1. As you read “The Bison are Back,” summarize each paragraph below. 2. Identify the main problem of the text.

3. Do you think the bison should be protected? Why or why not?

4. Brainstorm possible solutions to the problem. Highlight the solution that you think is the
most reasonable.

5. Make a decision-making model for the solution you thought was the most reasonable. Pick
two values you think are important to consider from p. 20 in your textbook and place them
in the table below.
*** Remember to list all possible positive and negative effects that could result. There is an example model on page 23.
6. Make a decision and state two reasons to support it.
7. How has your thinking changed about protecting the bison? Explain.

you must remain stopped until the stop signal is retracted and the red lights are turned off. approaching traffic in the opposite roadway of a divided highway shall not be required to stop, even if the school bus has the stop-arm extended and the alternately flashing warning signal lamps on.

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
