i have 6 questions, each with an answer. i would appreciate if you review the questions check my answers. tank you very much tutors.
variables and graphing assessment practice
Ethylene is a plant hormone that causes the fruit to mature. The data below concerns the amount of time it takes for fruit to mature form the time of the first application of ethylene by spraying a field of trees.

1. What is the problem?
my answer: Someone wants to find the amount of time it takes for the Wine Sap Apples, Golden Apples, and Gala Apples to mature.
2. Write a hypothesis for this experiment.
my answer: If you use more amount of ethylene on fruits, then they will mature faster.
3. What is the independent variable?
my answer: The amount of ethylene given or added to the fruits in mL
4. What is the dependent variable?
my answer: The amount of time it takes for the fruit to mature
5. What is the control group?
my answer: The type of fruit used for each trials
6. Name 3 constants.
my answer: The amount of water given to the trees, exposure of light to the trees, type of soil the trees are in
tank you tutors for reviewing and checking my answer, much appreciated. feel free to give suggestions.
What is the problem? To relate amount of ethylene to ripening time.
What is the control group? There are no independent control groups, each of those fruits should have been given ripening time with no ethylene
otherwise, looks ok.
tank you bobpursley, but i changed the problem to: To relate amount of ethylene to the maturity of the fruits
and the control group to: No control group, but each of these fruits should have been given marurity stage with no ethylene
1. Your answer to the first question is correct. The problem is to find the amount of time it takes for the Wine Sap Apples, Golden Apples, and Gala Apples to mature using different amounts of ethylene.
2. Your answer to the second question is appropriate. Your hypothesis states that if you use a larger amount of ethylene on the fruits, they will mature faster.
3. Your answer to the third question is accurate. The independent variable in this experiment is the amount of ethylene given or added to the fruits, measured in mL.
4. Your response to the fourth question is correct. The dependent variable in this case is the amount of time it takes for the fruit to mature.
5. Your answer to the fifth question is partially correct. The control group in this experiment is not the type of fruit used, but rather the group of fruits that does not receive any ethylene treatment. Therefore, the control group is the group of fruits where no ethylene is added.
6. Your answer to the sixth question is mostly correct. The three constants in this experiment are the amount of water given to the trees, exposure of light to the trees, and the type of soil the trees are in.
Overall, your answers are quite well done. Keep in mind that the control group should reflect the absence of the independent variable (ethylene treatment in this case) to serve as a baseline for comparison.
