Every glucose molecule contains six atoms of carbon. One of those is grouped with one atom each of oxygen and hydrogen to form an aldehyde group, making glucose an aldohexose.
Answer:
<u><em>There are two chromatids in one duplicated chromosome.</em></u>
Explanation:
Before any cell undergoes the process of cell division, the chromosomes of the cell duplicate themselves. This results in the formation of two chromatids which are known as the sister chromatids. The chromatids are joined together from the centre at a position called the centromere. The chromatids contain the same kind of DNA in them. Chromatids are often confused with homologous chromosomes. They are not homologous chromosomes, they are the copy of a chromosome.
Well, Basalt is not a sedimentary rock,quartz is not a sedimentary rock, and slate is not a sedimentary rock, so that leaves you with your answer.
Glad I could help. ;)
<u>Answer:
</u>
"An oxygen-rich environment would cause a mass extinction of prokaryotes." Supports current scientific theories of how life might have originated on Earth.
<u>Explanation:
</u>
The reacting power of oxygen increases rigorously in an oxygen- rich environment, which leads to huge fire ignition even with the slightest spark which is generally non hazardous at all. Many prokaryotic organisms do not need oxygen as they perform anaerobic respiration. Oxygen is dangerous for some prokaryotes.
There were some prokaryotic organisms who were giving out oxygen as waste. Such excess amount of oxygen was hazardous for the environment and hence mass extinction was required to keep a check on the excess amount of oxygen being released.
