Biology Graphs

What conclusions can be drawn form this graph? (CO2 is Carbon Dioxide)

• Atmospheric carbon dioxide is responsible for global warming

• Atmospheric Carbon Dioxide Levels in parts per million have been rising since 1960

• Atmospheric Carbon Dioxide Levels in parts per million have been falling since 1960

• Atmospheric carbon dioxide levels have not meaningfully changed in the past several decades

The following two graphs show sea urchin availability and consumption by otters.

What trend and/or relationship do you see in both of these graphs?

• Larger urchins are found near Attu Island, and smaller urchin are rarely consumed near either island.

• Larger urchins are found in Amchitka, and smaller urchin are rarely consumed near either island.

• Similar sized urchins are found in both islands, and urchins are consumed evenly regardless of size.

• Similar sized urchins are found in both islands, and only small urchins are consumed.

What do these graphs suggests in regards to which sized urchins are preferred by otters?

• Otters prefer to eat small sea urchins.

• Otters prefer to eat mid-sized to large urchins.

• Otters do not have a preference for urchin size.

• Otters refuse to eat medium sized urchins.

This graph shows the relationship between the size of a sea urchin (diameter) and the thickness of its protective shell for two different species.

What does this graph reveal about sea urchins?

• Purple urchins have a greater thickness than red urchins.

• Red urchins have a greater thickness than purple urchins.

• Both urchins have the same thickness.

This graph shows the relationship between the size of a sea urchin (diameter) and the thickness of its protective shell for two different species.

How might the thickness of the urchin's shell impact the otters' choice of prey?

• Otters would prefer thinner shells, because they will be easier to open.

• Otters would prefer thicker shells, because they would be harder to open.

• Otters would prefer thicker shells, because they would be easier to open

• Otters would not have a preference based on shell thickness

What trends do you see in the graphs?

• Sea urchins are bigger in areas without sea otters.

• Sea urchins are smaller in areas without sea otters.

• The presence of sea otters does not seem to affect sea urchin size.

• Sea urchins are bigger in areas with sea otters

• The bacteria will be completely killed off if the antibiotics dosage is increased.

• The patient should have not taken the antibiotics again after day 5.

• The patient has become immune to the bacteria by day 10.

• The bacteria developed resistance to the antibiotics.

An analysis of DNA and RNA sequences can be used to classify organisms. A dendrogram, such as the one shown, is based on molecular data. It can be used to represent evolutionary relationships within a group of organisms that are hypothesized to have descended from a common ancestor. Which statement is best supported by the information in this dendrogram?

• Lesser pandas are more genetically similar to giant pandas than they are to raccoons.

• Brown bears are more genetically similar to giant pandas than they are to sun bears.

• Lesser pandas are more genetically similar to raccoons than they are to giant pandas.

• The bear species are all more genetically similar to dogs than they are to giant pandas.

In a graph showing the rate of photosynthesis at different light intensities, what does the plateau indicate?
