SHORT ANSWER: Write out the task and a provide a complete answer.
1. List and describe at least 7 methods in science. 8 pts
2. List and give an example of 7 statements from your notes or book that describe Life (Life
___ ; Example). 8 pts
3. Multicellular organisms have a hierarchical structural organization, in which any one
system is made up of numerous parts and is itself a component of the next level. List eight
steps of biological organization from the Hierarchy of Life for a single organism. 5 pts
4. List and define three properties of water that make life possible on Earth. For each
property provide an example involving a living organism. 10 pts
5. List, provide a function, and give an example of the 4 main types of macromolecules. 9 pts
6. All cells contain genetic information in the form of DNA molecules. Differentiate between
DNA, Chromosome, Chromatin, Genes, Alleles, and Nucleotides. 7 pts
7. Describe the connection between DNA, RNA, Proteins, and Traits. Include in your
description the parts of the cell mostly associated with each part. 7 pts
8. Feedback mechanisms maintain a living system’s internal conditions within certain limits
and mediate behaviors, allowing it to remain alive and functional even as external
conditions change within some range. Using a specific example, describe how a feedback
mechanism can encourage (through positive feedback) or discourage (negative feedback)
what is going on inside the living system. 3 pts.
9. Systems of specialized cells within organisms help them perform the essential functions of
life. The pancreas is an organ that regulates blood sugar levels. Consider Questions 5, 6, 7,
and 8:
a. Characterize and classify the important product the pancreas produces that aids in blood
sugar regulation. (2 pts)
b. Outline the process for how this important product is manufactured by the cell. (5 pts)
c. Diagram the regulatory process for the production of the product (ie. What starts/stops
the release?) (3 pts)
