14. As food travels through the digestive system, it is exposed to a variety of pH levels. The stomach has a pH of 2 due to the presence of hydrochloride acid (HCl), and the small intestine has a pH ranging from 7 to 9. HCl converts pepsinogen into pepsin, an enzyme that digests proteins in the stomach. Which of the following most likely happens to pepsin as it enters the small intestine? A. It becomes inactive. B. It begins to replicate. C. It's shape changes to engulf large proteins. D. It's activity increases to digest more proteins.

Tuesday- What process requires more energy from the plant, water moving up the xylem or nutrients moving down through the phloem? Wednesday- How do the functions of stems differ from roots? How are they similar? Thursday- Describe what the lab shows about the structure and function of plants. Friday- Einstein said that if all the bees died, than all life would die off.
