Answer:
This is an example of Harrison's central nervous system working closely with his autonomic nervous system to give him energy and awareness to escape.
Explanation:
Harrison interprets the presence of the group of teenagers as an imminent danger and so he is on the run, which corresponds to a set of reactions that are triggered in the human body when a danger is around. At this point, the central nervous system and the subtonic nervous system are working together to get the adrenaline in Harrison's body to rise to a level that allows him to escape the group of teenagers. The central nervous system was then responsible for receiving and processing information that indicates to Harrison that he may be in danger. On the other hand, the autonomic nervous system is responsible for regulating the body's involuntary responses, being responsible for controlling various vital functions and at this time for the release of adrenaline in response to the dangerous situation.

The best answer is A. The purpose of the cell wall is to hold the cell in a specific shape, usually rectangular or square. For example, a plant cell's wall keeps it rigid so that the plant can stand up.
If the cell does not have a wall, it can easily change shape to accommodate for things coming in and out of the cell.
Hope this helps!
Answer:
Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range.
