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.
And, with metasomatism we have rock-altering fluid involved. This process is seen in the creation of anthracite coal. The parent rock, bituminous coal, is formed from the compaction of dead plant matter, usually in a wet, swampy environment.
