What would happen to the solute potential when the molar concentration of the solute is increased (justify with equation)? WHY? What would happen to the solute potential when Temperature is increased (justify with equation)? WHY? What would happen to the solute potential when the dissolved substance is glucose vs. NaCl (justify with equation)? WHY? Why is water potential important for plants? Predict what would happen to plant and animal cells placed in 0.0M and 4.0M concentration solutions.

Why does decomposition of a dead animal happen in terms of energy? What would happen if we increase temperature? Why do we freeze food? Explain the process of energy coupling. Give an example. What would be the overall change in free energy if an enzyme where to couple the energy released from ATP to the production of L-glutamine from L-glutamic acid and ammonia? Would the reaction be spontaneous? What does spontaneous mean? Explain why plant cells need light energy to build sugar (in terms of energy).

Suppose that every year there are 50 falcons born and 30 falcons that die. a. What is the population growth rate (include units)? Interpret the value. b. What is the per capita growth rate of the falcons over a year? Interpret the value. c. Fill in the table and the construct a graph. d. Find the average rate of change for the falcon population from 2013 to 2018 (include units). Interpret the value. Year Population 2013 2014 2015 2016 2017 2018

###### "Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."
— Christopher R., University of Rhode Island '15, Course Hero Intern

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
