Can coffee cause a loss of appetite?
Yes and no. It's a much-loved and widely believed story that coffee is an appetite suppressant, and some people believe it helps them to lose weight. The truth is more nuanced: yes, drinking a cup of coffee can temporarily cause a loss of appetite by filling up your stomach, but the word to remember is "temporarily"-- it doesn't last very long, and drinking too much coffee can make a person anxious and jittery, due to the caffeine that coffee contains. But if you are asking whether there is a medical condition where coffee itself causes loss of appetite (not temporarily, and not intended to help a person lose weight), I have not heard of such a condition. I am sure there may be some people who have an allergic reaction to caffeine, but usually a loss of appetite is caused by other factors, and if you are not interested in eating, or cannot eat, I doubt coffee is to blame. You may want to see your doctor and have a physical exam to find out the actual cause and get the proper treatment for it.

Why is lactase not found in stomach or large intestine?
this is because Lactase activity increase at a pH of 7 and 8 but at a pH of 7, the activity is maximum. At a pH above 7, the activity is decreasing. At a pH of 1 and 2, Lactase is inactive. Therefore, Lactase work best at a pH between 7 and 8.

Is it possible to digest all your food at the same time?
It depend on the amount of food. If you simply swallow, lets say, a small strawberry, without chewing, and call that all your food, then yes, the entire strawberry would be digested at the same rate. However, if you were eating, lets say, a peice of chicken, and you were taking the time to chew and swallow each bite, then each of these swallows would be slightly off. For example, when you are chewing one peice, another might be in your esophagous, or in your stomach.

Does the stomach have thicker walls than the small intestine in a frog?
The stomach has a slightly thicker wall than the small intestine as the stomach secretes acids that are used to break down food, while the small intestine's job is just to transport the food through the digestive system
How deep is the appendix located?
The appendix is hooked on the the very end of the small intestine, just before the large intestine starts. If you are thinking appendicitis, you feel pain in the low right side of your abdomen. If you can press on your tummy there and it does not hurt too bad, but hurts when you release your 'press hold' you may have appendicitis. If you are worried, see your DR.
What is broken down by stomach churning and enzyme amylase?
The stomach breaks down mainly proteins into smaller polypeptides. However, amylase will not break anything down in the stomach because it is denatured by the acid. Salivary amylase will break down amylose, a type of starch, but only in the few seconds of mastication. Once the bolus reaches the stomach, the salivary amylase is no longer active. Carbohydrates will be broken down again in the small intestine, where pancreatic amylase will make a return after the chyme is neutralized into a basic solution.
