Parathyroid Hormone. Parathyroid hormone is the most important endocrine regulator of calcium and phosphorus concentration in extracellular fluid. This hormone is secreted from cells of the parathyroid glands and finds its major target cells in bone and kidney.Another hormone, parathyroid hormone-related protein, binds to the same receptor as parathyroid hormone and has major effects on development. This effect is mediated by stimulating tubular reabsorption of calcium. 2  Another effect of parathyroid hormone on the kidney is to stimulate loss of phosphate ions in urine.
Currently the highest known tree in the world is coast redwood (Sequoia sempervirens (D. Don) Endl.) in United States, California. It is 115.61 m high. But there are credible statements about taller trees in recent past.

They're answer was Redwood National and State Parks. Which is in California. I wonder if the people who are in charge of this reward point challenge if he was from another country and had looked up the answer on Google to get it for the question they came up with for their trivia challenge.
