You believe that the most likely explanation for this rule is which of the following?

Accepted Answer

The most likely reason for the rule is to minimize peanut exposure for campers with peanut allergies. Peanut allergies can be severe and even life-threatening, and it is important to take precautions to ensure the safety of all campers.

Question 13

Which of the following is a characteristic myth about hyperactivity in children?

Accepted Answer

Myth about hyperactivity in children is that it is caused by an increased intake of sugar. While sugar may contribute to a child's energy level, it is not a direct cause of hyperactivity.

Question 14

A child with a true allergy to milk is actually allergic to which of the following compounds that might be found in milk?

Accepted Answer

A true allergy to milk is an immune response to one or more proteins found in milk. Casein is a protein found in milk and is a common allergen for individuals with milk allergies. Lactose is a sugar found in milk and is not typically the cause of a milk allergy. Lactalbumin and lactoglobulin are also proteins found in milk and can potentially cause allergic reactions, but casein is the most common culprit.
