Accepted Answer

During adolescence, the body undergoes significant changes and growth, which increases the need for vitamins to support physical and mental development. Additionally, adolescents often have poor dietary habits and may engage in risky behaviors that increase the need for vitamins, such as drug or alcohol use. Therefore, the need for most vitamins increases during adolescence.

A) greater than
B) less than
C) the same as

Accepted Answer

Teenagers are in a stage of growth and development, which requires a significant amount of energy.

Therefore, the total amount of energy needed by teenagers is usually greater than that needed for an adult.

B) Adolescent males have a greater iron requirement for tissue synthesis than adolescent females.
C) The need for iron rises dramatically between childhood and adolescence.
D) Total iron needs are greater for adolescent males than adolescent females who have begun menstruating.

Accepted Answer

The statement that total iron needs are greater for adolescent males than for adolescent females who have begun menstruating is false. Adolescent females who menstruate have increased iron needs to compensate for the loss of iron through menstrual blood loss. This can make their iron requirements as high as or higher than those of males, especially during heavy menstrual periods.

Question 17

Scientific studies have shown that smokers consume fewer fruits and vegetables than nonsmokers.

Baked potato with low-fat sour cream is a healthier option as it is not deep-fried like French fries and provides a source of fiber and nutrients from the potato. The low-fat sour cream is also a healthier choice compared to the high-fat and calorie-laden toppings often offered with baked potatoes.
