Based on Mead's model of development, the sequence that correctly orders the stages of developing self is this: IMITATION, PLAY, GAME, GENERALIZED OTHER. The answer for this would be the first option. Hope this answers your question. Have a great day ahead!
Answer:
C
Explanation:
Before food gets to the stomach, it is first masticated in the mouth then after swallowing, pass through the esophagus before entering the stomach. The stomach then physical churns foods that help in digestion and also produces digestive enzymes like pepsin. Stomach has folds called ruggae that increase surface area for which food is broken down by enzymes. In addition the stomach lining producs HCl that creates an acidic environment to kill bacteria. Food stays in the stomach for about 4 hours before moving on to the ileum.
