Relationships and Biodiversity Lab

When comparing characteristics of two organisms, which evidence would be considered the strongest for supporting a possible evolutionary relationship?

• The two organisms are the same color.

• The two organisms are the same height.

• The two organisms produce many of the same proteins.

• The two organisms are found in the same locations.

Why would scientists want to find other plants similar to an important medicinal plant?

• The important plant is very slow growing

• There are very few specimans of the important plant

• There is high demand for the important plant

• All of these could be true

A laboratory setup that can be used to provide information about relationships between four plant species is represented in the picture shown. This setup is part of the technique known as

• electrophoresis

• biological staining

• dissection

• chromatograph

Protein sequences in one organism that resemble those of another suggest a

• coincidence

• lack of evolutionary relationship

• great number of mutations

• shared common ancestor
