<span>I think you might be asking about the 3 different osmotic conditions a cell might find itself in. Isotonic is the normal cell environment where water moves in and out of the cell freely and equally in both directions. It is in osmotic equilibrium so to speak. The concentration of water and solutes is equal on both sides of the cello membrane. In a hypotonic solution the cell will gain water and swell up -...</span>
Answer & Explanation:
After a complimentary DNA chain is generated as messenger RNA (mRNA), Sequence of nuclotides in a mRNA directs the addition of a specific sequence of amino acids to form the protein. This usually occur on ribosome.
The polypeptide chain now increases in length by covalent attachment of successive amino acids units, each carried to the ribosome and correctly positioned by its transfer RNA (tRNA). The completion of the polypeptide chain is signalled by a termination codon present in the mRNA.
Mass extinction refers to the procedure in which a huge number of species gets extinct suddenly.
The following are the correct matches of the events taken place in the mentioned time period:
1. Cretaceous-Tertiary: The mass extinction of dinosaurs took place.
2. End-Triassic: Possibly resulting due to massive rifting of the surface of the Earth.
3. Permian-Triassic: It is considered the worst mass extinction in the history of the Earth.
4. Late Devonian: It is possibly a result of the growth of forest on the land surface of the Earth.
5. Ordovician-Silurian: The earliest mass extinction took place at this time.
