Answer 1

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Summary Introduction

Introduction:

The humans are connected with a vast array of microbes known as resident biota. A holobiont includes the human body along with resident biota. These microbes of resident biota also prevent the overgrowth of harmful microorganisms.

Expert Solution & Answer

Answer to Problem 1MCQ

Correct answer:

The best descriptive term for the resident biota is commensals. Therefore, option (a) is correct.

Option (a) is given as “commensals”.

Explanation of Solution

Justify reasons for the correct statement:

Some organisms show evolution along with its human hosts and produce a complex relationship in which the effects of normal biota are not deleterious to the host. Normal biota is generally either in a commensal or mutualistic association with their hosts because microbes exist in different kinds of relationships with their hosts.

Hence, option (a) is correct.

Justify reasons for the incorrect statements:

Option (b) is given as “parasites”.

The parasites are the organisms which can live on host body, but they do not live in commensals like microorganisms. Hence, it is a wrong answer.

Option (c) is given as “pathogens”.

Not all pathogens live in commensals. Only some microorganisms live in commensals. Hence, it is a wrong answer.

Option (d) is given as “mutualists”.

Mutualists are the organisms which live in a relationship such that both the organisms are benefitted. Hence, it is a wrong answer.

Hence, options (b),(c), and(d) are incorrect.

Conclusion

The commensals are the microorganisms which live in a group. The resident biotas are also commensals.
