Answer to Question 1

A free radical is an atom or molecule which has at least one electron which is not paired with another electron. It is so reactive because the natural state of matter is for that unpaired electron to form a bond.

Answer to Question 2

Nylon is made through the condensation polymerization process. Water is a byproduct of the polymerization. After a certain point in the process, the reaction begins to slow because of the abundance of water. Continued reaction becomes increasingly more difficult and chain growth is halted. This gives shorter chain length and lower molecular weight. One method to overcome the overabundance of water in the reaction vessel is to apply a vacuum to the polymerization chamber. By removing the water from the reaction, the molecular weight can continue to grow.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).

Though “Krazy Glue” or “Super Glue” has the ability to seal small wounds, it is not recommended for this purpose since it contains many substances that should not enter the body through the skin, and may be harmful.

Studies show that systolic blood pressure can be significantly lowered by taking statins. In fact, the higher the patient's baseline blood pressure, the greater the effect of statins on his or her blood pressure.

As many as 20% of Americans have been infected by the fungus known as Histoplasmosis. While most people are asymptomatic or only have slight symptoms, infection can progress to a rapid and potentially fatal superinfection.

Computer programs are available that crosscheck a new drug's possible trade name with all other trade names currently available. These programs detect dangerous similarities between names and alert the manufacturer of the drug.
