Nutrition has been one of the major problems that our country is facing most specially in this time of pandemic. As one of the trusted chemists of the Local Government Unit you were tasked to make an ideal meal plan that will serve as a “meal guide’ for families in preparing their daily meals. Your food pyramid must show the BIOMOLECULES of life for each level (GO, GROW, GLOW and FLOW foods). You must also show sample computations of carbohydrates that will take place once the specific food in the food group is digested, this is to show your audience an evidence on how important your food pyramid is. You must present your work using a multimedia presentation.    In line with this task, the following must be prepared:    list of biomolecules in your meal plan; (TEST 1)  computation of chemical reaction that will take place once digestion happened; (TEST 2)  narrative/description that will explain and convince your reader on the importance of your food pyramid. (PRESENTATION –…

Dixie Bee wanted to make JELL-O shots for her next party, but felt guilty about encouraging her guests to consume alcohol. She tried to compensate for the toxicity of the alcohol by adding pieces of healthy fresh pineapple to the shots, but when she did, the JELL-O never solidified. What happened? Hint: JELL-O is mainly sugar and a gelatinous mixture of proteins.
