Discussion: Helping Harry Meet Sally In Part 1 (Chapter 10) of Unit 6 you learned about Attraction and Relationships. Your friend Harry has a crush on Sally, but she barely knows he is alive. Both are PSYC majors here at MGA. What advice could you give to Harry to make him appear more attractive to Sally, based on the principles of (a) proximity and (b) similarity in terms of liking and attraction? (4 points) Sally goes to the gym on Tuesdays and Thursdays, where she spends about 45 minutes on the treadmill. Based on Schacter's 2-factor theory and the findings from Aron and Dutton's Bridge Study, how might you advise Harry to use this to his advantage (without being a stalker...). Here I'm looking to see if you understand Schacter's 2-factor theory and can correctly apply it, along with the results of the bridge study, to help Harry become more appealing to Sally. You do not have to re-hash the theory or study details – it's the application that is important. (4 points)

Question 25 Anabaena is a cyanobacterium with two types of cells. One type of cell can carry out photosynthesis and the other type can carry out nitrogen fixation. However, the oxygen produced by photosynthesis inhibits the enzymes for nitrogen fixation. Which structural characteristic allows the nitrogen-fixing cells to continue to function? Plasma membranes that are impermeable to nitrogen Specialized cells called heterocysts, which have cell walls that restrict the entry of oxygen Modified plasma membranes that are impermeable to both oxygen and nitrogen Cell walls that are impermeable to both oxygen and nitrogen Question 26 Which of the following statements correctly describes exotoxins and endotoxins produced by various bacteria? Endotoxins are secreted into the environment while the bacteria is still alive Exotoxins are components of the outer membrane of the bacteria that produce them Exotoxins are secreted into the environment while the bacteria is still alive Exotoxins are only released into the environment when the bacteria dies and their cell walls break down 1 pts 1 pts
