A student reads the following questions and answers online: Q: How do plants get energy? A: Plants use carbon dioxide and water as their primary sources of energy. Q: Where does a plant’s biomass come from? A: Plants get most of the materials that make up their biomass (like cellulose, starch, etc.) from mycorrhizal fungi in the soil, so most of a plant’s biomass comes from the soil. Q: How to plants get nitrogen? A: Plants get the nitrogen they need by taking in N2 from the air and incorporating it into biological molecules. Correct each of these answers to accurately state how plants obtain energy, the material for their biomass, and nitrogen. Your answers do not need to be long, but should be clear and specific.

Refer tо the reseаrch study belоw tо аnswer questions 7-12. Dr. Rem studies sleep аnd sleep disorders. She is curious as to whether falling asleep in front of a television set causes people to fall asleep more slowly than falling asleep without watching TV. She recruits a sample of 60 women and creates three conditions. All participants come to the sleep lab for three nights in a row and experience all three conditions. In the first condition (A), participants fall asleep in front of a television that is off. In the second condition (B), participants fall asleep in front of a television that is turned on to a 24-hour news channel. In the third condition (C), participants fall asleep in front of a television that is turned on to the same 24-hour news channel but is muted. Participants sleep in the same bed each night. With the use of an electroencephalograph (EEG; a physiological measure that measures electrical activity in the brain), the researcher measures how long it takes participants to fall asleep each night. What is the dependent variable?
