Following statements are regarding thyroid hormone biosynthesis?
I. The basolateral membranes of thyrocytes facing the capillaries contain a antiporter that transports two Na+ ions and one I– ion into the cell with each cycle, against the electrochemical gradient for I–.
II. Na+/I– symporter (NIS) is capable of producing intracellular I– concentrations that are 20–40 times as great as the concentration in plasma.
III. TSH induces both NIS expression and the retention of NIS in the basolateral membrane, where it can mediate sustained iodide uptake.

Chickadees were given an opportunity to store seeds in 72 possible storage sites consisting of holes drilled in small trees that had been placed in an aviary. Typically, the seeds were placed in only 4 or 5 storage sites. The chickadees were then removed from the aviary, the seeds removed from the storage sites, and each hole covered. A day later, the chickadees were returned to the aviary and they spent nearly 5 times as long pulling at the covers on storage sites than at the covers on sites where they had not stored food. This experiment indicates that chickadees
