Answer to Question 1

A
The immune system responds to foreign substances, or antigens, by producing antibodies and storing information. Intact skin, mucous membranes, and processes such as coughing, sneezing, and tearing help maintain internal homeostasis. Children up to the age of 6 or 7 years have limited antibodies against common bacteria. The immunoglobins reach adult levels at different ages. Immunization is the basis from which the immune system activates protection against some communicable diseases. Antibodies are produced by the immune system against invading agents, or antigens.

Answer to Question 2

A, D, E
Children are more commonly infected with parasites than adults, primarily as a result of frequent hand-to-mouth activity and the likelihood of fecal contamination. Good handwashing can prevent the transmission. Shoes should be worn when outside to prevent transmission and fruits and vegetables should be washed before eating. The child should not swim in a pool that allows diapered children. The bathroom facilities should be cleaned with bleach to decrease the chance of transmission.
