In her experiment, she creates 4 rooms at temperatures that vary by 5 degrees F. Each room gets 20 seedlings of the same species, which she grows on agar plates for 60 days. Once a day, she measures the length of each seedling's root. At the end of 60 days, she compares the length of the roots with the room temperature. She finds the room with the lowest temperature produced the longest roots. What is the independent variable in this study? • Temperature • Seedlings • Light • Root length 10. Which of the following can act as enzymes in the body? • Globular proteins • Lipase • Amylase • Glucagon 11. Which of the following is the carbohydrate monomer? • Disaccharide • Lactose • Monosaccharide • Thymine 12.
