Ail example of a nonspecific chemical barrier to infection is/are

a. unbroken skin.
b. lysozyme in saliva.
c. cilia in respiratory tract.
d. all of these.

Expert Solution & Answer

Summary Introduction

Introduction:

The body producesvarious chemical barriers which protect the body from bacteria and other harmful microbes and pathogens. For example, tears contain lysozyme which helps in the degradation of the bacterial cell wall.

Answer to Problem 1MCQ

Correct answer:

An example of a non-specific chemical barrier to infections is lysozyme in saliva. Therefore, option (b) is correct.

Option (b) is given as “lysozyme in saliva”.

Explanation of Solution

Justify reasons for the correct statement:

The non-specific chemical barrier of the body includes secretion of lubricating glands. This barrier protects the body from infections. Lysozyme is present in the saliva, which is responsible for cell wall degradation in bacteria by breaking down the peptidoglycan layer.

Hence, option (b) is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “unbroken skin”.

Unbroken skin is not an example of a non-specific chemical barrier. Hence, it is a wrong answer.

Option (c) is given as “cilia in respiratory tract”.

Cilia in the respiratory tract are not an example of a non-specific chemical barrier. Hence, it is a wrong answer.

Option (d) is given as “all of these”.

Lysozyme in saliva is the non-specific chemical barrier to infection which is produced by the body. Hence, it is a wrong answer.

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

Conclusion

Lysozyme that presentsin the saliva is an example of a non-specific chemical barrier to infection which is produced by the body.

Three of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results: Trait Number of individuals Wild type 169 Black 19 Black, hooked 301 Dumpy, hooked 21 Hooked, dumpy, black 172 Dumpy, black 6 Dumpy 305 Hooked 8 Determine the order of the genes and the mapping distance between genes.
