Answer to Question 1

LDPE because it is not crystalline like HDPE, which allows for the free radicals to recombine more easily and can move to allow polymers to join together.

Answer to Question 2

The plastic resin is the matrix in these composites and its purpose is to bond the fibers together, give shape to the part, and protect the fibers from adverse environmental conditions.

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).
