B.
A small portion of a population that is geographically isolated from the rest of the population runs the risk of decreased
A. genetic drift
B. natural selection
C. mutation rate
D. revolution
A.
What is Natural Selection?
The environment exerts pressure on a population to change and nature selected those with the best traits to survive.
Give an example of homologous structures.
human arms, bat wings, and dolphin flippers (same bones, different shapes and sizes for different functions)
structures that we have, but no longer use/need. (whale hip/leg bones)
All living things are classified using taxonomy. The system used to name the species is Binomial Nomenclature in which they use
A. Genus name and species name
B. The phylum name and order name
C. Domain name and kingdom name
D. Family name and order name
A.
New Blue Jays move into the population who have a different hue of blue than the Blue Jays. What mechanism of evolution is this?
Gene flow
In regards to how species changed over time, Lamarck and Darwin had contrasting theories. Which of the following statements is incorrectly associated with the theorist?
A. Lamarck --- organisms had the ability to change their physical characteristics.
B. Darwin’s --- in a population of one type organisms, only the fittest will survive in the environment.
C. Lamarck --- species could become extinct if they were not well enough adapted to their environment.
D. Darwin --- there is variation within a population or species resulting in some organisms better suited to their environment than others.
C.
Two organisms, such as bats and insects are not related, but they both have wings because they live in similar environments. What are these structures called?
Analogous Structures
How can two populations of the same squirrel species become two different species?
geographic isolation, been apart too long, too many differences that they cannot breed anymore
The order of taxonomy from broadest to most specific is..
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
In a species of frogs, there is a new color that pops up into the population. What mechanism of evolution is this?
mutation
Describe what "fitness" means in regards to natural selection.
the organisms ability to survive and reproduce
The diagrams below show the skeletons of two different animal species. How does comparing the skeletons of these animals provide support for the scientific theory of evolution?
A. It provides information about the organisms' habitats.
B. It shows possible common ancestry between organisms.
C. It provides information to determine the organisms' ages.
D. It shows possible chromosomal similarities between organisms.
B.
The North American cactus and African Euphorbia (plant) are species that have evolved similar structural adaptations to conserve water and survive in a hot, dry, desert environment. They appear similar in appearance, but are not related. What type of evolution are these species demonstrating?
A. Coevolution
B. Divergent
C. Convergent
D. Mutualism
C.
Name three characteristics that are used when classifying organisms.
cell type, ability to make their own food (or not), multicellular or unicellular (number of cells)
Female cardinals choose mates by the brightest red color of male cardinal feathers. What mechanism of evolution is this?
nonrandom mating
Over evolutionary time, many cave-dwelling organisms have lost their eyes and whales have lost their hind limbs. How can natural selection account for these losses?
A. Natural selection accounts for these losses because if you don’t use it, you lose it.
B. The ancestors of these organisms experience harmful mutations that forced them to new habitats that these species had not previously used.
C. Under particular circumstances that persisted for long periods of time, each of these structures did not benefit the organism in their environment.
D. These organisms did not have the proper nutrition leading to disease.
C.
What does this picture tell us about these organisms? Why?
They share a common ancestor because their development is similar.
It has been observed that organisms on islands are different from, but closely related to, similar forms found on the nearest continent. This is taken as evidence that
A. Island species and mainland species descended from common ancestors
B. Common environments are inhabited by the same organisms
C. Island species have the same mutations as the mainland species
D. The island species and mainland species are converging
A.
Which types of organisms developed first due to the early environmental conditions on Earth?
A. prokaryotic and aerobic
B. prokaryotic and anaerobic
C. eukaryotic and aerobic
D. eukaryotic and anaerobic
B.
A tornado wipes out half the community of grasshoppers. What mechanism of evolution is this?
genetic drift
You are studying with one of your fellow classmates and they state, "The giraffe stretched its neck while reaching for higher leaves resulting in its offspring with inherited longer necks." Which statement is most likely to be helpful in correcting this student's misconception?
A. Characteristics obtained during an organism's life are generally not passed onto the offspring.
B. Mutations can result in the appearance of new traits
C. If giraffes did not have to compete with each other, longer necks would not have been passed onto the next generation
D. The offspring with long necks will reproduce offspring with longer necks
D.
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?
A. Amino acids spontaneously form from molecules in the atmosphere today.
B. Organic molecules are present today in extremely high concentrations.
C. The process of synthesizing organic molecules from a mixture of gases has been successfully modeled in the laboratory.
D. No other alternative hypotheses have been introduced.
C.
What is the endosymbiotic theory?
prokaryotic cells were engulfed by larger cells to create eukaryotic cells
