Concept of Product Life Cycle. First referenced in the 1920s, the product life cycle applies biological knowledge to products. In nature, a seed is planted, begins to sprout, becomes an adult then eventually withers away and dies. The product life cycle focuses on introduction (seed), growth (sprout), maturity (tree) and decline (death) phases. Each phase has its own marketing mix strategy and implications regarding product, price, distribution and promotion.
The skeletal system is comprised of bones and joints and provides the basic supporting structure of the body. It consists of the joined framework of bones called the skeleton. The human skeleton is made up of 206 bones. Click here for a drawing of a the major bone structures of the body.
The skeletal system protects major organs throughout the body. Bones are connected by cartilage, joints and ligaments. The skeletal system allows the body to move around and gives it shape. Bones contain marrow inside where red and white blood cells are made and carried through the whole body by the circulatory system.
