Sample Questions


1. Saliva contains the enzyme amylase, which breaks down polysacharride. The amount secreted in
the mouth is clearly enough to handle a morsel of bread. However, as that morsel continues through
the digestive tract, it requires an amylase flush while entering the intestines. Which of the following
is an indirect reason for this requirement?

A. Polysacharrides might be resistant to amylase in saliva, but not to intestinal amylase
B. The temperature of the esophagus and stomach do not allow the enzyme to work efficiently
C. Carbohydrides are digested in the intestines
D. Proteins are degraded in the stomach
E. None of the above

2. During meiosis, what happens to the chromosomes?

A. They lose some genes
B. They gain new genes
C. They increase in number
D. They become fewer in number
E. They exchange genetic information

Answers: 1.D, 2.E

Test Prep Strategies


  • Study during high school! Nearly everything you need to know for the Biology subject test is covered in your biology classes in high school, so make sure you pay attention!
  • Find out what you don't know! In order to get the most out of your test prep time, take a level test and focus on the areas that you are less familiar with.
  • Become a proficient memorizer! Biology is famous for requiring its students to memorize an extremely large amount of information. That said, it is important that you recognize and think critically about the relationships between seemingly unrelated topics.
  • While you are doing practice tests, keep time! This will improve your time management skills.
