    A __________ is a well-tested explanation for a broad set of observations.

    Explanation
    A theory is a well-tested explanation for a broad set of observations. The term "theory" refers to a comprehensive framework that has been developed through rigorous testing and analysis of various observations and data. It provides a systematic explanation for a wide range of phenomena or events in a particular field of study. Theories are supported by empirical evidence and are constantly refined and updated as new information becomes available. They serve as a foundation for further research and understanding in a given area of knowledge.

    Since the supply of fossil fuels are unlimited there is no need to find alternative fuel sources such as biodiesel, which is obtained from soybean plants. 

    • False, fossil fuels are not unlimited

    • True, we will never run out of petroleum

    Correct Answer
    A. False, fossil fuels are not unlimited
    Explanation
    The given answer is "False, fossil fuels are not unlimited." This means that the statement "Since the supply of fossil fuels are unlimited there is no need to find alternative fuel sources such as biodiesel, which is obtained from soybean plants" is incorrect. The explanation for this is that fossil fuels are not unlimited. Fossil fuels are formed over millions of years from the remains of plants and animals, and they are being consumed at a much faster rate than they are being replenished. As a result, there is a finite supply of fossil fuels, and eventually, they will run out. Therefore, it is important to find alternative fuel sources like biodiesel to reduce our reliance on fossil fuels.

    The variable that that you change during an experiment is the ____________ variable.

    Correct Answer
    manipulated
    Explanation
    The manipulated variable is the variable that is intentionally changed or manipulated by the experimenter during an experiment. It is the variable that is under the control of the experimenter and is used to test its effect on the dependent variable. By manipulating this variable, the experimenter can observe and measure the resulting changes in the dependent variable, allowing them to draw conclusions and make inferences about cause and effect relationships.

    When you use your senses to obtain information, you make a(n)?

    • Hypothesis

    • Scientific Law

    • Observation

    • Judgement

    Correct Answer
    A. Observation
    Explanation
    When you use your senses to obtain information, you make an observation. Observations involve gathering data and information through the use of our senses, such as seeing, hearing, smelling, tasting, and touching. It is the first step in the scientific method and helps in forming hypotheses and making judgments based on the collected data.

    Farmers learned to conserve water by placing genes from a jellyfish into a potato plant 

    • True, the plant glows when it needs water

    • False jellyfish couldn't live in a potato field

    Correct Answer
    A. True, the plant glows when it needs water
    Explanation
    The given correct answer is true, the plant glows when it needs water. This is because farmers have genetically modified the potato plant by inserting genes from a jellyfish. These genes allow the plant to produce a fluorescent protein that glows when it is under stress or in need of water. This helps the farmers to easily identify which plants require watering, enabling them to conserve water by only irrigating the plants that actually need it.
