Hey there,
There are many ways waves can shape Earth's surface. For example, the waves can constantly brush up against a rocky ledge or cliff, and it can shape the cliff. It can change it's shape and/or form and can break away the rock or land. The waves can also bang against the rock, making it loose and the rock shapes itself by falling off or apart. This is otherwise known as erosion.
Best Of Luck,

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.
Answer:
Lipids are a type of fat.Fats are just one type of lipid, a category of molecules united by their inability to mix well with water. Lipids tend to be hydrophobic, nonpolar, and made up mostly of hydrocarbon chains
