After World War II, people began living in suburban areas. How might the movement of people from cities to suburbs be related to the development of pesticides by chemists?

O Pesticides were needed in urban areas for pests that moved into abandoned apartments, such as ants, bees, and
other insects.
O Pesticides were used to help convert farmland into lawns and to rid new homes and neighborhoods of insects.
O Pesticides were needed to kill foreign species of insects that were carried into the country on the clothing and military
equipment of troops returning from war.
O Pesticides were developed in suburban factories, so the sale of pesticides was heavily promoted to bring more
money to the factories.

Bisphenol a (often called bpa) is a chemical found in products that people use every day, from water bottles to food containers to children's toys. unfortunately, bpa leaches out of its many products and makes its way into our bodies. what are the health effects of bpa exposure? ongoing research is finding that elevated exposure to bpa can affect a wide variety of developmental and physiological processes, but one of the first studies of bpa's health effects came about because of a simple mistake in the lab. at a laboratory at case western reserve university in 1998, geneticist patricia hunt was making a routine check of her female lab mice. as she extracted and examined developing eggs from the ovaries, she began to wonder what had gone wrong. she noticed that many of the eggs showed problems with their chromosomes, and some had irregular amounts of genetic material, which can lead to miscarriages and birth defects in mammals. she learned that a lab assistant had mistakenly washed the plastic mouse cages and water bottles with a harsh soap, releasing bpa from the plastic. knowing that bpa is an endocrine disruptor, a chemical that can enter organisms and mimic hormones, hunt set out to discover whether it had adversely affected her mice.
