Compare the interaction of hair cells and gelatinous layers (otolith or ampullary cupula) for linear versus rotational motion.

Permafrost is a layer of semi-permanent topsoil found in northern areas such as Canada and Alaska. That type of area would fall into the category of tundra. Mosses and lichens would be able to grow there as well, provided the area would moist enough. Wild flowers are hardy enough to grow there as well. In the ice cap climate, the plants would not be able to grow well, and in the subtropical and temperate climates would be too warm for permafrost to appear. The answer is A. Tundra Climate.
