Chapter 48, Problem 1DAA
Summary Introduction

To determine: The common sex in offspring of women with less than one microgram per milliliter of PCB in serum.

Concept introduction:

Imbalance in sex ratio may arise as an effect of various factors such as natural factors, exposure to various contaminated chemicals, pesticides, and other environmental contaminants. Polychlorinated Biphenyls (PCBs) are widespread environmental contaminants that possess teratogenic and oncogenic properties. These chemicals increase the male/female ratio. The maternal contamination with PCBs is also connected with low birth weight and shorter height in males.

Though it has been banned for use in baby bottles, BPA is still widely used to manufacture other plastic items and epoxies (such as the coating on the inside of metal cans of food). BPA-free plastics are often manufactured with a related compound, bisphenol S (BPS), which has effects similar to BPA. Imagine you are part of a group lobbying for increased control of BPA and BPS in manufactured products. How would you best summarize the results of this study to help support your case?   A. I read a study once that said BPA was bad.   B. A 1998 study from Case Western University proved that BPA causes birth defects.   C. A 1998 study found that increasing exposure to BPA-leaching plastic sources increased the percentage of abnormalities in mouse oocytes, which could lead to an increased risk of birth defects.   D. A 1998 study found that even the smallest exposure to BPA-leaching plastics causes a high percentage of abnormalities in mouse oocytes, which could lead…

What is a potential role of methanogens in global warming?   Methanogens produce methane, which traps more heat than carbon dioxide and may contribute to global warming. Methanogens convert carbon dioxide into methane, removing carbon dioxide from the atmosphere and effectively decreasing global warming. The methane that methanogens produce during sludge digestion of wastewater treatment is burned so that it does not contribute to global warning. Methanogens convert methane gas produced by organic waste into carbon dioxide, decreasing global warming.
