Explanation:

Question 57

Weight gain is influenced by diet (caloric intake) and exercise (caloric expenditure), which have a more variable and impactful effect than linear growth (which is more predictable and steady). So external factors like diet and exercise do affect weight gain more than linear growth.

While many adults may have low calcium and vitamin D in their diets, it is not true for "all" adults. Some adults may have diets rich in these nutrients (e.g., those who consume lots of dairy, fortified foods, or get enough sun for vitamin D synthesis). So the statement that they tend to be low in the diets of all adults is false.

Adolescence is typically considered to end around 18 - 21 years old (with some variations in definitions). A 21 - year - old can still be within the transitional period of late adolescence, so they can still be considered an adolescent.
