Answer to Question 1

ANS: D
Carbon dioxide is able to form different compositions when dissolved in water. First, it creates
carbonic acid, a weak acid. The acid then disassociates into bicarbonate and carbonate. Information
can be found in the section The Ocean's Acid-Base Balance Varies with Dissolved Components and
Depth.



Answer to Question 2

ANS: B
The mixing time of the ocean is due to vigorous current activity. This activity allows constituent
materials to become evenly distributed throughout the ocean. Information can be found in the section
Seawater Consists of Water and Dissolved Solids.

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.

Side effects from substance abuse include nausea, dehydration, reduced productivitiy, and dependence. Though these effects usually worsen over time, the constant need for the substance often overcomes rational thinking.
