Use the image above to help answer this question. Dark black lines represent rivers. A rare toxic chemical polluted a lake in Wyoming. Many years later scientists discovered that a city in Kansas, 1000 miles away from the toxic spill, was polluted with the same rare toxic chemical. Scientists believe that the toxic chemical found in the Kansas well was the result of the toxic spill that occurred 1000 miles away. The people in Kansas were very confused about the scientist’s discovery. How could this be possible since the well was so far away from the lake or any river?
A. Pollution traveled through the surface water to reach the unsaturated zone.
B. Both locations where toxic pollution was found were along the same river.
C. The air became polluted and the wind carried the pollution to the well.
D. Both locations are in the same watershed.

Texas bluebonnet plants seen in this photo are an example of which ecological unit?

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)
