Question

Name some countries in the world that are extremely cold. What kind of animals

are found there? List a few adaptations that help them to live well there.​

Answer 1

Answer:

This is the answer

Step-by-step explanation:

Air temperatures averaging below freezing over the year (usually well below freezing) with a range in many places around -40°C to +10°C (-40°F to +50°F) and highs (very briefly and rarely) up to +22°C (+72°F) amongst rocks and moss banks.

Much of Antarctica is a cold largely featureless icy desert where above freezing temperatures are hardly reached if ever at all. The temperature of the Antarctic Ocean that surrounds the continent varies from -2°C to +2°C (+28.4°F to +35.6°F) over the year. Seawater freezes at -2°C (+28.4°F) so it can't get any colder and still be water.

Arctic and Antarctic birds and mammals such as penguins, whales, bears, foxes and seals - are warm blooded animals and they maintain similar internal body temperatures to warm blooded animals in any other climate zone - that is 35-42°C (95-107°F) depending on the species. They have to keep high body temperatures to remain active. These animals are known as endotherms (endo-inside + therm-heat) as they generate their heat internally. The polar regions' cold and wind mean that this heat can very quickly be lost leading to hypothermia (hypo-under).

Many (non polar) animals are ectotherms (ecto-outside) , which means that they generate so little heat internally they are dependent on the external environment to warm them up to a level where their body and enzymes function sufficiently well enough for an active and functional life. Typically they raise their temperature by basking in the sun until they are warm enough to become active. Reptiles and amphibians do this while invertebrates are usually small enough to be able to warm up quickly to the ambient temperature from the air alone without basking in direct sunlight.
