Acell is placed in a solution of 3% starch and 3% glucose. after several hours,
glucose is detected inside of the cell, but starch is not. explain how the
concentration gradient and the permeability of the cell membrane contributed to this
change.

Part a - which gene to compare? in this exercise, you will use the cytochrome c oxidase i (coi) gene to investigate relationships among salmon species. (this gene encodes a protein that functions in the mitochondrial electron transport chain.) you will compare the coi gene sequences from your salmon test samples to the standard sequences for each salmon species. in order for the coi gene to be useful for distinguishing among the different salmon species, which three statements must be true?
