Expert Solution & Answer

Summary Introduction

Introduction: The body contains a well-defined system to protect itself from infections and harmful agents. This system is known as the immunity system. The two types of immunity systems are innate and adaptive immunity. The immunity that an organism contains from the time of birth is called innate immunity. However, the immunity that the organism acquires during its lifetime is called adaptive immunity.

Answer to Problem 1TY

Correct answer: Antibodies is not an example of a barrier defense in animals. Hence, the correct answer is option e.

Explanation of Solution

Reason for correct answer:

Barrier defense is a defense mechanism of the body in which it creates a barrier around the cells. It is the most common defense mechanism used by majority of organisms. The skin is the best example of a barrier defense. These defenses are not generated as a response to the invading pathogens. They are present naturally in the body. They are part of the innate immunity system. However, antibodies are involved in the adaptive immune system. They are generated as a response to the antigens of the invading pathogens. The antibodies are not a barrier defense in animals as they do not create any barrier to protect the body from pathogens.

Option e. is given as “antibodies”.

The example which is not a barrier defense in animals is antibodies. Hence, the correct answer is option e.

Reasons for incorrect answer:

Option a. is given as, “skin”.

Skin is the best example of a barrier defense. It acts as a barrier to protect the body from the entering pathogens. It is the largest defense barrier of the body. Hence, option a. is incorrect.

Option b. is given as, “secretions from skin glands”.

The skin is an example of barrier defense. The secretions from skin glands also act as a defense barrier. They help the skin to prevent the pathogens from entering the body. They form a barrier around invading microbes and kill them. Hence, option b. is incorrect.

Option c. is given as, “exoskeleton”.

Some animals contain an external skeleton system such as insects. This type of skeleton system helps in protecting the body from pathogens. The exoskeleton is a defense barrier present in some animals. Hence, option c. is incorrect.

Option d. is given as, “mucus”.

The mucous membrane secretes a fluid known as mucus. Mucus is sticky and has antimicrobial compounds. It protects the mucous membrane from the invading microbes as the microbes stick to mucus and die. Mucus is an example of a defense barrier as it creates a sticky barrier around the pathogens. Hence, option d. is incorrect.

Hence, the options a., b., c., and d. are incorrect.

Conclusion

Therefore, the example which is not a defense barrier is antibodies. It does not create any barrier to protect the body from pathogens.

Students have asked these similar questions

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
