The high number of potential combinations from only four base pairs and the impact of small changes in the sequence of base pairs contributes to the diversity of proteins in an organism.

Big Idea 3: Living systems store, retrieve, transmit, and respond to information essential to life processes. The length of your response does not determine your score—a one-page written response containing accurate, succinct, yet detailed information can score the maximum amount of points, while other essays spanning three to four pages of vague, inaccurate materials may not earn any.

Short Free Response Practice Question 1 In a long-term project studying the interactions of several species of animals on an isolated island, scientists counted the number of individuals of each species visiting a site on the island over the course of several days, every summer for years. The peas that have only been germinating for one day are not as well developed. Part of being precise is presenting your answer in complete sentences. There are almost always easy points that you can earn. A description question might, for example, ask you to describe the results you would expect from an experiment. These long series of base pairs code for longer and more complex proteins that can differ in minor or very significant ways. I will be able to measure the amount of water drawn into the pipette by comparing where the water mark begins and where it ends. Use the time to be as precise as you can be for each subquestion. Short Free Response Practice Question 1 All living organisms contain genetic information that provides several functions inherent to the individual organism and the perpetuation of its species.

Here is a sample graph: C Key points to include: clear explanation of the graph and clear explanation of the significance of the results Here is a possible response: The graph shows that peas that have been germinating for three days consume more oxygen during a minute period than peas that have been germinating for one day.

Sex-linked X-linked inheritance. Begin with the separation of the messenger RNA from the DNA template and end with the release of the protein at the plasma membrane. Explain how the principles of gel electrophoresis allow for the separation of DNA fragments.

You should draw on your knowledge of this topic to answer the question. For example, a discussion question might ask you to discuss which of several theories offers the best explanation for a set of results.

Genetic variation is the raw material for evolution. To score points on this question, you must describe the experiment well and perhaps present the information in visual form.

Bacterial resistance to antibodies. While grammar and spelling are not assessed on the free-response portion, correct spellings of words and legible sentences will increase your chances of earning points. Procedure: I will place 20 peas that have been germinating for one day in one respirometer and 20 peas that have been germinating for three days in another respirometer. Describe the modern theory of evolution and discuss how it is supported by evidence from two of the following areas. I will record results measured by the graduated intervals on the pipette attached to the respirometer. Remember, the goal is not perfection. Use the organism that you used when completing this lab commonly germinating peas. Example Answer Key points to include: genes, base pairs, replication, proteins, diversity Here is a possible response: DNA is composed of only four different base pairs, and there is only one different base pair, uracil instead of thymine, in RNA. Therefore, these peas are not undergoing as much cellular respiration as the more developed peas that have been germinating for three days. Use the time to be as precise as you can be for each subquestion. A question that asks you to explain something is asking you to take something complicated or unclear and present it in simpler terms. The mechanism of action of restriction enzymes. B Key points to include: labels on each axis, regular intervals on the graph, a specific title on the graph, points plotted on the graph, and a line connecting the appropriate points. State the conclusions reached by Mendel in his work on the inheritance of characteristics.
