Separate your four fossils and label them Fossils A, B, C, and D. Using your magnifying glass, closely examine each fossil. Complete the table to record your observations, which should include these details: Predicted kingdom: Classify the fossil based on whether it shows the characteristics of a plant, animal, or fungi. Physical characteristics: Note the shape, patterns, and any other physical features of the fossils. Predictions about its environment: Based on the features of the fossil, what type of environment did the organism live in? Was it an aquatic organism or a land organism? Did it require a hot or cold climate? Similar living organisms: Try to identify a present-day organism that resembles your fossil. What characteristics do the two organisms share? What characteristics are different?

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.

Recent research by marine biologists suggests that bottlenose dolphins have names for themselves. scientists played sounds they had identified as the names of particular dolphins, putting them through a synthesizer so that they did not sound like the voices of particular dolphins. the researchers found that dolphins would respond to the names of other dolphins that they were related to or associated with, but they ignored the names of strangers. this discovery suggests a much greater degree of self-awareness in aquatic mammals than was previously suspected. if this research holds up, what does it suggest about dolphins?
