Mountain lions with lots of variation because variation is important for species’ survival.

When injected, benzedrine, dexedrine, and methamphetamine increase the release of serotonin, norepinephrine, and dopamine in the brain. Benzedrine, dexedrine, and methamphetamine are examples of amphetamines. They are stimulants, which speed up the messages travelling between the brain and the body.

Answer:
B) stain only the thicker peptidoglycan cell walls
Explanation:
Gram staining is a technique which was developed by the Hans Christian Gram in 1884 to distinguish the bacterial strains. Based on the colour absorbed and retained by the bacteria, the bacteria are distinguished either as gram-positive or gram-negative.
He used a colour stain- crystal violet which is a positive dye and binds to the cell wall made of peptidoglycan. The crystal violet binds to the cell wall with the help of a mordant called iodine. If this dye retains inside and the cell appears purple then the cell is considered gram-positive else negative.
Thus, Option-B is correct.
