5, The DV (Daily Value):

Group of answer choices

10, Comparing the bloodstream and the lymphatic system

Group of answer choices

both share a role in transporting nutrients to the body

Expert Solution

1) Hydrochloric corrosive (HCl) changes over pepsinogen to pepsin which separates proteins to peptides. HCl keeps up a pH in the stomach of roughly 2.0. It likewise breaks up nourishment and Kills microorganisms. Without enough HCl, pepsinogen is no changed over to pepsin which don't permit the breakdown of proteins

Thus, the right answer is 'Pepsin',unraveling/ "denaturing" proteins

2) The Recommended Dietary Allowance (RDA) is the average daily dietary intake level that is sufficient to meet the nutrient requirements of nearly all (97 to 98 percent) healthy individuals in a specific life stage and gender group. The RDA is intended primarily for use as a goal for daily intake by individuals.

Thus the right answer is RDA...

3) The process for setting the RDA depends on being able to set an Estimated Average Requirement (EAR). That is, the RDA is derived from the nutrient requirement so if an EAR cannot be set, no RDA will be set. The EAR is the daily intake value of a nutrient that is estimated to meet the nutrient requirement of half the healthy individuals in a life stage and gender group

The correct answer is EAR

4) undesirable eating routine is one of the significant hazard factors for a scope of ceaseless illnesses, including cardiovascular ailments, malignant growth, diabetes and different conditions connected to obesity

Correct option is heart dieases

5) .Percent Daily Value (DV) on the Nutrition Facts mark is a manual for the supplements in a single serving of nourishment... For example, if the label lists 17% for calcium, it means that one serving provides 17% of the calcium you need each day...the correct ans is is an average of the RDA for different age/gender populations for a specific nutrient

6)

1 gram of Carbohydrate contains 4 calories

So, 50 grams of Carbohydrate contains (4*50)= 200 calories

1 gram of protein contains 4 calories

so, 25 gram of protein contains (4*25)= 100 calories

1 gram of fat contains 9 calories

so, 10 gram of fat contains (10*9)= 90 calories

So, the total calorie measurement of the food is 390 calories.

7) Essential nutrients are nutrients that the body cannot make or produce in sufficient quantities. Essential nutrients must be obtained through the diet. so the right answer is may be made in the body, but in insufficient amounts.

8) Right answer is small intestine ...The primary function of the small intestine is the absorption of nutrients and minerals found in food

9 ) Biological determinants such as hunger, appetite, and taste is the major factor so the correct answer is

Taste – especially foods high in fat and sugar – and texture

10 ) the correct answer is a

both share a role in transporting nutrients to the body...The lymphatic system and the cardiovascular system are often called the body's two "circulatory systems."
