Answer to Question 1

ANS: D
An auxospore is a naked diatom cell without valves. In favorable growth conditions, the auxospore
expands to the diatom's original size. It can become dormant when conditions are unfavorable for
growth. Information can be found in the section Most Phytoplankton are Photosynthetic Autotrophs



Answer to Question 2

ANS: D
These accessory pigments allow more light frequencies to be absorbed. The yellow and brown
pigments in diatoms give them the same coloration. Information can be found in the section Most
Phytoplankton are Photosynthetic Autotrophs.

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.

The cure for trichomoniasis is easy as long as the patient does not drink alcoholic beverages for 24 hours. Just a single dose of medication is needed to rid the body of the disease.
