The classes of chordata which are warm-blooded are birds and mammals.
Explanation:
Warm-blooded animals are those which can maintain their body temperature at a constant.
These classes of chordates balance their internal body temperature with that of the outer environment. When the outer environment is cold, they increase their internal temperature by producing more heat; and when it is hot outside they reduce their internal temperature by cooling themselves.
The food consumed by a warm-blooded animal fuels to maintain a constant body temperature and hence they require more food.
Warm blooded animals cool themselves with the help of sweat glands.
The skin and other parts like fur in birds help to keep the animals warm during winter. Birds also shed their fur in hot season to keep them light. Birds migrate to warm regions during winter.
These animals have high stamina and energy to survive environmental changes. They maintain their temperature through endothermy, homeothermy or tachymetabolism.
Whale living in water is the fish which is also warm blooded because it is a mammal.

Answer: In the restaurant business, the use of plastic can sometimes be unpreventable, as it serves many purposes and plays a vital role in our consumption of food. One of the great advantages of plastic is that it’s designed to last for a very long time: nearly all of the plastic ever created still exists in some form today. It is in use all around us — from protecting products, to the interior of our cars, to preserving food, to the medical devices used in hospitals every day. While there are numerous positive characteristics of plastic, there are also some considerable negatives. Every day, many plastic items are only used once and then are thrown away, generating one of the fastest growing problems for the environment. We call this “single-use plastic.”
There are countless amounts of plastic items in our landfills and additionally, in our lakes, rivers and oceans. Since it takes years and years for plastic to decompose, it can release toxic chemicals into our soil and water, which can affect human health and wildlife.
With this in mind, it is important not only for individuals to reduce their plastic use, but for restaurants to lead in example by reducing the amount of plastic generated in the workplace. Many large companies like Starbucks, IKEA, and Disney have already committed to eliminating single-use plastic waste in the near future, and we expect many others will follow suit. Here are five tips to help contribute to reducing plastic waste:
