We think that dwarfism in river birch might be a simple Mendelian trait. We have taken a pure breeding normal plant and crossed it with a a pure breeding dwarf plant. The resulting F1 plants were normal height. The F1 plants were selfed and the F2 data is presented below: Normal River Birch 814 Dwarf River Birch 252 Perform a chi square analysis on this data using the following hypothesis: The mode of inheritance for height in river birch is simple Mendelian. What is the calculated chi-square value

Nitrofurantoin used during the fifth week of pregnancy places the neonate at risk for which condition?

Using the periodic table, determine which material is most likely a good conductor

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.)
