Here's the question: "Do we know all the essential nutrients (for humans) including the amounts required by humans for healthy nutrition?" What do you think? What is the evidence? What is the difference between "essential nutrients" and "RDI amounts of essential nutrients"? If you were a research scientist how would you prove your hypothesis? We are not asking about "foods" but rather "essential nutrients" - there's a difference!. We are not talking about "therapeutic nutrition" but rather "normal nutrition" "Science doesn't know everything" is not a good answer. "New foods will be discovered" is not a good answer. Your answer should not include herbal

- Why are "fixed formula diets" for animals more beneficial than "variable formula diets"?Introduction to Experiment 2: Protein Digestion by Pepsin In this experiment, we will look at for evidence of protein digestion using albumin, a protein, and Biuret reagent. Biuret reagent is used to test for the presence of proteins, or more specifically, peptide bonds. When long polypeptide chains are present the solution will turn violet, and when shorter polypeptide chains are present the solution will turn a lighter pink color. What is/are the end product(s) of protein digestion? ____________________________________________________________ What is the purpose of the enzyme pepsin? _______________________________________________________________________ If protein digestion has occurred, will the solution be violet or pink (choose one)? _________________ Hypotheses/Predictions (See Methods section for details): What color do you expect the solution to turn when the P tubes are mixed with Biuret solution and why? P1…how can a diet that is 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates
- Recently, your secret office – called section 11 – was asked to determine if some small furry animals found in a crashed Tick-Tack looking craft in the ocean could be fed and maintained. So, you try to feed the little furry creatures, the same food they fed the recovered crash site aliens back in the 1950s: - When you fed each adorable creature, 1.0 carrot per day about half of them, got really sick; the other half seemed healthy - When you fed each adorable creature, 1.5 carrots per day, they all appeared to be healthy - When you fed each AC (adorable creature) 2.0 carrots per day they appeared to be eating too much and had gas. Knowing what you know about the DRIs - Dietary Reference Intakes: The RDA for the furry adorable creatures was how many carrot(s) per day?An Indigenous Peoples’ History of the United States (2014) Roxanne Dunbar-Ortiz 1.Indigenous agriculture was based on what crop?2.

Besides use for energy, what are some other situations in which amino acids would be converted to non-protein molecules and stripped of their nitrogen? Group of answer choices When a person has not eaten in several hours amino acids can be used to make blood sugar When a person eats a low-carb diet, amino acids can be converted to blood sugar When excess amino acids are consumed they can be converted to glycogen for storage When excess amino acids are consumed they can be converted to protein for storage When excess amino acids are consumed they can be converted to fat for storage
