year (4). These staggering numbers have made many skeptics question the effectiveness of these antibiotics and the frequency in which doctors prescribe them. Antibiotics are not a one stop cure for all illnesses. In fact‚ antibiotics are only effective

development of increased resistance to antibiotics is a global concern. According to WHO (2015)‚ antimicrobial resistance is an increasingly serious threat to global public health that requires action across all government sectors and society. Antibiotic resistance threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria‚ thereby resulting to loss of the ability to treat common infections. The development of antibiotic resistance is a natural phenomenon

Bio-112 Antibiotic Resistance Experiment Lab Partners: March 10‚ 2010 When we initially started the bacteria antibiotic experiment on February 10‚ 2010 our team selected e-coli and Rifampicin (Rb5) to find out the level of resistance e-coli would build towards this antibiotic. When we first checked our agar dish on February 15‚ 2010 we noticed two circles for the zone of inhibition the small circle was 1.5 cm and the medium circle was 3.00 cm. Two days later when we checked
