Annette has her thyroid gland removed because of a malignant tumor. She takes synthetic thyroid hormone to replace the thyroxine that her thyroid gland would have produced, but she is worried about her blood calcium level since she has lost her source of calcitonin. Does she need to worry about this problem
Answer:
She doesn't need to worry if her parathyroid glands are working.
Explanation:
Although Annette has to worry about the impacts of thyroid gland removal and synthetic thyroid hormone intake, the calcium levels in her body need not be a concern as long as her parathyroid glands are functioning normally.
This is because the parathyroid glands are responsible for regulating calcium levels in the blood, through the production of parathyroid hormones or parathormone.

None of the oxygen from water was found in glucose.
What should the scientist do to best gain scientific understanding of this topic?
a. Analyze the results, and change the experimental methods to retest the hypotheses in a different way.
b. Discard the faulty results that do not support the original hypothesis, and repeat the experiment using the same methods.
c. Analyze the procedural errors that took place in the experiment, and summarize these in a conclusion statement.
d. Repeat the experiment and adjust new data to support the original hypothesis.
The scientist Discard the faulty results that do not support the original hypothesis, and repeat the experiment using the same methods; option B.
What is an experiment?An experiment is a research or test conducted in order to prove or disprove a hypothesis.
