1. Given that the total magnification for the Anabaena photomicrograph above is 400X, and the magnification of the eubacterial cells in Exercise 1 (above) is 1000X, are these Anabaena larger or smaller than the eubacteria? Approximately how much larger/smaller are they?   2. What is the mechanism of action of Crystal Violet (i.e. what does it do to the cells and how does it do it)? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a. CV turns only Gram positive cells purple by interacting with the cells' peptidoglycan. Gram negative cells do not change colour. b. CV turns all cells purple by interacting with the cells' peptidoglycan. c. CV turns all cells pink by interacting with the cells' peptidoglycan. d. CV turns all cells purple by interacting with the hydrophobic layers in the cell membrane. e. CV turns all cells pink by interacting with the hydrophobic layers in the cell membrane.   3.
