Question

Constant body temperature is found in [DPMT 1985]
A) Earthworm
B) Snake
C) Frog
D) Cow

Answer 1

Constant body temperature is found in Cow.

Concept:

An organism that maintains the constant body temperature or metabolically favourable temperature is known as endotherm.

It uses the heat generated from internal systems of body and doesn't depends on the outer parameters.

Groups of mammals and birds contain these type of endotherms.

Explanation:

As we all know our body work on perticular temperature.

Increase or decrease in temperature of body causes several dysfunctioning.

Let us take the example of enzymes,

At higher temperatures enzymes start degrading and at lower temperature the didn't get proper excitation.

Hence, it is necessary to maintain the constant body temperature.

In humans hypothalamus is known as thermostat of a body , which regulates the body temperature to constant temperature.

Here, as we all know cow is a mammal so the correct answer is cow.

Answer 2

Answer:

D) Cow

Explanation:

Cows need to keep a steady core body temperature because they are warm-blooded mammals, like all other mammals. A cow's typical rectal temperature is about 38°C (101°F). Animals do not need to use any additional energy to maintain their body temperature within a range of environmental temperatures known as the "thermoneutral zone."
