Answer:

Warm-blooded creatures, like mammals and birds, try to keep the inside of their bodies at a constant temperature. They do this by generating their own heat when they are in a cooler environment, and by cooling themselves when they are in a hotter environment. To generate heat, warm-blooded animals convert the food that they eat into energy. They have to eat a lot of food, compared with cold-blooded animals, to maintain a constant body temperature. Only a small amount of the food that a warm-blooded animal eats is converted into body mass. The rest is used to fuel a constant body temperature.

 

These thermal infrared images of warm-blooded animals, show how birds and mammals maintain body temperatures well above the surrounding, cooler air temperature.

Cold-blooded creatures take on the temperature of their surroundings. They are hot when their environment is hot and cold when their environment is cold. In hot environments, cold-blooded animals can have blood that is much warmer than warm-blooded animals. Cold-blooded animals are much more active in warm environments and are very sluggish in cold environments. This is because their muscle activity depends on chemical reactions which run quickly when it is hot and slowly when it is cold. A cold-blooded animal can convert much more of its food into body mass compared with a warm-blooded animal.

 

The infrared images above, show how cold-blooded animals take on the temperature of their surroundings. Both the gecko and the scorpion are at the same temperature as the air surrounding them. Notice the difference between these cold-blooded creatures and the warm-blooded humans holding them.

Staying Cool and Keeping Warm

To stay cool, warm-blooded animals sweat or pant to loose heat by water evaporation. They can also cool off by moving into a shaded area or by getting wet. Only mammals can sweat. Primates, such as humans, apes and monkey, have sweat glands all over their bodies. Dogs and cats have sweat glands only on their feet. Whales are mammals who have no sweat glands, but then since they live in the water, they don't really need them. Large mammals can have difficulty cooling down if they get overheated. This is why elephants, for example, have large, thin ears which loose heat quickly. Mammals have hair, fur or blubber, and birds have feathers to help keep them warm. Many mammals have thick coats of fur which keep them warm in winter. They shed much of this fur in the summer to help them cool off and maintain their body temperature. Warm-blooded animals can also shiver to generate more heat when they get too cold. Some warm-blooded animals, especially birds, migrate from colder to warmer regions in the winter.

 

The above infrared images show some ways in which warm-blooded animals try to maintain a constant temperature. The dog in the left image pants when he is too warm. Notice the extra heat radiating from the dog's mouth as he pants. The flamingos in the right image are covered with feathers which help keep these birds warm when it is cool outside.

Cold-blooded animals often like to bask in the sun to warm up and increase their metabolism. While basking, reptiles will lie perpendicular to the direction of the sun to maximize the amount of sunlight falling on their skin. They will also expand their rib cage to increase their surface area and will darken their skin to absorb more heat. When a reptile is too hot, it will lie parallel to the sun's rays, go into a shady area, open its mouth wide, lighten its skin color or burrow into cool soil. Some cold-blooded animals, such as bees or dragonflies, shiver to stay warm when in a cold environment. Fish who live in areas where the winters are cold move to deeper waters during the colder months or migrate to warmer waters. Some fish have a special protein in their blood which acts like anti-freeze to help them survive very cold water temperatures. Snakes, lizards, toads, frogs, salamanders and most turtles will hibernate during cool winters. Some insects die when it gets too cold, however others survive by migrating to warmer areas or moving underground. Honeybees stay warm by crowding together and moving their wings to generate heat.

Explanation:

Pure calcium carbonate can be produced from marble, or it can be prepared by passing carbon dioxide into a solution of calcium hydroxide. In the later case calcium carbonate is derived from the mixture, forming a grade of product called "precipitated calcium carbonate,” or PCC.
