The identities of microorganisms on our planet
- a. are mostly known.
- b. have nearly all been identified via microscopy.
- c. have nearly all been identified via culturing techniques.
- d. are still mostly unknown.
Introduction:
The diversity of microbes is very vast and diverse. Identification of new microbes is still studied and various researches have conducted the identification of new strains or species. Various physical and chemical tests are performed to determine the metabolic functions which are specific to species of microbes.
Answer to Problem 1Q
Correct answer:
The identities of various microbes are still unknown on the planet Earth. Therefore, option (d) is correct.
Option (d) is given as “are still mostly unknown”.
Explanation of Solution
Justify reasons for the correct statement:
All the microorganisms present on the planet are not known. There are many species present on the planet Earth which have not been discovered to date. The planet is very diverse and various species and strains of microbes are present in it.
Hence, option (d) is correct.
Justify reasons for the incorrect statements:
Option (a) is given as “are mostly known”.
No, all the species on the planet have not been identified. Hence, it is a wrong answer.
Option (b) is given as “have nearly all been identified via microscopy”.
Microscopy is the technique used for the identification of microorganisms. Hence, it is a wrong answer.
Option (c) is given as “have nearly all been identified via culturing techniques”.
Culturing is used to grow microorganisms and not for identification. Hence, it is a wrong answer.
Hence, options (a), (b), and (c) are incorrect.
Microbiologists claim that many microorganisms present on the planet have not been identified yet. There are so many species of microbes which are unidentified.

- Some potentially pathogenic bacteria and fungi, including strains of Enterococcus, Staphylococcus, Candida, and Aspergillus, can survive for one to three months on a variety of materials found in hospitals, including scrub suits, lab coats, plastic aprons, and computer keyboards. What can hospital personnel do to reduce the spread of these pathogens?arrow_forwardYou were tasked to aseptically collect different environmental samples from a quarry site and process them back in the laboratory for microbial cultivation and analysis. After all the thorough experiments, you were only able to cultivate and study 36 microorganisms. However, based on the metagenomic analysis conducted, there are about 140 other species present in the samples collected. Why is this the case? Discuss and expound on the possible reasonarrow_forwardAn infectious dose of several million cells in enteric infections seems like a lot. a. In terms of the size and abundance of microbes, could you see a cluster containing that many cells with the naked eye? b. About how long would it take an average bacterial species to reach the infectious dose of a million cells starting from a single cell? c. Why do enteric diseases require a relatively higher infectious dose than nonenteric diseases? d. Explain why antimicrobic therapy used on gram-negative bacterial infections could actually lead to illness rather than cure itarrow_forward
