Question
Chapter 24, Problem 1TY
Summary Introduction
Introduction:
Microbiome refers to a particular assemblage of microbes and genes that occurs in a defined environment.
Expert Solution & Answer
Answer to Problem 1TY
The correct answer is option (c) a particular assemblage of microbes and genes that occurs in a defined environment.
Explanation of Solution
Explanation/justification for the correct answer:
Option (c) a particular assemblage of microbes and genes that occurs in a defined environment. Biome refers to a major type of habitat characterized by distinctive life forms and microbiome refers to major type of habitat characterized by distinctive microbial life forms. Hence; Option (c) is the correct answer.
Explanation for incorrect answer:
Option (a) an interaction between two different species of microorganisms. Symbiosis refers to an interaction between two different species.Hence; Option (a) is not the correct answer.
Option (b) an environment that is microscopic. Though Micrbiome is a microscopic environment correct explanation for microbiome is a particular assemblage of microbes and genes that occurs in a defined environment. Hence; Option (b) is not the correct answer.
Option (d) the entire makeup of a particular microorganism.Entire genetic makeup of a microorganism called as “genotype”. It refers to an organism’s complete set of genes. Hence; Option (d) is not the correct answer.
Option (e) both a and d. Option (a) an interaction between two different species of microorganisms and option (d) is the entire genetic makeup of a particular microorganism. Microbiome refers to a particular assemblage of microbes and genes that occurs in a defined environment. Hence; Option (e) is not the correct answer.
Conclusion
A microbiome is a particular assemblage of microbes and genes that occurs in a defined environment. Therefore; option (c) is the correct answer.

A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant). The researcher then exposed the mutant strain and a normal strain that expresses Esp to glucose and compared the levels of insulin in the blood near the osteoblasts (Figure 2). Which of the following claims is most consistent with the data shown in Figure 2 ? A Esp expression is necessary to prevent the overproduction of insulin.
