SOL Review 16

The picture shows three columns of exposed rock that are within a three-kilometer area. According to this information, the dominant past environment has been – 

• arctic tundra

• shallow marine

• deciduous forest

• tropical desert

This organism is most closely related to animals in the Phylum Arthropoda, the phylum that contains beetles, because it has – 

• legs

• antennae

• jointed appendages

• an elongated body

Base your answer on the diagram below and on your knowledge of biology. The diagram illustrates the relationships between the organisms in a certain pond. In addition to sunlight, another factor needed to make this a self-sustaining ecosystem would be the presence of

• producers

• primary consumers

• decomposers

• higher order consumers

The diagram shows undisturbed 

sedimentary rock strata containing 

fossils. Which statement best 

summarizes the history of this area?

• The area was once a forest and was replaced by a freshwater lake.

• The area was once a freshwater lake and was replaced by a saltwater lake.

• The area was once a saltwater sea and later was replaced by a coniferous forest.

• The area was once a saltwater sea and later was replaced by a desert.

The difference in the above characteristics of flower species most likely resulted from – 

• parasitism, which did not harm the host species

• mutualism between different plant species

• adaptations in response to different selective pressures

• defensive mutations allowing concealment of species
