Diet and Thyroid  Iodine is an important micronutrient involved in thyroxine production. Without adequate iodine present in the diet, a thyroid dysfunction called a goitre may occur.    A hypothesis is a proposed statement or a prediction that explains a phenomenon. In other words, it describes what you think will happen in an experiment and offers a starting point that requires further investigation. Page 122 of your Biology textbook states that "A hypothesis is a statement that provides one possible answer to a question, or one possible explanation for an observation." Hypotheses are based on previous knowledge or evidence and are tested in a variety of ways, including experiments and observations. Iodine is the element necessary for the synthesis of thyroxine.  In your own words, write a hypothesis about how an excess of iodine in the diet may or may not affect the amount of thyroxine produced by an individual  (think about the negative feedback loop that regulates thyroxine levels)
