Treatment of hypothyroidism with levothyroxine is effective, but starting doses vary. There are two strategies for initiating levothyroxine in healthy adults younger than 65 years: low-dose (50 mcg) and full-dose (1.6 to 1.7 mcg per kg).
The only good example of this is chalk, which is made from the compacted shells of tiny marine organisms called diatoms. Other than that, animal and plant remains do not tend â¦to form rocks, although the hard parts may form fossils.
Peat moss is formed when sphagnum moss builds up and becomes compacted in bogs, which are shallow, wet environments. It can take thousands of years for a mature peat bog to form. Peat bogs are typically found in northern latitudes, with Canada housing approximately 25 percent of them, according to Cornell University.
