In the 1990's, biologists studied the alligator population in lake apopka, florida. this lake experienced a chemical spill of the pesticide dicofol in 1980, and researchers wanted determine the effects of the pollution on organisms in the area. dicofol is a chemical that mimics female reproductive hormones in vertebrates. the pesticide mainly affects the sexual development of the males, and the number of fertile males lake apopke is significantly lower than in neighboring populations. what is a potential long-term effect of dicofol on the population of alligators in lake apopka, florida?

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
