Scientists have discovered that people carry a staggering variety of bacteria on their hands. They found a total of 4,742 different species. Individual test subjects averaged 150 different types, with women averaging more types of bacteria than men. Scientists are not sure why but have offered several possible explanations. The difference may have something to do with acid on the skin. A man's skin generally has more acid than a woman's skin does, and bacteria do not thrive as well in more acidic environments. Another cause could be the differences in sweat and oil produced. Makeup use could also make a difference, as could skin thickness. Do It!

Bacteria help produce vitamins in our digestive system Bacteria help clean our intestinal walls and help digest food Bacteria are involved in the production of a variety of foods we consume All of the above are true Which of the following statements concerning viruses and human health is 1 false? in many diseases caused by viruses, the virus attacks cells as it reproduces many viral diseases can be controlled through vaccinations some viruses can remain dormant in the body for years before disease symptoms appear most viral infections are difficult to treat, but they can be finally destroyed by antibioticsIS IT A FACT OR A BLUFF? 1. Bacterial genetic material is composed single stranded DNA as compared to human DNA which is double stranded. 2. Just like humans, all microbes need oxygen to grow and reproduce. 3. There are no living microbes in volcanic vent and in hot spring because microbes die at very high temperature. 4. Most bacteria growth is retarded at low temperature. 5. Bacterial ATP production happens in the mitochondria which is the powerhouse of the cell. After identifying your answer whether fact or bluff, you need to give justification to your answer. You Justification should be given in not more that 50 words.
- Which of the following does not apply to superbugs? O It is estimated that 70% of antibiotics used in the USA are sold to animal farms. O The CDC reported that 1 million people in the U.S. may contract a superbug every year in the USA. O The CDC predicts that 35,000 people will die yearly from superbugs in the USA. By the year 2050, antibiotic resistant bacteria may kill as many as 10 million people in the world.I dont understand this practice Biology Question. In order to categorize bacteria, scientists use various characteristics to classify them into groups. Without naming these groups, explain characteristics and tests used by microbiologists to assign bacteria to different taxonomic groups.Hi i’m supposed to write a short essay on how evolution and microbiology relates to antibiotic resistance, but i don’t know where to start
- Vhich of the following does NOT describe a mechanism of antibiotic resistance among bacteria O enzymes to hydrolyze or chemically alter the antibiotics O efflux pumps Omutations in target moleclues so that antibiotics can no longer bind O increased synthesis of porins to increase antibiotic diffusion across membranes O cell wall diffusion barrier, e.g. Gram-negative outer membrane, ACid Fast cell wall of Mycobacterium Question 9 Bonus: You are treating a patient with inhalation anthrax with antibiotics. After 2 weeks of antibiotics, the patient seems greatly improved and you discharge the patient.Which of these statements is true? An antibiotic is any substance produced by a organism that is antagonistic to the growth of prokaryotes An antibiotic is any substance produced by a prokaryote that is antagonistic to the growth of other viruses An antibiotic is any substance produced by a prokaryote that is antagonistic to the growth of eukaryotic cells An antibiotic is any substance produced by a prokaryote that prevents growth of the same prokaryote.Safari File Edit View History Bookmarks Develop Window Help Fri Feb 4 9:35 PM catcourses.ucmerced.edu P N JC О МуМer...

One antibiotic that has been used to treat staph infections is methicillin. However, resistance to this antibiotic has become a widespread problem. The graph below shows the percentage of S. aureus strains that have become resistant to methicillin over a 20-years period in the United States. As you may have heard, methicillin-resistant S. aureus strains are called MRSA. Explain these data. Is evolution occurring? If so, propose a hypothesis to explain why S. aureus populations are evolution with regard to antibiotic resistance. Copyright © McGraw-HII Education.
