You have gone into the field to take water samples from two lakes in your town.

You note the following observations:

Lake A contained many fish swimming in its waters.

Lake B had very few fish swimming in its waters, and a few dead fish floating on the water.

You return to your lab and take pH readings for each sample.

Think about how acids and bases would affect the water quality in the two lakes.

Which set of pH data would you expect to see based on your observations?

Lake A: pH = 4.5; Lake B: pH = 7.5

Lake A: pH = 8.3; Lake B: pH = 3.7

Lake A: pH = 6.6; Lake B: pH = 6.8

Lake A: pH = 10.2; Lake B: pH = 1.7

B is the answer.

List the advantages and disadavantages of the switch from persistent chlorinated hydrocarbon pesticides (such as ddt) to nonpersistent organophosphate pesicides. have the benefits of the switch outweighed the disadvantages? explain.

Be in this im starting a with you so if you want you can get a partner for this. but basically im going to assign you guys a biome and you have to have a big sheet paper and you will turn it into 4 squares. the top right square is will be a drawing square for a drawing you will make of your biome. the top left square is about the biomes plants and drawings of them. the bottom left square is about the biomes animals. the bottem rights square is about the description of the biome. leave a comment or an answer and i will assign biomes. if your request one thats the one you get. send me a link to the project and i will grade ! im not a teacher btw.

Do you think the gene eef1 alpha1 supports cell theory? explain your response.
