Microorganism Quizzes Online & Trivia

Option C - Biodegradable Biodegradable refers to any substance or object that can be decomposed by bacteria or other living organisms. The compound is anything that is composed of 2 or more elements or mixture. Environment-friendly refers to materials that have little or no harm to the ecosystem. Recycled refers to any waste material that is converted into a new substance or object.  

In order to kill microorganisms, antiseptics can be used to make this possible. The antiseptic can be effective in inhibiting the growth of the microorganism especially on the outer portion of the body but there are also some that can be consumed so that microorganisms inside the body can also be killed. Sterilization is different because it does not make use of chemicals in order to make the object or the person free from bacteria. This can actually eliminate every living thing that is in a certain surface area. Thermal disinfection does not make use of chemicals too. Rather, heat is used in order to sterilize different medical equipment and tools to make them safe to use again.

It may seem that nails, tissues, and money have nothing in common. However, they have something in common with each other. They have a general commonality that they share with millions of other things. This may be why you did not notice what they have in common. They are considered to fall under the category of fomites.

Tissues are used and contain many germs because people blow their noses on it. Then it must be moved to the trash can. Many people often handle money.

Mycobacterium tuberculosis-the correct answer is d.mycobacterium tuberculosis is an important obligate aerobe to remember for usmle step 1. (other obligate aerobes include all other mycobacteria, bordetella pertussis, and francisella tularensis.). this organism can obtain energy only from respiration and must use oxygen as the terminal electron acceptor. primary infection occurs in the upper lobes of the lung. bacteroides fragilis(choice a) is an obligate anaerobic gram-negative bacillus that constitutes the primary organism found in the colon. it is the most common cause of anaerobic infections, including abdominal abscesses and peritonitis. clostridium perfringens(choice b), along with all the other clostridium species, is an obligate anaerobic, spore-forming, gram-positive bacillus. c. perfringens is an important cause of infection following trauma and surgery and can cause gas gangrene (which can be life-threatening if not treated). c. perfringens can also cause food poisoning. e. coli(choice c) and p. aeruginosa(choice e) are both facultative organisms, meaning that they can grow both in the presence or absence of oxygen. e. coli can ferment under anaerobic conditions or respire using oxygen as the terminal electron acceptor. p. aeruginosa cannot ferment. it respires only, using nitrate as the terminal acceptor under anaerobic conditions and oxygen as the terminal electron acceptor under aerobic conditions

I've read minimum 15 seconds or 20 seconds. Therefore, 10 seconds would be too short and would lean towards 20 seconds at the other option for safety. Any discussion on this? Or does exam want 10 seconds for an answer?
