Answer to Question 1
Glucose can be attached together (several hundreds of glucoses) in long chains, generally called polymers. The type of bond connecting the two glucose units dictates whether it is a simple, carbohydrate energy storage form (starch) or a complex, tough, linear, cell-wall-constituent structure form, cellulose.
Answer to Question 2
Weaning is the mother ceasing to make milk or allowing the young access to suckling. Weaning also means the period of making the transition from a highly nutritious, wet and digestible diet to one of widely varying nutrient content of poorer nutritional quality and less moisture. Weaning should be managed by gradually introducing solid foods while the animal is still suckling, over a period of a few days so that it has a chance to develop the proper enzymes.
