Answer:
c. Prevent crystal violet from leaving the cells
Explanation:
Gram Staining:
- Gram staining is a staining techniques used for the identification of bacteria in microbiological studies.
- Gram staining uses crystal violet as the primary stain. It complexes with the peptidoglycan cell wall of Gram positive bacteria giving them a purple color.
- An iodine mordant is also used that forms a crystal violet-iodine complex that fixes the crystal violet dye to the cell wall. This prevents the Gram positive cell walls from being decolorized by the application of alcohol.
- A counter stain, safranin is then applied that stains Gram negative bacteria pink.

Define key words/vocab words to solve.
Sometimes you have to define words in the definition too :-P
chemosynthesis - the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.
maybe easier to understand below:
Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent.
Hare population goes up which means more food for the lynx population. The lynx population then goes up as well.
It's the coordinated/directed movement towards the direction of light. Light is the stimulus
