About This Quiz

The Unit 1 Review Quiz assesses understanding of evolutionary mechanisms, such as natural selection and mutation, and their effects on populations. It explores concepts through questions about genetic traits, fossil analysis, and homologous structures, emphasizing critical thinking and application of evolutionary theory.

    Which mechanism of evolution causes a change in a POPULATION over time?

    • Mutation

    • Natural Selection

    • Gene Flow

    • Genetic Drift

    Correct Answer
    A. Natural Selection
    Explanation
    Natural selection is the mechanism of evolution that causes a change in a population over time. It is the process by which certain traits become more or less common in a population based on their ability to survive and reproduce. Individuals with advantageous traits are more likely to survive and pass on their genes to the next generation, while individuals with disadvantageous traits are less likely to reproduce. This leads to a gradual change in the population's genetic makeup over time, as favorable traits become more prevalent and unfavorable traits become less common.

    What can you conclude based on this drawing? - ProProfs

    What can you conclude based on this drawing?

    • Fossils in layer Q are younger than layer H

    • Fossils in layer Q are older than layer H

    • Fossils in layer J are older than layer I

    • Fills in layer P are younger than layer K

    Correct Answer
    A. Fossils in layer Q are older than layer H
    Explanation
    The fossils at the bottom will be older than the fossils at the top

    TRUE or FALSE: Homologous structures have the same function in different species.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Homologous structures are anatomical features that have a similar structure but may not necessarily have the same function. These structures are derived from a common ancestor and may have been modified over time to serve different purposes in different species. Therefore, homologous structures do not have the same function in different species, making the given answer "False" correct.

    Which mechanism of evolution causes the initial change in the traits of an INDIVIDUAL, adding genetic diversity?

    • Mutation

    • Natural Selection

    • Gene Flow

    • Genetic Drift

    Correct Answer
    A. Mutation
    Explanation
    Mutation is the correct answer because it is the mechanism of evolution that causes the initial change in the traits of an individual. Mutations are random changes in the DNA sequence, which can result in new genetic variations. These variations can then be passed on to future generations, contributing to genetic diversity within a population. Natural selection, gene flow, and genetic drift can all act on these mutations, but they do not directly cause the initial change in traits.

    What is the correct order of taxonomic groups from most general to most specific?

    • Kingdom, Phylum, Order, Class, Family, Genus, Species

    • Kingdom, Phylum, Class, Order, Family, Genus, Species

    • Species, Genus, Family, Order, Class, Phylum, Kingdom

    • Species, Family, Genus, Order, Class, Phylum, Kingdom

    Correct Answer
    A. Kingdom, Phylum, Class, Order, Family, Genus, Species
    Explanation
    The correct order of taxonomic groups from most general to most specific is Kingdom, Phylum, Class, Order, Family, Genus, Species. This order follows the hierarchical classification system used in taxonomy, where organisms are grouped based on their shared characteristics. The kingdom is the broadest category, followed by phylum, class, order, family, genus, and species, which is the most specific category.

    Why are these considered analogous structures, not homologous structures? - ProProfs

    Why are these considered analogous structures, not homologous structures?

    • They have the same structure but a different purpose

    • Even though they have the same structure, they did not have a common ancestor with that structure

    • They have completely different structures and purposes

    • They have a common ancestor with the same trait

    Correct Answer
    A. Even though they have the same structure, they did not have a common ancestor with that structure
    Explanation
    These structures are considered analogous because even though they have the same structure, they did not have a common ancestor with that structure. Homologous structures, on the other hand, are structures that have a common ancestor with the same trait. Therefore, since these structures did not evolve from a common ancestor with the same structure, they are considered analogous rather than homologous.

    These limbs provide evidence of common ancestry because they - ProProfs

    These limbs provide evidence of common ancestry because they

    • Have the same basic structure

    • Perform the same function

    • Are the same size

    • Are parts of mammals

    Correct Answer
    A. Have the same basic structure
    Explanation
    The fact that these limbs have the same basic structure suggests a common ancestry because it implies that they have evolved from a common ancestor. This similarity in structure indicates that the limbs share a common developmental pathway and genetic blueprint, which is a strong indicator of common ancestry.

    The presence of wings in bats, birds, and insects is an example of a(n): - ProProfs

    The presence of wings in bats, birds, and insects is an example of a(n):

    • Homologous structure

    • Vestigial structure

    • Karyotype structure

    • Analogous structure

    Correct Answer
    A. Analogous structure
    Explanation
    This is an analogous structure because they have different structures (different ancestors), but the same function

    The graphs show the change in the population of fish over time. Some fish have spines (with spines) while others do not have spines (no spines). What is the trend you see over time in these graphs and how can natural selection make this occur? - ProProfs

    The graphs show the change in the population of fish over time. Some fish have spines (with spines) while others do not have spines (no spines). What is the trend you see over time in these graphs and how can natural selection make this occur?

    • There's the same number of fish with no spines and with spines because natural selection produces diversity

    • There's a higher number of fish with no spines because all of the fish mutated to have no spines

    • There is a higher number of fish with spines over time because the fish with spines are better able to survive and reproduce

    • There is a higher number of fish with no spines over time because the fish with no spines were better able to survive and reproduce

    Correct Answer
    A. There is a higher number of fish with no spines over time because the fish with no spines were better able to survive and reproduce
    Explanation
    Natural selection is the process by which individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to future generations. In this case, the trend observed is that there is a higher number of fish with no spines over time. This suggests that the fish without spines have a better chance of survival and reproduction, leading to an increase in their population. Therefore, natural selection favors the fish without spines, as they are better adapted to their environment and have a higher fitness.

    What is a trait that animals and fungi have in common?

    • Cell Walls made of Chitin

    • Both are autotrophs

    • Both are heterotrophs

    • Both are motile (can move around)

    Correct Answer
    A. Both are heterotrophs
    Explanation
    Both animals and fungi share the trait of being heterotrophs. This means that they obtain their nutrients by consuming organic matter from other sources. Unlike autotrophs, which can produce their own food through photosynthesis, both animals and fungi rely on external sources for their energy and nutrients. This common characteristic of being heterotrophs distinguishes them from autotrophic organisms.

    Select all of the kingdoms below that are Eukaryotes (check all that apply)

    • Animalia

    • Bacteria

    • Archaebacteria

    • Plantae

    • Fungi

    • Protista

    Correct Answer(s)
    A. Animalia
    A. Plantae
    A. Fungi
    A. Protista
    Explanation
    The correct answer includes Animalia, Plantae, Fungi, and Protista. These are all kingdoms that belong to the domain Eukaryota, which consists of organisms with eukaryotic cells. Eukaryotic cells have a true nucleus and membrane-bound organelles, distinguishing them from prokaryotic cells found in Bacteria and Archaebacteria.
