These moths are all the same species. The differences between their wings is an example of ________________
Natural Selection
Variation
An acquired trait
Extinction
The chart shows that species B and C have the fewest amino acid differences for a protein among four species. What does this suggest about their evolutionary relationship?
They are more closely related to each other than to the other species
They evolved at a faster rate compared to other species
They share a developmental similarity not observed in the other species
They do not share a common ancestor with the other species
Which of the following observations best supports the conclusion that two animal species evolved from a common ancestor in recent geological history?
The species are both herbivores.
The species both obtain oxygen from the air.
The species live in the same environment.
The species have similar bone structure.
Millions of years ago, a small population of birds lived on the Hawaiian Islands. Over time, this population evolved into more than 54 separate species, each with different colors, beak shapes, and food sources.
Which of the following best explains why the original population of birds evolved into so many different species?
The bird population moved into and adapted to many different environments on the Hawaiian Islands.
Many of the birds were killed each time a volcano erupted on the Hawaiian Islands.
The Hawaiian Islands had few predator species to decrease the lifespan of the birds.
The climate of the Hawaiian Islands rarely changed, which helped the bird population increase in size.
The figure shows the limbs of several different organisms. Which term describes these structures?
homologous
analogous
vestigial
Some organisms have remnants of a structure that may have had an important function for an ancestor, but serves no clear function in the modern species. Which term describes these structures?
homologous
analogous
vestigial
How would you expect the population of beetles shown in this figure to change over time due to natural selection?
Over time the percentage of striped-winged beetles will increase.
Over time the percentage of dark-winged beetles will increase.
The dark-winged beetles will adapt to have striped wings.
The dark-winged beetles will eat the striped-winged beetles.
Individual organisms evolve their genes to best fit their environment.
True
False
Which of the following can be used to study the early development of organisms to figure out similiarities to other species that cannot be seen in adult form?
Ethology
Embryology
Biochemistry
Anatomy
How would you best define a selective advantage?
The trait allows the organism to attract more mates more often
The trait allows the organism to spot predators easier
The trait causes the organism to require more food in order to survive
The trait causes the organism to require less food in order to survive
The movement of genes into and out of a gene pool is
Gene Flow
Extinction
Random Mating
Emigration
What is the human appendix an example of?
Analogous Structure
Homologous Structure
Extinction
Vestigial Structure
A butterfly wing and a bird wing are structures that are
homologous
analogous
vestigial
The wings of a flightless bird, such as an ostrich are considered
homologous structures
analogous structures
vestigial structures
The forearms of a bat and the forearms of a human are structures that are
homologous
analogous
vestigial
An organisms evolutionary fitness is measured by
how much they eat
where they live
their ability to survive and reproduce
Which on the these fossils is least ancient?
Which Nitrogen bases go together?
Adenine and Cytosine
Adenine and Thymine
Cytosine and Guanine
Thymine and Guanine
Steps or rungs of ladder, are made up of:
Nitrogen containing bases that connect in center by weak hydrogen bonds.
Nitrogen containing bases that connect in the center by carbohydrate bonds
Nitrogen containing bases that connect in the center by weak phosphate bonds
Nitrogen containing bases that connect in the center by strong phosphate bonds
ATG GGA ACT CCA
When lions prey on a herd of antelopes, some antelopes are killed and some escape. Which part of Darwin’s concept of natural selection might be used to describe this situation?
reproductive isolation
descent with modification
acquired characteristics
survival of the fittest
Which of the following is an example of natural selection?
Bald Eagles are hunted until near extinction, population recovers.
Small group of iguanas floats to an island, starts a new population.
Red fox pups are more likely to survive in a snowy environment if they are born white.
Farmer chooses seeds from largest apples to plant next year. This results in larger apples from year to year.
