What are warm-blooded and cold-blooded?

Answer 1

Warm-blooded means that at rest, the animal keeps its body warm and above the temperature of its surroundings.

Cold-blooded means that at rest, the animals body temperature is the same as that of its surroundings.

Cold-blooded animals have to warm themselves up (usually by sunning them selves or by vibrating their muscles) before they become active while warmblooded animals are already warm and ready for action. Also warmblooded animals can operate at temperatures where cold-blooded animals can not (eg polar bears).

--------------------------------------------------------------

Warm Blooded try to keep the inside of their bodies at a constant temperature. Examples:

Birds and Mammals

Cold Blooded take on the temperature of their surroundings. Examples:

Fish and Reptiles
Warm blooded: Requires little or no external heating. Mammals.

Cold blooded: Requires external heating. Most others than mammals.
Cold blooded Mollusk are type of invertebrate animals. They are poikilothermic animals i.e. cold blooded. mollusks are cold-blooded because they change the temperature of their bodies in the...

Snakes, lizards, tortoises and frogs and toads and newts, are all cold blooded. Basically most amphibians, all fish, and most reptiles are cold blooded. All mammals are warm blooded. That includes: Whales, Dolphins, elephants, dogs, and humans.
Bears are mammals, and all mammals are warm blooded. Sharkes are not mammals, they are fish and therefore, they are cold blooded.

Answer 2

The term cold blooded refers to the way in which the bodily temperature changes with the environment. There are three main areas of thermoregulation under the umbrella term cold bloodedness. * Ectothermy - this refers to creatures that control their temperatures by external means, such as the sun, flowing air or water. * Poikilothermy - this refers to the creatures who's body temperature rises and falls with the surrounding environment. These creatures would be cold in cold areas and hot in hot ones, changing as they move between them. * Bradymetabolism - this refers to creatures who have a high active metabolism and a low resting metabolism. These creatures can undergo dramatic changes in their metabolic rate, depending on food availability and temperature. This allows creatures, such as those who live in the desert, able to shut down their body's and approach a near death sate, to survive harsh desert winters, until favourable conditions return. Only a few creatures fall into all three categories, or use more than one method to control their body temperature. Most creatures rely on one type of thermoregulation to survive, such as snake and lizards lying on rocks, or insect vibrating their muscles in one place to keep warm.

It was originally thought that cold blooded creatures were incapable of controlling their bodily temperatures. It is now known that this is not the case and the term is therefore outdated in scientific content today. The term warm blooded refers to the way in which creatures keep their body temperature at a constant level.

There are again three main areas of thermoregulation under warm bloodedness. * Endothermy - this refers to creatures that control their temperatures through internal means, such as shivering, panting, and burning fat. These actions raise the metabolic rate and produces warmth. * Homeothermy - this refers to creatures who maintain a steady internal temperature regardless of external environment. These creatures tend to have a slightly higher temperature than their surroundings. * Tachymetabolism - this refers to creatures who maintain a high metabolism, even when resting. This essentially means that these creatures are 'on' all the time. Even though their rest metabolism is slightly lower, this is not significantly noticeable.

Unlike cold blooded animals, warm blooded animals tend to fit into all three categories, some only into two. This means that these warm blooded creatures uses many methods to regulate a steady body temperature. Within the past thirty years scientists have found that some animals uses thermoregulation characteristics from both warm and cold blooded categories.

Bats and some small birds have been found to be both Poikilothermic and Bradymetabolic. For these and other creatures a new category was made, heterothermy (hetero meaning two and thermo meaning temperature).

Although the terms cold blooded and warm blooded are said to be outdated in terms of scientific accuracy, they are still widely used and understood as the regulation of temperature in organisms.

Answer 3

All mammals including all humans are warm-blooded. This means that our body temperature is regulated at least to some extent by our body and not totally by the outside temp. Cold blooded animals can only get heat from the sun or a warm surface.

Warm blooded
No, humans are warmblooded.

Answer 4

Warm blooded animals (homeotherms) maintain a consistent body temperature. Cold blooded animals (poikilotherms) will have body temperatures that vary with the temperature of their environment.

Mammals (including humans) and birds are warm-blooded animals. Reptiles and fish are cold-blooded animals.

Answer 5

Warm blooded creatures or animals generates their own heat through their metabolism and cold blooded creatures depend on the natural environment they live in to bring their bodily temperature to normal

temperature

Answer 6

Warm-blooded animals (birds and mammals) are able to maintain a steady body temperature regardless of environmental conditions. Cold-blooded animals (reptiles, amphibians, fish, insects, crustaceans, worms, etc.) are not.

Answer 7

Humans are warm blodded. All mammals and birds are warm blooded. only reptiles, insects, arachnids, amphibians and fish are cold-blooded.

Answer 8

Frogs are cold blooded. Their body temperature fluctuates with the environment.

Answer 9

People are mamals and therefore warmblooded

Answer 10

Frog, like all amphibians, are cold blooded animals.
