Answer: Polychlorinated biphenyls (PCBs) are a group of manmade chemicals. They are oily liquids or solids, clear to yellow in color, with no smell or taste. PCBs are very stable mixtures that are resistant to extreme temperature and pressure. PCBs were used widely in electrical equipment like capacitors and transformers. They also were used in hydraulic fluids, heat transfer fluids, lubricants, and plasticizers. The primary company that made PCBs in the United States was Monsanto Inc., mainly using the name Aroclor. Commercial production of PCBs ended in 1977 because of health effects associated with exposure. In 1979, the U.S. Environmental Protection Agency (USEPA) banned the use of PCBs; however, PCBs are still present in many pre-1979 products.

Each enzyme is comprised of covalently linked amino acids...enzymes are proteins
Oligosaccharides consist of more than one monomer. Four-sugar oligosaccharides have four same or different monomers. In this case, two <span>four-sugar oligosaccharides consist of two glucose and two galactose monomers. Still, they are not identical. The sequence of monomers in each oligosaccharide may differ. Also, geometry and location of glycosidic linkages may vary. This two factors, separately or working together, affect the structure of oligosaccharides.</span>
Answer:
Chromosomes are a threadlike interrelation of nucleic acids along with protein that is found in the nucleus of most/more of living cells and organisms that carries genetic info in the form of genes.
Chromosomes are what give us our characteristics. In the process of reproducing, the father's DNA will travel through the sperm to the eggs. These eggs, being in the mother, will have her DNA as well. Combining these DNA strands, it can make the hair color of a child, the eye color, ethnicity, and skin color.
