catabolism; a break-down of macro food molecules to smaller ones. Digestion begins in the mouth‚ for a cow the teeth structure is very different from humans.

1. Honey bees have been shown to have a wide range of cognitive skills. They are sensitive to odors (including pheromones)‚ tastes‚ and colors‚ including ultraviolet. They learn such things as color discriminations through classical and operant conditioning and retain this information for several days at least; they communicate the location and nature of sources of food; they adjust their foraging to the times at which food is available; they may even form cognitive maps of their surroundings.
