Answers
Answer
You think people with hypothyroidism will start to produce more thyroid hormone if given a new drug called Drug M. You take 3 different groups of people with hypothyroidism. You give one group 4 pills of Drug M everyday, you give another group 2 pills of Drug M each day, and you give another group 0 pills. You measure how much thyroid hormone is in the patients' blood over the next month.

1. The variable being tested is the pH level (acidity) of the environment in which the bacteria are grown.
2. The best conclusion to draw from this experiment is:
**c. High acidity is harmful to this type of bacteria.**
This conclusion is supported by the observation that as the pH decreases (becoming more acidic), the number of colonies decreases significantly, with no growth at pH 4.

3. The variable being tested is the dosage of Drug M.
4. Test for the presence of thyroid hormone in the blood.

Yes, the answers provided are correct given the context of the questions.
1. For the first question, the variable being tested in the bacteria experiment was indeed the pH level, which affects bacterial growth.
2. For the second question, the conclusion that high acidity is harmful to the type of bacteria was based on the observed growth patterns across different pH levels.
3. In the third question about hypothyroidism, the variable tested is correctly identified as the dosage of Drug M, as that is the independent variable being manipulated in different groups.
4. For measuring the dependent variable (the amount of thyroid hormone), the correct method is to test for the presence of thyroid hormone in the blood, as hormones typically need to be measured with specific assays rather than visible counting or measuring like physical objects.
If you have any specific concerns or if you're looking for deeper clarification or alternative interpretations, please let me know!
