The correct order of steps in a gram staining procedure is:
(4) the specimen is treated with a stain called crystal violet.
(1) iodine is added as a fixative or mordant.
(3) the specimen is flushed with alcohol to dehydrate peptidoglycans and trap the stain.
(2) the specimen is treated with a stain such as safranin or fuchsin (a pink stain)
Gram staining is a common staining technique which helps to classify the bacteria into two categories: Gram positive and Gram negative. Gram positive bacteria appear violet in color and Gram negative bacteria appear to be pink. This color difference appears due to the difference in the bacterial cell walls.

A molecule is a group of atoms bonded together. It represents the smallest fundamental unit of a chemical compound that can participate in a chemical reaction.
The red balls denote the hydrogen and black balls denote the carbon. He could make a macromolecule which is made up of carbon and hydrogen only.
Depending on the ecosystem, various things could happen. For example, if you introduced it to a forest/mountain area (Northern USA) a large cycle would change. Within 15 years, the mountain lions would prey on deer, mice and rabbits. The decrease in those populations would lead to an increase in plant wildlife. The variety in new plants could bring new animals like wild bison or even beavers.
