Answer to Problem 1TY
Correct answer: In a defined environment, many specific species of microbes are assembled. Such specific assemblage of microbes in an environment is referred to as a microbiome. Hence, the correct answer is option c.
Explanation of Solution
Reason for correct answer:
A microbiome refers to many species of microbes with their genes assembled in an environment. For example, in the human body, there are so many species of microbes playing important roles in the human health. The microbiota inside the human body is known as the human microbiome. Similar to the human microbiome, plants and animal microbiomes are also beneficial to them.
Option c. is given as “a particular assemblage of microbes (including their genes) that occurs in a defined environment”.
A microbiome is formed when many microorganisms are assembled in an environment. Within an organism, they may provide health benefits. Hence, the correct answer is option c.
Reasons for incorrect answers:
Option a. is given as, “an interaction between two different species of microorganisms”.
A microbiome does not refer to the interaction between the two species of a microorganism. It is formed when many microorganisms are assembled in an environment. Hence, option a. is incorrect.
Option b. is given as, “an environment that is microscopic”.
Microbiomes can be microscopic, but not every microscopic environment is a microbiome. Hence, option b. is incorrect.
Option d. is given as, “the entire genetic makeup of a particular microorganism”.
The entire genetic makeup of a particular microorganism can be considered as the genome. Microbiomes include several microorganisms in a defined environment along with their genetic material. Hence, option d. is incorrect.
Option e. is given as, “both a and d”.
A microbiome does not refer to the interaction between the two species of a microorganism. Microbiomes include several microorganisms in a defined environment along with their genetic material. Hence, option e. is incorrect.
Hence, the options a., b., d., and e. are incorrect.
Thus, a microbiome is a particular assemblage of microbes (including their genes) in a defined environment.

- Which of the following is NOT true about Koch's postulates? First developed by Robert Koch, the pioneering German microbiologist In the first step, the microbe that causes a naturally occurring disease is cultured from a "wild" (non-laboratory) animal which has that disease None of the other four answers (All are true about Koch's Postulates) They represent a process for showing a causal association between a specific microbe and a disease If the same microbe from a diseased "wild" (non-laboratory) host causes the same disease in a lab animal and it can be cultured from that lab animal, this proves that the microbe is the cause of the naturally occurring diseasearrow_forwardAn infectious dose of several million cells in enteric infections seems like a lot. a.

Some general changes within these three factors that may cause an infectious disease to emerge include: A. changes in populations or behavior of reservoir hosts or intermediate hosts B. microbial genetic mutation and viral genetic recombination or assortment C. environmental factors such as an increase in precipitation D. all of the above E. none of the abovearrow_forwardThe epidemiological or disease triangle is a model of disease causation that proposes three factors contribute to an outbreak - an agent that causes the disease, a susceptible host, and an environment that brings the host and agent together.
