This gland produces hormones that regulate metabolism, including body weight and heart rate. When the thyroid is not functioning properly, it can lead to either too much or too little of these hormones. When a pregnant woman has an untreated underactive thyroid, also known as hypothyroidism, there is a risk of decreased intelligence in the child.

If the mother receives treatment for her hypothyroidism, there will not be any negative impact on the child's intelligence. Using the information provided, answer the following questions.
