Patients being treated with a particular drug run the risk of being allergic to the drug. a patient's reaction to the drug is characterized by doctors as being hyperallergic, allergic, mildly allergic or not allergic, and these have probability values of 0.12, 0.28, 0.33, and 0.27 respectively. suppose nine people are administered the drug and assume that one patient's reaction is independent of another patient's. (a) find the probability that two patients exhibit no reaction. (b) find the probability that no patients are hypoallergenic, one patient is allergic, four patients are mildly allergic, and four patients exhibit no reaction.

C. gemstones they are the only non metallic mineral from the list.

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
