Answer: The organism that has the adaptations described that enable it to survive in the tundra is the POLAR BEAR.
Explanation:
ADAPTATION is defined as the process by which an organism becomes fitted to its environment thereby enabling the organism to live successfully and reproduce.
In any population, an organism is able to survive if it has features that help them to fit and compete successfully in that environment.
From the question, a typical example was given concerning the POLAR BEAR (Ursus maritimus) and it's best fitted environment which is the tundra.
The tundra is a type of biome that is treeless marshy vegetation which is composed mainly of dwarf shrubs. It's has a cold climate (Arctic region) with long icy winters and very short summer with an average temperature of 10°C.
Ursus maritimus has a variety of adaptations which enable it to survive in the tundra. These adaptations include:
--> The presence of a thick coat of insulated WHITE FUR: this helps it to survive the cold environment by acting as an effective insulator. The fur is also found at the base of its large paws with small bumps, which protects it against cold surfaces and provides its with a better grip of ice as it walks across it. It also gives it a concealing coloration making it unnoticed while it stalks its prey in the snow. These are the features that enables it survive the terrestrial environment if tundra.
--> it also has some aquatic adaptations which enables it to hunt it's favourite food which is seals. The presence of large front paws which are slightly webbed allows them swim for a long distance in search of food.
Oxygen from the respiratory system is delivered by the circulatory system.
<h3>What is the relationship between respiratory and circulatory system?</h3>
The respiratory system is responsible for delivering oxygen to the circulatory system that is made up of blood vessels which carry blood to the heart and then all cells of our body. Arteries carry blood that is loaded with oxygen from the heart to all cells whereas veins carry deoxygenated blood back to the heart and then to the lungs for disposing carbondioxide. The circulatory system carries oxygen and nutrients to the cells, and removes waste products such as carbon dioxide.
So we can conclude that Oxygen from the respiratory system is delivered by the circulatory system.
