1. When environmental pollutants degrade, they may become more toxic than the original pollutant that was emitted.

True

False

Expert Solution

The given statement is TRUE, ie., When environmental pollutants degrade, they may become more toxic than the original pollutant that was emitted.Many organic compounds and some inorganic compounds may volatilize to some extent; this means that these compounds tend to evaporate at normal atmospheric temperatures and pressures when not contained. Common examples include the lighter components of gasoline such as benzene, which volatilize to a sufficient degree that they can be smelled when cars are refueling at filling stations without vapor control systems.These pollutants are suspected to cause cancer and other serious health effects, such as reproductive effects or birth defects, and adverse environmental effects.In 1970, HAPs were formally introduced into the United States Environmental Protection Agency Clean Air Act. It identifies HAPs as pollutants which present or may present, through inhalation or other routes of exposure, a threat of adverse human health effects or adverse environmental effects whether through ambient concentrations, bioaccumulation, deposition, or otherwise as a result of emissions to the air.

1. Why are aminoglycosides more selectively toxic to bacteria than human cells? (Be sure to be complete and specific in your answer to make it clear why these drugs are more toxic to bacterial cells than to human cells.) 2. Penicillins and cephalosporins are beta-lactam antibiotics. Plasmids coding for beta-lactamase enzymes make the bacterium resistant to these antibiotics. What do beta-lactamases do? 3. The malarial organism possesses the remnants of a chloroplast, called an apicoplast. How does tetracycline inhibit growth...

Question 1. An environmental scientist isolates a pollutant (compound X) from a factory’s effluent stream and dissolves it in water. Experiments are then conducted using liquid – liquid extraction to optimize its extraction. Using diethyl ether as the extracting phase, the following distribution ratios, D, are calculated as a function of pH: pH 2 4 6 8 10 12 D 0.008 0.8 39 76 75 76 Does compound X appear to have acidic functional groups, basic functional groups or both...

Structures in organisms (when no longer adequate for their original purpose) often become secondarily adapted for a different use. In the course of their evolutionary history, vertebrates have utilized three different "urinary" systems. Today, however, we only use one. What has happened to the other two? Why were they no longer adequate for mammalian needs? What do you think would happen to such vestigial structures if a secondary "use" did not arise? Why?

): Infants who cry easily may be more easily stimulated than others. This may be a sign of higher IQ. Child development researchers explored the relationship between the crying of infants four to ten days old and their later IQ test scores. A snap of a rubber band on the sole of the foot caused the infants to cry. The researchers recorded the crying and measured its intensity by the number of peaks in the most active 20 seconds. They...
