Frog Dissection Questions?

• 1. Identify one simple machine in the frogs body. Explain how it works to help the frog. 2. Frogs are often seen at the surface of the water in a pond, motionless with only their external nares and eyes showing above water. Based on buoyancy, how do you think they accomplish this. 3. Frogs secrete a film of mucus on their skin. Based on viscosity, explain the purpose of the mucus. 4. Pesticides decrease the number of insects in and around crops and residential areas. Some pesticide will run off the land and make its way into the local watershed (streams, ponds, etc.) and contaminate the water within the frog's habitat. Discuss the direct and indirect impacts that pesticide use has on the health and well-being of a frog.
