Ascientist is studying a species of flagellated bacteria similar to the cell shown in the illustration. after examining many cells of this species using an electron microscope, she calculates that the average length of a cell is 2.2 micrometers. which scientific term best describes this finding?

Which statement is true about the cell theory? a) it is well-supported by evidence. b) it is unchangeable and permanent.

Here's one way to follow the scientific method. place the missing steps in the correct position in the process.

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.)
