What is the difference between mass and weight?

a. mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on the object.
b. weight is a measure of the amount of matter in an object, while mass is a measure of the force of gravity on the object.
c. mass is a measure of an object's inertial force, and weight is the force exerted by that object on other objects.
d. mass and weight are synonyms and ultimately describe the same principle.

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.)
