he researchers bought samples of whale meat-all labeled simply as kujira, the generic Japanese term for whale meat-from markets in Japan and sequenced DNA from these samples. They compared their data with sequences from known whale species. Because subspecies of whales from different populations differ genetically, the researchers were able to analyze the genetic variation in their samples and learn the location from which the whales were likely captured. These results would indicate if illegal whale meat was being sold.

    First, let's complete the question by adding the missing piece of information

    Match each statment as question, observation, hypothesis, prediction, or test

    1) Whales are being harvested illegally and their meat sold in markets in Japan

    2) Where is the whale meat being solid in Japanese markets coming from?

    3) If whale-s are being illegally harvested, reported whale captures will be far lower tahn the number of captures predicted by genetic analyses of whale meat in markets

    4) The availability of whale meat in Japanese markets exceds that expected from the reported legal captures of whales

    5) Scientists subject whale meat to genetci analysis to determine its likely capture location and to extimate whale captures at that location

    Answer:

    Question: - where is the whale meat being sold in Japanese markets coming from?

    Observation: - The availability of whale meat in Japanese markets exceds that expected from the reported legal captures of whales.

    Hypothesis: - If whales are being illegally harvested, reported whale captures will be far lower than the number of captures predicted by genetic analyses of whale meat in markets.

    Prediction: - Whales are being harvested illegally and their meat sold in markets in Japan.

    Test: - Scientists subject whale meat to genetic analysis to determine its likely capture location and to estimate whale captures at that location.

    Explanation:

    A Scientific method is a basic problem solving step in biology, chemistry and physics.

    The scientific method entails:

    1) Observation: Data you gathered in thr course of an experiment

    2) Question: what you desire to know or have answer to

    3) Hypothesis: a possible explanation which can be tested to prove if it is going to be correct or if we need to propose a new hypothesis.

    4) Prediction (is dependent on the Hypothesis) : the expected outcome

    5) Test: to undergo an experiment on the variable or data given.
