Answer:
The flow of heat from Earth's interior to the surface is estimated at 47±2 terawatts (TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of Earth.
Answer: Options A, B, C and D are correct.
Explanation: They can trigger the activity of histone acetyltransferases.
These RNAs functions by binding to histone-modifying complexes, to DNA binding proteins (including transcription factors), and even to RNA polymerase II.
They can silence genes by promoting the formation of euchromatin by arranging hetero- or euchromatic regions into close proximity may stabilize these domains or it may control the spreading of post-translational modifications (PTMs) to nearest chromatin.
They are actively involved in X chromosome inactivation.
They can regulate the translation and stability of mRNAs.
In Eukaryotic cells RNA transcription is a closely regulated process. Transcription of a lncRNA may regulate the transcription of nearby mRNA genes, either positively (maintaining active chromatin structure) or negatively (for example, colliding polymerases). In these cases, the RNA product may have no importance at all, or it could have an additional function.
Krebs cycle releases energy in the form of FADH_2 and NaDH
- Krebs cycle also known as Citric acid cycle
- As it was invented by Sir Hans Krebs So its known as Krebs cycle .
Carbon Dioxide (or CO2) is produced by the lungs I think because when you inhale, you breathe in oxygen, then you exhale the carbon dioxide in the lungs. That's actually 3 and 4. As for number 2, I want to say either the alvioli or however that's spelled but technically, the entire body uses oxygen so I'm not sure.
