Answer to Question 1

ANS: D
Lymph nodes increase rapidly and reach adult size at approximately age 6 years. They continue growing until they reach maximal development at age 10 to 12 years, which is twice their adult size. A rapid decline in size occurs until they reach adult size by the end of adolescence.

Answer to Question 2

ANS: A
Sensitive periods are limited times during the process of growth when the organism will interact with a particular environment in a specific manner. These times make the organism more susceptible to positive or negative influences. The sequential period, terminal points, and differentiation points are developmental times that do not make the organism more susceptible to environmental interaction.
