    Climate change is controlled by a single factor.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Climate change is not controlled by a single factor. It is a complex phenomenon influenced by a variety of factors including greenhouse gas emissions, deforestation, industrial activities, and natural processes such as volcanic eruptions and solar radiation. These factors interact with each other and contribute to changes in temperature, precipitation patterns, and sea levels over time. Therefore, the statement that climate change is controlled by a single factor is false.

    The decline in American bald eagle populations was due to adult eagles consuming high concentrations of DDT that lowered calcium levels and weakened egg shells, resulting in shells that broke during incubation or hatching failures.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The explanation for the given correct answer is that the decline in American bald eagle populations was indeed caused by adult eagles consuming high concentrations of DDT. This pesticide lowered calcium levels in their bodies, leading to weakened egg shells. As a result, the shells broke during incubation or hatching, leading to failures in reproduction. This explanation highlights the impact of DDT on the bald eagle populations and the subsequent decline in their numbers.

    What factors contributed to the bald eagle population comeback?

    • Legal protection such as the Endangered Species Act.

    • The implementation of fines for interfering with protected nesting areas.

    • Banning the use of DDT in the United States.

    • Deliberate reintroduction of bald eagles.

    Correct Answer(s)
    A. Legal protection such as the Endangered Species Act.
    A. The implementation of fines for interfering with protected nesting areas.
    A. Banning the use of DDT in the United States.
    A. Deliberate reintroduction of bald eagles.
    Explanation
    The bald eagle population comeback can be attributed to a combination of factors. Legal protection provided by the Endangered Species Act helped in safeguarding the species and their habitats. The implementation of fines for interfering with protected nesting areas discouraged human interference, allowing the eagles to thrive. Banning the use of DDT in the United States was crucial as this pesticide was harmful to the eagles and their reproductive abilities. Additionally, deliberate reintroduction efforts played a significant role in boosting the bald eagle population.
