<span>1. Density is the mass of a substance divided by its volume. D= m/v
2.
To measure the volume of an irregular object you can fill a container with water and submerge the item. You would then measure the volume of water that was displaced by the obect.
3. D = m/v so m = 10.00 grams and v = 15.625 cm3
D= 10.00 grams/15.625 cm3 = 0.64 g/cm3</span>
Answer:
d. "To prevent nutrient overdoses" is not a function of the Recommended Dietary Allowance (RDA)
Explanation:
The Recommended Dietary Allowance (RDA) is part of the system of nutrition recommendations which is the Dietary Reference Intake. The RDA considers the daily dietary intake level of a nutrient considered sufficient, so its function is to meet nutritional needs, to reduce risk of disease and to prevent nutrient deficiencies. However, to prevent nutrient overdoses RDA is not the right one to use. In that case Tolerable upper intake levels (UL) is the correct is the correct reference value to avoid excessive intake of nutrients. For example, vitamin A can be harmful in excesive amounts.
