After crystal violet staining, the Gram-positive bacteria may appear dark blue or violet. The cell wall of gram positive bacteria have thick peptidoglycan layer, thus it retains the crystal violet stain compared to gram negative bacteria.
Hope this helps! Have a good day!
The sugar would leave the cell or water molecules would come into the cell
IV only
Plate IV will only have the trangenic E Coli hence will have the highest percentage of bacteria that are expected to produce insulin.
Explanation:
The transgenic <em>E. coli </em>will have taken up the plasmid with the insulin and <em>amp</em> genes hence they will be able to survive and grow in amplicilin antibiotic.
In plate IV, the wild type <em>E. coli</em> will be eliminated by the antibiotic (because they do not have the gene for resistance) hence providing no competition for resources, in the agar, with the transgenic <em>E coli</em>. This will ensure optimal growth for the transgenic <em>E coli</em> even, than in plate III, producing highest percentage of insulin.

Answer:
If the transgenic salmon escapes from their pens into the ocean population there are chances that they would compete with the wild salmons for food and space. They may also bring new diseases and changes to the food webs and ecosystem of the ocean.
Explanation:
A transgenic organism or genetically modified organism is the one that undergoes alternation through recombinant DNA technology.
No, I do not think that FDA should approve Aquabounty of growing and selling transgenic salmon since there is higher chance that they may interfere and disturb with the ecosystem and might also bring new diseases.
