The answer is the second one (or B): thyroxine.

Explanation for each option:

  • Isthmus: This is not a hormone; it refers to a narrow piece of tissue connecting two larger parts, such as the isthmus of the thyroid gland.
  • Thyroxine: This is the correct answer. Thyroxine, also known as T4, is a thyroid hormone that contains four iodine atoms.
  • Triiodothyronine: This is another thyroid hormone, but it contains three iodine atoms, not four.
  • Pars: This term refers to a part or segment of an organ or structure, not a hormone.

Summary: The thyroid hormone with four iodine atoms is thyroxine.

A highway whose primary directions are north/south is being constructed along the west coast of a region. At one point, a bay obstructs the straight path of the road. Since the cost of a bridge is prohibitive, engineers decide to go around the bay. The figure shows a diagram of the path that they decide on and the measurements taken. If L=2 mi, what is the length of highway needed to go around the bay? The total length of the highway needed to go around the bay is about miles. (Do not round until the final answer. Then round to two decimal places as needed.)
