A child is sliding down a slide at the playground.
Is the mechanical energy conserved? Why or why not?
The mechanical energy is conserved. There is as much KE at the end as there was PE at the beginning.
Mechanical energy is always conserved.
The mechanical energy isn't conserved. Some energy is lost to gravity.
The mechanical energy isn't conserved. Some energy is lost to friction.
please help!

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.)
