1) Microbes live in us, on us and nearly everywhere around us. Which of the fuilowing actlivities are microbes involved in? a) Decomposing dead organisms b) Aiding the digestive processes of grazing animals c) Capturing energy from the sur 1) Aii of the abovo 2) Which of the following is a reason microorganisms are useful in many different research laboratores (such as ecology, biochemistry, evolution and genetics)? a) They are easy to see and count b) They have fairly complex structures and are expensive They reproduce fast and grow in large numbers d) They live everywhere so contaminants from the environment are not a problem 3) A parasitologist studies parasites. What does a mycologist study a) protozoa c) the development of chemical substances to treat diseases b) how viruses cause disease and are d in cance fungi 4) While a doctor may diagnose and treat a patient who presents with a disease, an epidemiolgist a) helps in the development and use of vaccines B) investigates what organism is responsible for a particular patients disease c) figures out how to use microorganisms to clean up the environment d) studies the frequency and distribution of the disease in the community 5) What discovery was crucial to the founding of the field of microbiology? a) Isolation of lepers limiting the spread of infectious disease b) Agglutination of bacteria in immune serum GThe chemical composition of DNA, the genetic material d) Microscopes which allowed for the direct observation of microbes 6) All of the following statements agree with the germ theory of disease, except a) microorganisms can invade other organisms and cause disease b) maggots only grow on meat that is left in an open flask because microbes are transmitted by flies and do not spontaneously generate disease causing organisms will spontaneously arise from decaying mel disese is not caused by ba air or spirits a) 7) Koch's postulates were specific to anthrax and tuberculosis but don't apply to other diseases b) designed to establish a causal relationship between a causative microbe and a disease c) strict in that microorganisms isolated from experimentally inoculated hosts had to be different from the microorganism that was introduced into the host d) interpreted as many organisms could cause the same diseaseExplanation / Answer
1. Microbes play important and varied role. Hence, option d is correct.
2. Microorganisms have high rate of reproducing. Hence, option c is correct.
3. Mycologist study fungi. Mycologist word originated from mycelium present in fungi. Hence, option d is correct
4. An epidemiologist, study the cause of diseases and other factors. Hence, option b is correct.
5. Discovery crucial in microbiology is the microbes invention. Hence, option d is correct.
6. Germ theory did not said that disease is not caused by bad air. Hence, option d is correct.
7. Koch postulate designed to establish relation between causative microbes and disease. Hence, option b is correct .
