Biologists in louisiana have become concerned about cadmium levels in the water near new orleans and the probability that frogs
will die out. They performed an experiment on bullfrog tadpoles to determine how toxic cadmium is to bullfrogs. Suppose a small river with a population of 10,000 frogs becomes polluted with cadmium to a level of 3 mg per gallon per day. About how many bullfrogs would be expected to die?
The survival rate of bullfrogs increases as the amount of Cadmium decreases. This will happen because cadmium is a ubiquitous pollutant in aquatic environments. Cadmiun can alter organismal physiology and ecology affecting their growth and development.
They are going to the doctor because of his behavior which means they will analyze and study it at the doctor then see what they can do from there or "apply" what they need to.
Hope this helps! Would love brainliest trying to get to virtuoso thank you!
