- All microorganisms have a similar range of living conditions. true / falseMicrobial forensics is the field of science that is investigating all of the different ways in which microorganisms can cause death. studies the different microbes that are detrimental to human survival. is investigating the ways in which microbes can rapidly adapt to avoid death. studies microbial composition of organisms after death. studies the vast array of microorganisms that populate the Earth.For most folks, their knowledge of the importance of microbes is limited to just those microbes that cause sickness. However, you know better! Which of the following describes a true critical feature of microbe biology illustrating their importance? they are used in the food and beverage production industry. some produce oxygen. microbes are very small, and make up a very small portion of the Earth's biomass. they are important food source for aquatic life they are critical for the process of decay. some can fix atmospheric nitrogen which is important for plant growth. they influence our neurobiology and are critical components of ruminant animal digestive systems.
- Which of these statements is false? Microbiology is one of the largest and most complex of the biological sciences O Microbiology is a specialized area of biology that deals with tiny life forms that are not readily observed without magnification. The major groups of microbes included in this field of study are bacteria, viruses, fungi, protozoa, algae, and helminths. Every single microbiologist works in a lab.Provide evidence in support of or refuting the following statement: Microbial life can exist in the complete absence of sunlight or organic nutrientsIf someone is contaminated with a bacterium from the environment, are they guaranteed to develop a disease? O Yes, contamination precedes disease and only one microbe is needed for disease development. Yes, a contamination implies that the patient will develop an illness. O No, contamination is just the mere presence of microbes in or on the body. O No, only non-living surfaces may be contaminated.
- Which of the following statements regarding microbial death is FALSE? Question options: cell walls are targeted by many microbial control agents the effectiveness of an antibacterial agent is a funciton of its microbial death rate the rate at which microbes are killed is termed the microbial death rate all of these statements are TRUE few antimicrobial agents function through the disruption of protein structure under a given set of conditions, the fraction of a microbial population that dies per minute is typically constant over timeTrue or false Most microbes that are part of the human microbiome are extremophiles.Describe two microbial activities essential to life and three that make our lives more comfortable.
- Watch this video and answer all of the following questions in detail: https://www.youtube.com/watch?v=PbgB2TaYhio What was missing in Dr. Llyod's Petri dish experiment for the microbes to grow? How much time is it estimated that these microbes would need to grow? What would be one biotechnological application afforded by learning more about deep subsurface microbes?Provide evidence in supporting or refuting the following statement: The cell, or cytoplasmic membrane, is a nonessential structure in bacteria because its function is replaced by the cell wall in these microbes. provide at least 400 of wordsProvide evidence in support of or refuting the following statement: Microbial life can exist in the complete absence of sunlight or organic nutrients minimum 500 of words
