Which option correctly matches each example with its area of motor behavior? A child’s balance improves as the child grows. A person adjusts posture after being bumped. A student permanently improves a tennis serve through practice. A researcher studies movement across all three of these situations.

In the event of a natural disaster here in the United States, the water supply might get interrupted, potentially forcing people to turn to possibly contaminated sources of water in lakes and streams for their drinking water needs. Assuming a disaster that has knocked out utilities (i.e., no electricity or natural gas supplies), suggest an approach one might take to treat water to remove possible contaminating microorganisms to help avoid getting sick, and explain what that approach would do to the microorganisms. Be specific: what impact would this approach have on removing or destroying potential pathogens? Do not just state “it kills them”, but explain why or how, including what structures or cellular components would be impacted.

Consider approaches you’ve studied for controlling (limiting or stopping) bacterial growth. Choose a control method not well covered on this test (e.g., something you studied but haven’t yet had a chance to share!), and describe how it works. If it helps you in writing this, briefly describe (a sentence or two) a scenario involving bacterial contamination or exposure, and then explain how you could use your control method to decontaminate/sanitize/sterilize/etc. microorganisms. What specific impact does this method have on the microorganisms? Do not just state “it kills them”, but explain how or why, including what structures or cellular components would be impacted.
