1) Unicellular prokaryotic organisms: All prokaryotes are unicellular in nature, like different types of bacteria and cyanobacteria (blue green algae). They do not have membrane bound true nucleus. Genetic material present in prokaryotes are known as nucleiod.
Most of the methamphetamine abused in the United States is manufactured in âsuperlabsâ here or, more often, in Mexico. But the drug is also easily made in small clandestine laboratories, with relatively inexpensive over-the-counter ingredients such as pseudoephedrine, a common ingredient in cold medicines.ethamphetamine (also called meth, crystal, chalk, and ice, among other terms) is an extremely addictive stimulant drug that is chemically similar to amphetamine.
However, methamphetamine differs from amphetamine in that, at comparable doses, much greater amounts of the drug get into the brain, making it a more potent stimulant. It also has longer-lasting and more harmful effects on the central nervous system.ethamphetamine was developed early in the 20th century from its parent drug, amphetamine, and was used originally in nasal decongestants and bronchial inhalers.
