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.
Why will plants die if soil becomes compacted or saturated? When soil becomes compacted the pore-space between the soil particles is reduced or removed entirely. Smaller (or no) pore spaces means that oxygen levels in the soil are decrâ¦eased - almost 80% of a plants oxygen is obtained through exchange in the roots. Smaller (or no) pore spaces in the soil results in saturated or waterlogged soil, this in turn exacerbates the low oxygen levels by forcing even more air from the soil.
