Chapter 33, Problem 1MCQ

Summary Introduction

Introduction:

Thermoregulation is mechanism through which the body temperature is controlled. In this process, the heat gained from the environment, and lost to the environment is balanced by the body. This process is responsible for maintaining the homeostasis of the body.

Expert Solution & Answer

Answer to Problem 1MCQ

Correct answer:

The animal whose body temperature would drop the fastest in a cold environment is a lizard. Therefore, option d. is correct.

Explanation of Solution

Reason for the correct statement:

The internal temperature regulating mechanism is not present in the ectotherms, and the temperature of the ectotherms depends upon the temperature of their surroundings. The majority of animals, including nonavian reptiles, amphibians, and all invertebrates are ectotherm. Lizards are the reptiles, which are also ectotherm and cannot regulate their internal body temperature.

Option d. is given as "A lizard".

As, “A lizard is an ectotherm which cannot regulate its internal temperature and changes its body temperature according to the environment”, is the right answer.

Hence, option d. is correct.

Reasons for the incorrect statements:

Option a. is given as “A whale”.

A whale is a mammal, which can regulate it internal body temperature. So, it is a wrong answer.

Option b. is given as “An Arctic bird”.

An arctic bird is an endotherm, which can regulate its internal body temperature. So, it is a wrong answer.

Option c. is given as “A tropical bird”.

A tropical bird has feathers, which help in retaining the body in the birds. So, it is a wrong answer.

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

Conclusion

A lizard’s body temperature would drop the fastest in a cold environment.
