Explanation:
The white mice are well adapted to survive in cold winter months and snowfall, where they can easily hide to avoid predation. The brown mice in are more suited to the autumn, spring and summer; the trees lose their leaves before cold seasons.
Tree litter and leaves will offer great protection for brown mice in warmer months. Camouflage is a defensive adaptation to avoid predation; to avoid detection, the rabbits mix in natural colors, shapes, and patterns. At the beginning of longer winters, brown mice will not be able to avoid wolves by playing in snow; they would stand out, while white mice would blend in, in comparison to their surroundings.

Explanation:
The alimentary canal has four main layers:
Mucosa (innermost layer which surrounds the lumen), submucosa (connective tissue with blood vessels, lymphatics, and nerves), muscular layer, serosa ( outermost layer of connective tissue).
Muscular layer is subdivided into:
• the inner- arranged in circular rings, prevents food from travelling backward
• outer layer- arranged longitudinally, shortens the tract.
The stomach has an extra layer called inner oblique muscular layer (churning function).
