24. Which of the following antibiotics would you use to stop the growth of mycoplasma. A) Penicillin, an antibiotic that blocks cell wall biosynthesis. B) Tetracycline, an antibiotic that inhibits bacterial protein synthesis by blocking the function of ribosomes.
12. Breaking the Chain of Transmission of Infection Messaging about how to contain Covid-19 and reduce the spread of SARS-CoV-2 has changed dramatically since the first appearance of the disease in January of this year. Misinformation is rampant and the general public is often confused about the best way to proceed. Using your knowledge as a biologist, write an essay that explains to your friends and family how disease is spread and how each step promoted by the Centers for Disease Control helps to break the chain of transmission and flatten the curve. Include how each of the following techniques a) breaks the chain of transmission of disease, especially COVID-19; and b) the consequences to an individual and to society at large of failing to implement the technique. Wash your hands often, for at least 20 seconds. Don’t touch your face. Clean and disinfect surfaces. Wear a face covering in public Stay at least 6 feet from others. Stay at home.
