Answer to Question 1

ANS: B
Usually, the pubertal growth spurt begins earlier in girls. It typically occurs between the ages of 10 and 14 years for girls and 11 and 16 years for boys. The average earliest age at onset is 1 year earlier for girls. There does not appear to be a relation to growth during infancy.

Answer to Question 2

ANS: A
The first pattern of development is the head-to-tail, or cephalocaudal, direction. The head end of the organism develops first and is large and complex, whereas the lower end is smaller and simpler, and development takes place at a later time. Proximodistal, or near-to-far, is the second pattern of development. Limb buds develop before fingers and toes. Postnatally the child has control of the shoulder before achieving mastery of the hands. Mass to specific is not a specific pattern of development. In all dimensions of growth, a definite, sequential pattern is followed.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
