"acquired characteristics are inherited".
"organisms change due to need or want"?
Scientists attempted to determine the evolutionary relationships between three different finch species, A , B , and C . In order to do this, they examined the physical characteristics and DNA of these species. DNA was extracted from all three species and analyzed using gel electrophoresis. The results are shown in the diagram. Which statement best describes the method used above to determine the evolutionary relationships between three species of finches?
Examine the structure of the beaks and compare them.
Observe behavioral and physical characteristics of all the finches and group them by similarities.
Obtain molecular evidence from all three species and identify similarities.
Compare common ancestors of all three of the species to see if they are the same.
A drug company has discovered an endangered plant that produces a chemical that might be used to cure cancer. A first step in developing this cancer cure could be to
preserve the habitat where the species is found
introduce a new plant species that will share the habitat of the plant
eliminate every species that eats this plant
harvest all of the plants of this species and use them to treat cancer patients
A plant was discovered that contained a compound that was found to have potential medicinal value. However, the plant is rare, so it is important to see if a related plant might also produce the same compound. The chart shows some characteristics of the plant and four possible relatives. Which plant in the chart would be selected as most similar to the medicinal plant?
A
B
C
D
Which chemicals are used to cut DNA into fragments for a gel electrophoresis procedure?
molecular bases
enzymes
hormones
ATP molecules
biology.
Several of the Galapagos Islands are inhabited by grasshoppers, beetles, flies, bees, and butterflies. Finches that feed on these consumers would have beaks adapted for
Which two finches would compete the least for food?
The diagram represents evolutionary pathways of seven groups of organisms alive today. Which two living species would be expected to have the most similar proteins?
A and C
B and C
E and F
H and M
Which statement would most likely be correct, based on the information in the diagram?
Species C had many variations and lived in a stable, unchanging environment.
Species D, C, and J are extinct.
Species F evolved from species D.
Species J had little variation and lived in a changing environment.
Which of the following would be the definition of a decomposer?
Animals that eat insects.
Organisms that feed on rocks, recycling the nutrients back into the ground.
Organisms that eat only pants
Things that feed on dead organisms, recycling the nutrients back into the ground.
What are renewable resources?
. Resources that are used faster than they form
resources that can replenish themselves over time
resources that formed over millions of years
resources that exist only in rural areas
Which level of the food chain is most affected by biomagnification?
Producers
primary consumers
secondary consumers
tertiary consumers
What is global warming
the normal temperature fluctuations of Earth's climate cycle
the melting of the polar ice caps
the trend of increasing temperatures on Earth
the changes in Earth's biosphere that affect the atmosphere
1. Why might an introduced animal species overrun native species in an ecosystem?
. Its population size is smaller than those of native species.
. It is more energy efficient, so it eats less food.
It is a predator of the native species.
It often has no natural enemies
Which 2 organisms would be able to reproduce and produce fertile offspring?
2 organisms in the same class
2 organisms in the same family
2 organisms in the same genus
2 organisms in the same species

Ink can be separated by a method of -----------------------------------------------
distillation
filtration
chromatography
sedimentation
Evolution is best defined as:
the process which organisms die.
the process which organisms change over time.
the process which organisms that are extinct become revived.
the process which non-living things fossilize.
What type of evidence is represented in the picture above:
Fossils
Vestigial Structures
DNA
Homologous Structures
What type of evidence is shown in this picture?
Fossils
Homologous Structures
Vestigial Structures
DNA
Adaptations are:
physical or behavioral tendencies.
physical or behavioral characteristics that help an organisms survive and reproduce.
physical or behavioral characteristics that do not help the organism in any way.
genetic mutations that have gone wrong.
Which scientist is known for his work that he did on the Galapagos Islands to develop his theory of natural selection?
Gregor Mendel
Charles Darwin
Anton Van Leewenhoek
Robert Brown
The process by which two populations of the same species become so different that they can no longer interbreed.
natural selection
artificial selection
speciation
fossilization
use or disuse
acquired characteristics are inherited
