Eer refers to
a. a set of nutrient recommendations that includes rdas, ais, and uls.
b. a person's actual calorie needs, as measured by calorimetry.
c. the level of dietary intake of a nutrient that is likely to meet the needs of nearly all healthy individuals in a particular life stage and gender group.
d. estimated calorie needs for the average person of a specific height, weight, age, gender, and physical activity pattern.

The correct answer is option d. "estimated calorie needs for the average person of a specific height, weight, age, gender, and physical activity pattern".

Explanation:

The Estimated Energy Requirement (EER) is the average dietary energy intake that a person needs to maintain energy balance. EER is expressed in calories and it should be calculated in each person since it depends on the specific height, weight, age, gender, and physical activity pattern. Different equations are available to calculate the EER, however it is recommended to see a nutritionist to have the more accurate calculation as well as a diet plan to allow to be as healthy as possible.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
