garri49 [273]

Answer:

Explanation:

According to my research on different cultural characteristics, I can say that based on the information provided within the question two reasons, Firstly this can be that the latino population includes many young adults, and healthy young adults have been known to repopulate faster. Secondly, latin america countries have a significantly higher fertility rate than the United States, and since the latinos in question are most likely migrants from latin america countries this can explain the high fertility rate among them.

What are PCB’s and where in the body do Tomcods store PCB chemicals?
olga55 [171]

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.
