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.
