Examine the graph that shows the changes in biodiversity over the past 500 million years. Analyze the graph at each of the yellow
triangles. Select the options below that correspond to the events occurring at the yellow triangles. Select ALL that apply.
A)
B)
C)
The change in biodiversity was most stable at the times indicated by the
yellow triangles.
There have been five mass extinction events, with the earliest occurring at
450 million years ago.
Species were evolving faster than the extinction rates, resulting in new
species forming quickly over time.
Humans were altering the environment too quickly with deforestation and
climate change, resulting in many lost species in a short period of time.
The environment was changing faster than the species were adapted at the
time points labeled by the yellow triangles, resulting in a loss of species.

carrying disease have moved further north as global temperatures have increased. Which information would be most useful to their investigation?
O A. Meteorologists' annual temperatures of all the major cities in the US for the last ten years.
O B. Population data from the CDC that ranges over several years for mosquitoes that spread disease.
o
C. A report from the Center for Disease Control (CDC) of mosquito spread diseases and their symptoms.
