Would it be easier for an investigator to change the outcome of differentiation if a cell used cytoplasmic determinants or induction to produce specialized daughter cells? see section 21.1 (page 420) . would it be easier for an investigator to change the outcome of differentiation if a cell used cytoplasmic determinants or induction to produce specialized daughter cells? see section 21.1 (page 420) . induction, because this could be easily changed by changing the cell's environment. cytoplasmic determinants, since it is easy to change the composition of a cell's cytoplasm induction, because it is easy to change the concentration of a cell's cytoplasm cytoplasmic determinants, because these could be easily changed by changing the cell's environment.

All living organisms are composed of a. only one cell. b. at least 100 cells. c. at least three cells. d. one or more cells.

Astudent observes a star from two positions of earth in its orbit, in summer and winter, and measures the change in the position of the star. which of these can be best calculated by this method?

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.)
