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.
This because ice is less dense than water of particular temperature range. Water reaches its maximum density at 4 degrees. Ice is important especially for aquatic life in the polar regions. Polar bears give birth and hunt on sea ice and they need it to travel from one region to another. The ice edge in coastal areas is an important feeding ground for the walrus that uses the ice as diving platforms to feed on clams on the sea floor. Ice algae grow at the porous bottom of sea ice and form the base of the unique marine food web connected to sea ice
Condensation is the process by which water vapor is changed back into liquid water. Condensation is very important to our weather and climate because it is what is responsible for cloud formation.
Without clouds, we would not get to the third phase, called precipitation, which we will talk about in a minute. Clouds form when water vapor condenses around small particles, like bits of dust or smoke in the air. Depending on the size of the drops, these particles may or may not be visible. Even on a clear, cloudless day, water vapor is always present in the atmosphere, but it does vary in amounts. We know it is present on a very humid day; it often feels like we need to swim through the air! Fog is condensation near the ground.
<span>Fog forms when moist warmer air comes in contact with cooler air near the surface. Just like when the bathroom mirror gets all foggy during a shower because of condensation, fog also forms because of this warm air contacting a cooler air mass. The fog forms drops in the air rather than on the surface of your mirror.</span>Clouds will be useless since they will not carry and drop water.
Hello there,
Qn 1: D, Fewer pests will enter the environment- because the crops are genetically modified to prevent insects from consuming them.
Qn 2: D, How the genetic code of cloned organisms differs from other organsims. -scientists must ensure that codes of genetically modified organisms are totally different from the original organisms.
Hope this helps :))
