Final answer:
The stomach has an acidic pH of 1.5 to 2.0, making the statement True. The highly acidic environment in the stomach is necessary for the chemical breakdown and digestion of food. This low pH is maintained by the secretion of gastric juices, including hydrochloric acid (HCl).
Step-by-step explanation:
The question is whether the acidic contents of the stomach have a pH of 1.5-2.0. The answer to this question is a) True. The stomach is a saclike organ that secretes gastric digestive juices which are highly acidic. This highly acidic environment, with a pH between 1.5 and 2.5, is required for the chemical breakdown of food and the extraction of nutrients. Additionally, a pH of 7 is considered neutral, and the environment in the stomach, with a pH of 1 to 2, is well below neutral and thus highly acidic.
