3. A survey of animal life in a pond suggests that a native fish species no longer inhabits the pond. The biologist leading the survey hypothesizes that the pond has
been made more acidic by acid precipitation. She thinks that this acidity has made
the pond uninhabitable by this fish species. The biologist has enlisted a chemist to
help her analyze the situation and decide whether her hypothesis is supportable
a. What is the first chemical test the chemist should perform to help the biologist
test her hypothesis? (0.5 point)
Think about the biologist's assertions about a change in the pond water

Now it's your turn to investigate human impact around the world. grab your virtual lab coat and put on your environmental science hat. you will be taking a trip around the globe to explore three locations. at each location, you will investigate the cause and effect relationships of deforestation, desertification, and urbanization. you will also gather evidence of how these factors have impacted the environment over time

(drag each tile to the correct identify which questions can be answered by what can be answered by science or which cannot. -is it right or wrong to use genetic engineering to produce new food products? -what are the most common social settings that tend to produce accomplished artists? -if a new gene is added to the genome of a tomato species, will that species be more resistant to insects? -should humans use biotechnology to bring extinct organisms from the fossil record back to life? -do the types of organisms found in the fossil record appear in consistent sequences in different parts of the world? -are michelangelo's paintings more impressive than rembrandt's?
