Question

Mention the four characterestic of warm blooded animals??

Answer 1

Explanation:

Characteristics of warm blooded animals:

• They can keep their body temperature constant. So also known as homeothermal.
• They maintain their body temperature higher than their environment by some metabolic processes like contraction of muscles, friction produced by flow of blood etc.
• They have a higher basal metabolic rate, and also a greater capacity to increase their metabolic rate.
• They usually have well-developed insulation in order to retain body heat.
• In hot environments, they use evaporative cooling to shed excess heat (eg- by sweating).

Examples:-

Aves (crow, parrot, peacock, sparrow, kiwi etc) and Mammals (man, dog, camel, rat etc) are warm blooded animals

Answer 2

Answer:

characteristics of warm-blooded animals?

• Can maintain a constant body temperature irrespective of the ambient environmental temperature

• Endotherms have a higher basal metabolic rate than ectotherms

• Exhibits well-developed thermal insulation (such as fur, tuft, fat, feathers, hair etc.)

• Endotherms sweat to lose excess body heat (perspiration)

✯What Is An Endothermic Animal?

An endotherm, as the name suggests, is used to refer to warm-blooded animals. They are the animals who maintain a constant body temperature irrespective of the ambient temperature. Primarily, endothermic animals constitute birds and mammals of the animal kingdom. However, some fish also are endothermic.

✯Endotherms: Warm-blooded Animals

• If there is a fluctuation, i.e., if the heat generated is lesser than the heat loss, metabolic rate rises to make up for this loss. Shivering is another mechanism that humans and most other warm-blooded animals use to raise their body temperature.

• But in case the heat loss is lesser than the heat generated, panting or perspiration mechanism takes place to increase the heat loss. This is the reason why humans sweat when we feel hot. Endotherms can survive and stay active at lower environmental temperatures, unlike the ectotherms.

• However, they need food in comparatively more quantities to maintain a constant temperature. Hence, they require more fats and sugars to produce heat in order to survive in cooler temperatures. Heat generated originates from internal organs in endothermic animals. For instance, nearly two-thirds of heat is generated in the thorax region in humans, and about sixteen per cent is generated by the brain.

• With temperature, the rate of chemical reactions fluctuates, because the temperature is influenced by the rate of collisions between molecules and since the reactions may be controlled by temperature-sensitive enzymes. Reactions tend to pick up speed at higher temperatures up till a point, after which rate drops distinctly due to denaturation of enzymes. Every entity has its own set of enzymes that are effective for a particular range of temperature and metabolic reactions.

• Entities ensure the proper functioning of these metabolic reactions by maintaining the range of temperature.

✯Are all Mammals Warm-blooded Animals?

• From a scientific perspective, the thermoregulation of animals is not very clear cut. For instance, bats are mammals and all mammals are warm-blooded. However, since the surface area of these animals is quite small, they need a very high-energy expenditure just to maintain their temperature.

• Hence, these animals let their temperature drop slightly below the “normal” operating temperatures. However, they don’t let their temperatures drop as low as the cold-blooded animals, where it falls to the temperature of the ambient environment.
