Document Content and Description Below

Directions: Today, you will take Session 2 of the Biology Science Practice Test. Read each stimulus and question. Then, follow the directions to answer each question. Mark your answers by circling ... the correct choice. If you need to change an answer, be sure to erase your first answer completely. You may look back at the stimuli when needed. Some of the questions will ask you to write a response. Write your response in the space provided in your test booklet. Only responses written within the provided space will be scored. If you do not know the answer to a question, you may go on to the next question. If you finish early, you may review your answers and any questions you did not answer in this session ONLY. Do not go past the stop sign. Science 30 Session 2 Use the information about banded snails and your knowledge of science to answer the questions. Banded Snails Banded snails, found in Central Europe, are small- to medium-sized snails that are members of the Helicidae family. Their shells are found in a range of colors and patterns, from yellow to dark brown and from no bands (or stripes) to five bands. Image 1 shows an example of a banded snail with five bands. Banded snails are prey to several bird species, including the song thrush. The color and pattern of the bands are based on genetics and heredity, and follow the Mendelian rules of inheritance. In addition, snails with lighter-colored shells have a lower body temperature than those with darker-colored shells. In some areas, snails with many different colors and band patterns are found. In other areas, certain shell colors or patterns are more commo [Show More]
