Ayoung woman decides to go for a hike in Yellowstone National Park on a summer day. She brings a water bottle, a protein bar, a hat, and some
sunscreen with her. She also brings her bear repellant. Before her hike, she has a good breakfast, including eggs, oatmeal, fruit, and orange juice.
At the beginning of her hike at 9 a.m., the day is cool, and she is wearing shorts, a T-shirt, and a light jacket. By noon, she has hiked five miles, and
it is 95°F and very sunny
Describe what cellular processes are occurring to the woman during the day.
• What occurs inside her body after she eats breakfast?
• What occurs inside her body as she starts her hike?
• What occurs inside her body as the day warms, and how might she respond to this?
• At noon, what may be occurring at a cellular and body level, and why?
Within your group, brainstorm and create a list of what may be occurring at both the cellular and body level for this woman and how
her system may respond to those signals. List only those processes that occur with your group's concept. Create your list in your
Engage Student Handout. Once your group has completed your list, raise your hands.
