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.

This is the amino acid cysteine. circle the amine group, put a box aroundthe carboxylic acid group and use a different colored pencil/pen to circle the sidechain (r group). h o | ||nh2— c- c-oh | ch2 | sh

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
