Answer the following question given this paragraph: 1.5 Homeostasis Homeostasis is the activity of cells throughout the body to maintain the physiological state within a narrow range that is compatible with life. Homeostasis is regulated by negative feedback loops and, much less frequently, by positive feedback loops. Both have the same components of a stimulus, sensor, control center, and effector; however, negative feedback loops work to prevent an excessive response to the stimulus, whereas positive feedback loops intensify the response until an end point is reached. Q: What intensifies the response during homeostasis? Choices: - pressure loops - pure loops - negative feedback loops - positive feedback loops A:
positive feedback loops

Answer the following question given this paragraph: Potential energy is the energy stored in an object because of its position or shape. It includes gravitational potential energy and elastic potential energy. Gravitational potential energy depends on an object's weight and height above the ground. Q: What type of energy is stored in an object because of its position or shape? Choices: - magnetic - mechanical - kinetic - potential A:
potential
