Exploration Activity: Connecting Physics to Biology

Note: The exploration activity will be submitted through Blackboard, not the MasteringPhysics website, as a separate assignment. For further clarity, please consult your professor.

The energy we require to live comes from the chemically stored potential energy in food, which is transformed into other energy forms during the metabolism process.

What consequence awaits a person whose combined work and heat output is less than the energy consumed? What happens when the person’s work and heat output is greater than the energy consumed? Can an undernourished person perform extra work without extra food? Discuss and defend your answers.

Write a 5-paragraph essay connecting physical principles with biology. Include your responses to the questions above.

Exploration Activity: Understanding Radioactivity

Note: The exploration activity will be submitted through Blackboard, not the MasteringPhysics website, as a separate assignment. For further clarity, please consult your professor.

Throw ten coins onto a flat surface. Move aside all the coins that landed tails-up. Collect the remaining coins. After tossing them once again, remove all coins landing tails-up. Repeat this process until all the coins have been removed. Can you see how this relates to radioactive half-life? In units of “tosses”, what is the average half-life of 25 coins? 50 coins? 1 million coins?

Repeat the preceding activity, but use 10 dimes and 25 pennies. Let the dimes represent a radioactive isotope, such as carbon-14, while the pennies represent a nonradioactive isotope, such as carbon-12. Remove only the dimes when they land heads-up. Collect all the pennies and add them to the dimes that were heads-up. Does the number of pennies affect the behavior of the dimes? Someone gives you two sets of coins. The first set contains 10 dimes and 25 pennies. The second set contains 2 dimes and 25 pennies. Which set of coins has gone through a greater number of tosses? Which set provides the most “radioactivity” after a toss? Which set is analogous to a sample of once living ancient material?

Answer each question and summarize your results in a 2- to 3-page paper. Include a description of your experimental process and include a table of your data.
