What two adaptations that enable mammals to survive cold winters?
One adaptation that mammals have acquired to survive the harsh winter season is fur. Some mammals tend to grow a longer and thicker coat during the winter to keep them warm. Another adaptation that mammals have is the ability to eat a variety of foods. A mammalâ??s normal diet may not be available during the winter, so the ability to eat a variety can help them greatly.Hibernation and Migration.
Do amphibians feed their young with milk?

Does the hair bulb produce hair?
Only the cells of the hair bulb are alive to understand this more here is how the hair bulb if formed. Hair follicles forms a cluster of cells in the upper layer of the skin. These cluster of cells are called the primitive hair germ, which needs nourishment to grow into a developed hair follicle. To get nourishment it works all the way down into the lower layer of the skin. As it does, the cell cluster pulls the upper layer down with it creating a follicle called the root Sheath, out of which the hair will grow. The shape of this follicle then determines the shape of the hair shaft as it grows from the follicle.
What are derived characters?
Among a given group of organisms, the shared derived characters are generally the less common characters. The evolutionary interpretation is that these characters of organisms are more recently evolved. They are contrasted with primitive characters. Shared derived characters should have the same structure and function.Derived characters may be present in members of one group of the line, but not in the common ancestor. For example, in comparing fish and mammals, fish have scales and mammals have hair. So having hair is a derived character for mammals, as only the mammals have ancestors with hair.
