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.
Fossil leaves discovered by splitting bedding planes may reveal two fossils from a single specimen. The side with more organic material is called a compression. The thin carbon layer on a plant compression is known as a phytoleim (Cleal & Thomas, 2009, p. 4).ake deposits are the most common environment in which leaf and insect fossils form. Insects and leaves become trapped in sediments. As the sediments accumulate the insects and leaves may decompose leaving behind imprints.
