50 points The Okefenokee Swamp in South Georgia is often subject to fires because of the ready availability of natural fuels, such as trees, woody shrubs, and peat. Drought aids these fires because the
vegetation that is present dries out and becomes more combustible. Does fire help maintain the stability of the Okefenokee Swamp ecosystem? Why or why not?

А. Fire helps maintain the swamp ecosystem by clearing out excessive vegetation and keeping out hardwood growth, which maintains the habitat for swamp animals.

B. Fire does not affect the stability of the swamp ecosystem because most fires in the swamp are not severe enough to be a factor in disrupting stability.

С. Fire does not affect the stability of the swamp ecosystem because the water in the swamp is still there to help put the fire out.

D .Fire helps maintain the stability of the swamp ecosystem since the fire does not affect the aquatic organisms that live there.

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.
