Scientists have found two leaf fossils that come from very different climates. The smooth-edged leaf is from a warm climate, and the toothed-edged leaf is from a forest in a cooler climate. If the toothed-edged fossil was found in the desert, what hypothesis could you draw from this information. The climate changed from cool forest to hot desert.

THe area was once covered by ice.

There was once snow in this desert.

The area was once under water.

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.)
