I found this on the web: In biochemistry, chemosynthesis is the biological conversion of one or more carbon molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic (e.g. hydrogen gas, hydrogen sulfide) or methane as a source of energy, rather than sunlight, as in photosynthesis
hope this helps u out
Answer: 30-40%
Explanation:
The estimated figure is that spontaneous abortion occurs in approximately 1 in 4 recognized pregnancies, with 85% of those occurring in the first trimester (weeks 1 to 12). A 'late' miscarriage, which is much less common, can occur between weeks 13 and 24 of pregnancy.
Where a miscarriage usually occurs in the first 3 months of pregnancy, before 12 weeks of gestation. A small fraction of pregnancy losses, which occurs in less than 1% of pregnancies, are called fetal deaths, since they occur after 20 weeks of gestation.

Answer:
Tetracycline was discovered in the 1940s and is effective against both gram-positive and gram-negative bacteria. Tetracycline is an antibiotic which kills the bacteria by inhibiting the synthesis of protein.
Tetracycline act by inhibiting the process of translation by preventing the binding of aminoacyl-charged tRNA to the A site of the ribosome.
Since the aminoacyl charged tRNA does not bind the A site therefore the process of translation is inhibited.
