Explanation:
Gram's staining is a differential staining technique that employs a primary stain like crystal violet and a counter stain like safranin along with the decolourizing agent alcohol and a mordant called the Gram's iodine.
Iodine is a mordant added after the primary stain. It fixes the stain by combining with it to enchance the staining ability. This forms an insoluble crystal violet iodine complex appearing purple under the microscope. These microorganisms are classified as Gram positive.
If addition of iodine is skipped, crystal violet is not fixed on the slide and the insoluble complex is not formed. The cells are decolourized by alcohol and are stained by the counter stain safranin making the Gram positive cells wrongly indentified as Gram negative due to its pink colouration. Thus, the slide will show all the cells as pink coloured Gram negative cells.

Answer:
The chart shows how well each beetle with each trait were able to survive in their environments, and Mutant 1 was clearly out living the other two, because as you can see mutant 2 has only last for at least one generation, while the non-mutated one lived a little longer. This is because Mutant 1 developed the trait that made its shell darker, and thus it's easier for them to hide from predators, and they were able to successfully pass on their genes to their offspring so now they can do the same.
