Answer From Book Burton's Microbiology For The Health Sciences Quiz

Anton van Leeuwenhoek is often referred to as the father of microbiology due to his pioneering work in developing the microscope and discovering microorganisms. Louis Pasteur is known for his work in germ theory, Robert Koch is credited with the development of Koch's postulates in microbiology, and Joseph Lister is famous for his antiseptic surgical techniques.

The correct term for microbes that live on or in a person is indigenous microflora. Exogenous microflora, foreign microorganisms, and non-native microbiota are not the correct terms for the microbes that naturally reside in a person's body.

Saprophytes are organisms that obtain nutrients from decaying organic matter. Parasites live on or in a host organism, while mutualists and commensalists have symbiotic relationships with other organisms.

The correct term for the study of algae is phycology. Algaeology and algaeology are not recognized terms in the scientific community.

Parasitology is the study of parasites, which are organisms that live on or in another organism and benefits at the expense of the host. Arthropods, helminths, and certain protozoa are common types of parasites studied in the field of parasitology.

Rudolf Virchow is known for proposing the theory of biogenesis, which states that living organisms can only arise from pre-existing living organisms. The other three options, Louis Pasteur, Charles Darwin, and Gregor Mendel, made significant contributions to science but not specifically in proposing the theory of biogenesis.

Obligate intracellular pathogens can only survive and replicate within host cells. Rickettsias, chlamydias, and viruses are examples of such microbes, whereas streptococcus, staphylococcus, mycoplasma, salmonella, E. coli, enterococcus, aspergillus, candida, and cryptococcus are not classified as obligate intracellular pathogens.

Microbes are tiny organisms that exist everywhere in nature, including the air, water, and soil. They are incredibly diverse and can be found in extreme environments. The statement 'microbes are ubiquitous' is true because microbes are indeed present in abundance across various habitats.

Prions and viroids are smaller than viruses as they consist of only protein molecules (prions) or short strands of RNA (viroids). Bacteria, fungi, and parasites are larger and more complex organisms compared to viruses.

Louis Pasteur is credited with introducing the terms 'aerobes' and 'anaerobes' in the field of microbiology.

The correct answer is 3 um as it reflects the typical size of a rod-shaped bacterium (bacillus). The incorrect answers of 1 um, 5um, and 10 um are not within the average length range of most rod-shaped bacteria.

The total magnification of a compound light microscope is calculated by multiplying the magnification of the objective lens by the magnification of the ocular lens. In this case, the high-power objective lens provides a magnification of 40X (4X objective lens x 10X ocular lens), resulting in a total magnification of 400.

The resolution of the transmission electron microscope is 1,000,000 times better than the resolution of the unaided human eye, making it capable of observing structures at a much smaller scale.

The resolution of the transmission electron microscope is 1,000 times better than the resolution of the compound light microscope, due to the electron's shorter wavelength compared to visible light.

The resolution of the transmission electron microscope is estimated to be approximately 100 times better than the resolution of the scanning electron microscope. This significant difference is due to the shorter wavelength of electrons used in transmission microscopes compared to the longer wavelength used in scanning microscopes.

The limiting factor of a compound light microscope refers to the factor that ultimately determines the maximum resolution or level of detail that can be achieved. In the case of a compound light microscope, the wavelength of visible light is the limiting factor due to the wave nature of light.

While Antonie van Leeuwenhoek is known for his significant contributions to microscopy, the credit for developing the first compound microscope is given to Hans Jansen.

A compound light microscope contains multiple magnifying lenses, specifically the eyepiece and the objective lens, which work in combination to provide higher magnification than a simple microscope. The stage is a common feature in both types of microscopes.
