Use the ecological footprint calculator( https://www.footprintcalculator.org/home/en) to determine how many Earths we would need to live sustainably if everyone lived as you did. You may be surprised. According to the Conversation Ecology textbook, we would need four Earths if everyone lived as the average American did! Next, try the questionnaire again and make one change that you think will reduce your footprint. Then change this parameter back to its original value and try making a different change. Keep track of your results and try this for three different aspects of your lifestyle. What three changes did you make, and which one had the greatest effect on your ecological footprint? Why do you think that this lifestyle change had such a big effect? Is this a realistic change that you might be able to implement soon? Why or why not?

Define the characteristics that distinguish animals from other clades of Eukarya. Explain the relationships between motility, heterotrophy, and the evolution of elaborate nervous and sensory systems.

Compare and contrast the roles of cellulose microfibrils and hemicellulose in maintaining cell wall organization and preventing cell expansion.

Briefly outline the cycle by which energy is stored in and released from ATP. Discuss how ATP is critically important to cellular chemical processes. Describe the specific mechanisms of enzyme function. Pick a specific enzyme and describe its function and the importance of that function to life. Discuss how the loss of that enzyme would disrupt living processes.
