  • 2. 

    An infection results from 

    • A virus or a bacteria

    • A broken bone or a twisted ankle

    • Inflammation or swelling

    • A compromised immune system or cold weather

    Correct Answer
    A. A virus or a bacteria
    Explanation
    An infection occurs when a virus or bacteria enters the body and starts to multiply, causing harm and triggering an immune response. These microorganisms can invade various parts of the body, leading to symptoms such as fever, pain, and inflammation. Infections can be transmitted through direct contact, airborne particles, or contaminated surfaces. It is important to identify the specific virus or bacteria causing the infection in order to determine the most effective treatment.

    Antibiotics

    • Should be used whenever an organism is ill

    • Are poisonous to all living organisms

    • Attack bacteria

    • Act against evolutionary forces

    Correct Answer
    A. Attack bacteria
    Explanation
    Antibiotics are medications that are specifically designed to attack bacteria. They work by targeting the bacteria's cell walls or interfering with their cellular processes, ultimately killing or inhibiting their growth. Antibiotics are not effective against viruses or other types of microorganisms, as they are specifically tailored to target bacteria. Therefore, the statement "attack bacteria" accurately describes the action of antibiotics.

    The term "super bug" refers to a(n)

    • Antibiotic resistant bacteria

    • Highly evolved insect

    • Biologically beneficial microorganism

    • Highly evolved microorganism

    Correct Answer
    A. Antibiotic resistant bacteria
    Explanation
    The term "super bug" refers to antibiotic resistant bacteria. Super bugs are strains of bacteria that have developed resistance to multiple types of antibiotics, making them difficult to treat. This resistance is usually acquired through genetic mutations or the acquisition of resistance genes from other bacteria. Super bugs are a significant public health concern as they can cause infections that are difficult to treat and can spread easily in healthcare settings.

    A virus infects a living organism by messing with its 

    • Structure

    • DNA

    • Friends and relatives

    • Cytoplasm

    Correct Answer
    A. DNA
    Explanation
    A virus infects a living organism by interfering with its DNA. Viruses are microscopic infectious agents that invade cells and use the host's cellular machinery to replicate. They insert their genetic material, which is usually DNA or RNA, into the host cell's DNA. This disrupts the normal functioning of the host cell and allows the virus to take control and reproduce. By manipulating the host cell's DNA, the virus can hijack the cell's resources and cause various diseases and infections.

    What is an example of directional selection?

    • The average beak size of finches remains the same over generations.

    • Darker peppered moths becoming more common in polluted areas.

    • Both large and small seeds are favored in a bird population.

    • A population of rabbits maintaining a stable fur color.

    Correct Answer
    A. Darker peppered moths becoming more common in polluted areas.
    Explanation
    Directional selection occurs when environmental changes favor individuals at one extreme of a trait spectrum, leading to a shift in the population's traits toward that extreme. A well-known example is the case of peppered moths during the Industrial Revolution in England. As pollution darkened the trees with soot, darker-colored moths, which were better camouflaged, had a survival advantage over lighter-colored moths. This led to an increase in the population of darker moths, illustrating how directional selection can drive evolutionary change in response to environmental shifts.

    What is the most highly-evolved species on the planet?

    • There isn't one. All species are evolving.

    • Evolution has not finished working. The most highly-evolved species is yet to come.

    • Homo sapiens or human beings

    • Orca whales

    Correct Answer
    A. There isn't one. All species are evolving.
    Explanation
    The correct answer is that there isn't one highly-evolved species on the planet because all species are evolving. Evolution is an ongoing process, and no species can be considered as the most highly-evolved because there is always room for further development and adaptation. This answer highlights the continuous nature of evolution and emphasizes that no species has reached a final or ultimate state of evolution.

    Evolution is

    • The gradual progression of forms into more advanced versions over millions of years

    • Natural selection acting on a population that has variation

    • An idea that is unsupported by observation

    • Guided by the more advanced individuals in a group

    Correct Answer
    A. Natural selection acting on a population that has variation
    Explanation
    Evolution is the process of change in living organisms over time. It occurs through natural selection, where individuals with advantageous traits are more likely to survive and reproduce, leading to the propagation of those traits in the population. This process relies on the presence of variation within a population, as it allows for the selection of traits that are best suited for the environment. Therefore, the correct answer is "natural selection acting on a population that has variation."

    Evolution can be observed every year when

    • Bacteria evolve into amphibians in wet ecosystems

    • New moth species evolve in urban centers

    • Animal species mutate at radioactive sites

    • Flu viruses evolve

    Correct Answer
    A. Flu viruses evolve
    Explanation
    Flu viruses evolve every year because they have a high mutation rate and can quickly adapt to new environments. This is why new strains of the flu virus emerge regularly, requiring the development of new vaccines to combat them.

    If antibiotics are used casually, it can lead to

    • Improved health outcomes

    • The extinction of infectious bacteria, leaving only beneficial bacteria

    • The extinction of all bacteria

    • The evolution of a super bug

    Correct Answer
    A. The evolution of a super bug
    Explanation
    If antibiotics are used casually, it can lead to the evolution of a super bug. Casual use of antibiotics can create an environment where bacteria are exposed to low doses of antibiotics, which can promote the development of resistance in bacteria. Over time, this can lead to the emergence of superbugs that are resistant to multiple antibiotics, making them difficult to treat and control. This can have serious consequences for public health as infections caused by these superbugs become more difficult to manage.
