A queen honeybee can lay up to 2,000 eggs in one day. This is an example of overpopulation. One benefit to laying so many eggs is to-
increase competition among honeybees for finding nectar
increase the chance of honeybees to survive and repoduce
increase the amount of honey produced for human consumption
decrease competition among honeybees so bumblebees can share resources
Okapi are strange animals that look like a combination of a giraffe and a zebra. They live in the Democratic Republic of Congo, where it's very hot and predators, such as leopards, are always lurking. The okapi use their 14-18 inch-long tongues to wash their eyes and ears to better see and hear the leopards in the dry, sandy environment. The features of the okapi are evidence of natural selection because the adaptation -
causes an increased rate of extinction due to eye infections
shows DNA mutations do not increase the survival of organisms with variations
helps individuals compete for survival to pass down traits through their DNA
creates a disadvantage which decreases the organisms chances for survival
According to evolution, what happens to the frequency of traits in a population of species over time?
The frequency of traits randomly changes
The frequency of traits never changes
The frequency of advantageous traits increases over time
The frequency of advantageous traits decreases over time
What is evolution?
An idea that all species are related and change gradually over time
it is a fight between species
An idea that all organisms are alike
Man came from gorillas
Which of the following is NOT a type of evidence of evolution?
Fossil record
DNA evidence
Embryology
Asteroids
The science that investigates the development of organisms from fertilized egg to time of birth or hatching.
Ecology
fossil records
homologous strcutures
embryonic development
Random changes in a DNA sequence, which may or may not impact the organism and be considered an adaptation, are called
migrations
mutations
genetic drift
natural selection
A hurricane swept through a beach ecosystem, wiping out all organisms in its path. The gene frequency in the area will be impacted for future generations because of this; this phenomenon is known as
gene migration
gene mutation
genetic drift
natural selection
Which of the following is an accurate statement regarding DNA comparison as evidence for evolution.
Species with a more distant common ancestor have more similarities in gene sequences.
Species with a more recent common ancestor have more similarities in gene sequences.
DNA comparison is not totally accurate or useful in determining common ancestor's between species.
Which does NOT increase genetic variation?
Mutations
Gene flow
Mitosis
Crossing over
When members of one population migrate to another they create
Gene pool
Gene flow
Genotype
Genetic Drift
The image shows peppered moth variants. What would be most likely to happen to these moths in a forest made of white birch trees?
Both variations would survive and reproduce in equal numbers
The light variant would be more successful
The dark variant would be more successful
Nothing at all
Which of the following was NOT present in earth's early atmosphere
Carbon Dioxide
Nitrogen

Ammonia
Process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do.
Transformational theory
Theory of natural selection
Punctuated equilibrium
Gradualism
Blue catfish are going extinct. A dam in a lake full of blue catfish bursts due to poor engineering and kills some of the blue catfish. This is an example of:
Natural Selection
Gene Flow
Mutation
Genetic Drift
Which of the following can be determined by observing the embryos shown in the diagram

The organisms belong to the same genus.
The organisms are native to the same geographic areas.
The organisms will grow into anatomically similar adults.
The Endosymbiotic Theory explains
the origin of prokaryotes
how bacteria lives
the origin of eukaryotes
how species develop
Which of these is the best is the best definition of adaptive radiation?
The process by which a species changes to better fill an available niche.
The process by which a single species evolves into many new species to fill available niches.
The process by which a species becomes better suited for a niche than another forcing it to specialize or go extinct.
none of these are definitions of adaptive radiation.
Which of these is the best definition of biogeography?
The study of how and why plants and animals live where they do.
The study of how and why plants affect each other and the environment.
The study of how and why plants evolve to compensate for changes in habitats.
None of these are definitions of biogeography.

A bumble bee has just enough mass to pull down and open up the snapdragon flower to get to the nectar inside. Other insects cannot do this. This adaptation is an example of:
convergent evolution
co-evolution
divergent evolution
speciation
Which best describes punctuated equilibrium?
Speciation occurs due to natural selection
Speciation occurs due to isolation
Speciation occurs slowly in geologic time, followed by long periods with very fast evolutionary change.
Speciation occurs suddenly and rapidly in geologic time, followed by long periods with little evolutionary change.
The Miller-Urey experiment of 1953 was designed to test the hypothesis that lightning supplied the energy needed to turn atmospheric gases into organic molecules such as amino acids. Which of the following describes why the Miller-Urey theory is widely accepted today?
Amino acids spontaneously form from molecules in the atmosphere today.
Organic molecules are present today in extremely high concentrations.
The process of synthesizing organic molecules from a mixture of gases has been successfully modeled in the laboratory.
No other alternative hypotheses have been introduced.

Comparing embryological development of different species
Biochemical Evidence
Comparing DNA and amino acid sequences of different species
Vestigial Structures
Structures in the body of an organism that no longer work.
Which of the following statements makes an accurate correlation between stages of hominid evolution?
The brain increased in size which resulted in hominids developing tools.
The brain decreased in size allowing for hominids to use tools.
As the brain decreased in size the skull increased in size.
Language developed as a result of increasing the size of the skull.
Scientists have found evidence that about 2.4 million years ago a gene regulating jaw muscles mutated and may have led to the more graceful human jaw we see today. The diagram below shows the skulls of 3 hominid species.
Which statement below most closely explains the link between jaw size and hominid evolution?
The jaws of hominids changed over time due to a change in brain size.

The jaws of hominids evolved to be larger and more protruding over time.
