Why is frog development susceptible to minor environmental changes?

• A. They live a significant portion of their life in water

• B. They go through many developmental changes.

• C. They are not adapted to live in aquatic environments.

• D. Both A and B

What are the main factors or causes in the disruption of the frog's cellular processes?

• The disruptions are unexplained.

• Larval cysts disrupt the developmental cycle and pesticides lower white blood cell count.

• Water density and temperature extremes.

• Radiation and global warming.

The pesticide manufacturers have research which shows that their products do not cause deformities in frogs. Studies by independent researchers show a link between pesticides and frog deformities. How can these two results both be true?

• Manufacturer's tests were done in the absence of parasites.

• Different types of frogs were studied and had different responses to the chemicals.

• They cannot both be true. The independent researchers have made a mistake interpreting their results.

• They cannot both be true. The manufacturers are trying to fool the public into buying their pesticides.

Why should consumers read and follow directions on pesticide labels?

• To protect their own health

• To protect the health of amphibians like frogs

• To prevent pesticides from being washed into nearby streams and other waterways

• All of the above

How did tadpole white blood cell counts affect the number of deformities in the frogs?

• The less white blood cells the frogs had, the more deformities the frogs had.

• The less white blood cells the frogs had, the less deformities the frogs had.

• The number of white blood cells would fluctuate, and deformities would result during these periods.

• White blood cell counts had nothing to do with frog deformities

What impact does knowing what causes the deformities in the frogs have on the environment?

• Provides justification to eliminate trematode parasites from our bodies of water

• Provides evidence that we should not use pesticides since they are damaging the frogs

• Demonstrates that environmental systems are complex and interconnected, so we must seek complex solutions

• Does not make any difference
