Uranium is mined in Niger to produce electricity. The residents of Niger are concerned because uranium mining produces cancer-causing radioactive wastes that enter the groundwater they drink. The table below shows the number of cancer patients in the Niger mining community between 1958 and 1974:

Year Fatalities
1958 9
1962 10
1966 10
1970 50
1974 67

Based on the table, which of these is the most likely year when uranium mining was first done in Niger?

I did the test and picked answer C, but it was marked wrong. Is this actually answer correct?

Astructure that is found in a plant cell and not in an animal cell is a ? central vacuole mitochondrion nucleus ribosome

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.)
