Answer:
-Due to acidic pH of stomach.
Explanation:
Enzymes are generally made up of protein molecules and work at an optimum pH and temperature. This is because at change in pH and temperature leads to denaturation of proteins that cause change in active site of enzyme.
For trypsin, optimum pH is slightly basic as pH (7.5). So, trypsin would become non-functional at acidic pH due to denaturation and loss of active site.
Trypsin is a pancreatic enzyme that works at small intestine as pH of small intestine is slightly basic.Thus, if the trypsin was secreted in stomach instead of pancreas, it would be non-functional as stomach has acidic pH due to stomach acid.
Answer:
Proteins are like carbohydrates and fats (lipids) because they contain carbon, hydrogen and oxygen. On the other hand, proteins also contain _nitrogen__________ while carbohydrates and fats do not.
Explanation:
Proteins are formed by units: amino acids. These are organic molecules that contain carboxyl (COOH) and amino (NH2) groups. These groups bind to the carbon called alpha (α), which also binds to a side chain (R chain) and a hydrogen atom (H). There are 20 types of amino acids.

12. Ella da el papel a ti. Ella me lo da.
13. Ella compra la manzana para Javier. Ella se la compra.
14. Nosotros vendemos el pan a las personas. Nosotros se lo vendemos.
The answer is D. Run only full loads in the washing machine and dishwasher.
B doesn't seem like a good idea, C uses more water, and A would save water but not as much as the washing machine and dishwater use.
I guess the stomach is held in place by a variety of Muscle cells, Epithelial cells, and connecting tissues; so the answer is: all of the above.
