Aves refers to a class of vertebrates that consists of birds. The characteristic features of birds are the presence of feathers over the body and toothless jaws. They are referred to as oviparous animals. The members of this group have a four-chambered heart, which shows the property of a complete double circulation.

Summary Introduction

Introduction: Aves refers to a class of vertebrates that consists of birds. The characteristic features of birds are the presence of feathers over the body and toothless jaws. They are referred to as oviparous animals. The members of this group have a four-chambered heart, which shows the property of a complete double circulation.

Expert Solution & Answer

Answer to Problem 1TY

Correct answer: Birds maintain a stable internal body temperature on a cold day by the property of “homeostasis”. Hence, the correct answer is option d.

Explanation of Solution

Reason for correct answer:

A process of managing internal conditions of body irrespective to the outer environment is known as “homeostasis”. The ability to maintain the internal environment of the body is a sign of evolutionary progress and it is reached by the organisms like birds and mammals. Stable temperature of the body and chemical composition allows the organism to function properly without the influence of the variable environmental conditions.

Option d. is given as “homeostasis”.

In a cold environment, the temperature of the bird’s body is maintained by “homeostasis”. Hence, the correct answer is option d.

Reason for incorrect answer:

Option a. is given as, “adaptation”.

The term adaptation refers to the development of features in an organism to sustain its survivability in that environment. Adaptation is not related to the maintenance of internal body environment. Hence, option a. is incorrect.

Option b. is given as, “evolution”.

The variations adopted by the organism leads to the process of evolution. It does not support the maintenance of body temperature. Hence, option b. is incorrect.

Option c. is given as, “metabolism”.

For the functioning of the an organism’s body processes, various chemical reactions take place inside its body. Such chemical reactions are collectively called as metabolism. It varies according to the need of the organism. However, the need for maintaining the internal temperature is a constant process. Hence, option c. is incorrect.

Option e. is given as “development”.

The process of cell cycle leads to the formation of cells, which lead to the growth and development of an individual. There is no relation between the development and maintenance of internal body temperature. Hence, option e. is incorrect.

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

Conclusion

On a cold day, birds maintain a stable temperature in their body by “homeostasis”.
