    WORTH 20 POINTS!!! Pablo and Johanna have to do a year long study for their biology

    course. After some discuss? Pablo and Johanna have to do a year long study for their biology course. After some discussion, they decide to try comparing their dogs and diet that they feed them. Each has a dog from the pound, and both dogs are less than one year old. Pablo feeds his shepherd mix dog a special diet of wet and dry foods from the local vet, while Johanna uses generic dry kibble from the supermarket for her bulldog. They want to see which diet results in bigger, healthier, faster-growing dogs.

    The independent variable in this study will be _________
    a. the age of the dogs
    b. the sex of the dogs
    c. the type of food the dogs receive
    d. how much the dogs grow
    e. the breed of the dogs

    According to the information given, one dependent variable in this study will be _____
    a. the age of the dogs
    b. the sex of the dogs
    c. the type of food the dogs receive
    d. how much the dogs grow
    e. the breed of the dogs

    when they write up their initial proposal, the instructor will probably ____
    a. give them an A for thoroughness and allow them to proceed with the experiment
    b. tell them that they need at least 100 dogs to do the study
    c. tell them that the proposal is impossible and that such a study cannot be done at all
    d. give them an F and tell them to start over -- it would take many years to do such a study
    e. tell them they have serious problems with proposal, but it is possible to fix

    the reason the instructor gives them will include the fact that they have too many ____
    a. variable that they didn't control and not enough replicates
    b. replicates and not enough variables
    c. controlled variables and not enough uncontrolled variables
    d. dependent variables and not enough independent variables
    e. independent variables and not enough dependent variables
