Think about a drop of water in the ocean. if it were to go through the whole hydrologic cycle, number the steps that would follow. 1. step 1 the groundwater flows into a river which empties back into the ocean. 2. step 2 the atmosphere is cooler, so the drop of water would change from a gas back to a liquid through condensation. 3. step 3 evaporation would change the drop of water to water vapor, a gas, which would rise into the atmosphere. 4. step 4 as more water vapor condenses into liquid, the drop of water will eventually drop to earth's surface as precipitation. 5. step 5 the drop of water falls to the ground as rain and is absorbed as ground

Which of the following scenarios is an example of the bottleneck effect? answers a in south africa, much of the afrikaner population is descended from a small number of dutch colonists. in this population, this is an unusually high frequency of pseudoxanthoma elasticum (pxe), an elastic tissue disorder. b four white-tailed deer are introduced to a park in finland. thirty years after their introduction scientists compare the genes in the population and find that there is no variation. c during the industrial revolution, london's air became filled with soot. as a result, birds started eating more of the lighter moths because they were easier to spot than their darker counterparts. over time, the moth population changed so that there were more darker moths than lighter ones. d 10% of the population of american alligators in an area have the recessive trait albinism. a massive flood results in the death of 80% of the population. of the remaining population, 60% have the recessive trait of albinism.
