Answer: Minerals
Explanation: The body decomposes and after about 40 to 50 years bones are mostly brittle and dry with no traces of flesh. After thousands of years bones also disintegrate (decay) leaving brittle mineral frame. The life of bones is determined by the soil type its buried in, nuetral soils takes longer then acidic soil condition.
In this case osteocytes(bone cells) are the first to decompose followed by the cartilage and bone marrow, leaving behind mineral traces that scientist can study after thousand years.
They are capable of renewing and dividing (multiplying) themselves for long periods of time, they are unspecialized, and they can give rise to other specialized cell types. Hope this helps!! :)
The limitation is that she can't test is on humans for ethical reasons. In order to test this, theoretically, she would need to ask some women to use this cosmetic and compare their fetuses to the fetuses of women who didn't. But this is not likely to be approved by the ethical committee, as causing damage to a fetus is not ethical.
Two-third fraction of the carbon dioxide molecules released is generated during the citric acid cycle.
Explanation:
Aerobic respiration results in energy production as well as releases the waste products of carbon dioxide plus water.
Pyruvate oxidation during aerobic respiration leads to the production of carbon dioxide and pyruvate is converted into a two-carbon molecule aligned with acetyl CoA.
This compound then proceed to the citric acid cycle, oxidize, and results in the production of two carbon dioxide molecules along with one GTP or an ATP, 3 NADH, and 1 FADH molecule.
The citric acid cycle or the tricarboxylic cycle is a set of cyclic biochemical reactions taking place in aerobic organisms to oxidize the acetate (acetyl carbon molecules of the acetyl CoA) from proteins, carbohydrates, and fats into carbon dioxide and release energy.
