the students in mr. c's class were studying climate change and were doing a lab experiment to find out more about rising sea
level. they were given two clear identical containers with clay (representing land). eight ice cubes were added on top of the clay
in container a representing greenland and antarctic ice sheets water was added to the container up the the land (not above it).
eight ice cubes were added to the bottom of the container b(not on the clay) representing ice in the arctic water was added to
the container up the land (not above it). measurement of water was taken in for both containers. a heat lamp was then placed
above each container to melt the ice. measurement was taken again at the end of the experiment when all the ice was melted.
what can you infer was the result?
a) container a showed an increase in water level
b) container b showed an increase in water level
c) both containers showed an increase in water level
d) neither containers showed an increase in water level

Over the past 60 years, many amphibian species have experienced significant population declines and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. chytridiomycosis is a fungal disease first identified in 1998 as a cause of massive amphibian deaths. in some severely impacted populations, a few individuals have survived, perhaps because of some natural resistance. if these resistant individuals continue to survive and prosper, new resistant populations might emerge. this would be an example of the founder effect artificial selection genetic drift natural selection sexual selection
