Answer to Question 1

Crosslinking is the process of connecting polymer chains with covalent bonds. When this occurs, the total length of the polymer chains

Answer to Question 2

Addition polymerization will give branched polymers. This branching results from the loss of an atom, usually hydrogen, during the polymerization process which causes a free radical to form at the site where the hydrogen atom was previously located. This free radical is then able to bond with other free radicals, as on the end of a growing polymer chain, or with a monomer and begin a chain which grows as a branch off the main backbone. Condensation is less likely to branch because there is no mechanism that will create a reactive site in the middle of a chain.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
