The correct answer of the given question above would be option D. The option that did not occur during the Cenozoic era is the formation of the ozone layer. The ozone layer has long been there before any era since it is part of the earth's atmosphere. Hope this answer helps.
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division. There are three forms of nondisjunction: failure of a pair of homologous chromosomes to separate in meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during mitosis.[1][2][3] Nondisjunction results in daughter cells with abnormal chromosome numbers (aneuploidy).
Calvin Bridges and Thomas Hunt Morgan are credited with discovering nondisjunction in Drosophila melanogaster sex chromosomes in the spring of 1910, while working in the Zoological Laboratory of Columbia University.[4]
Answer:Transcriptional Regulation
Explanation:
Eukaryotic gene expression can be regulated during the time of transcription and RNA processing, which takes place in the nucleus of the cell and then during the time of protein translation in the cytoplasm.
Further regulation is being carried during the time of post transnational modification. The conservation of energy is very important because it saves the overall energy and space in the body.
Hence, the most important point for the regulation would be transcriptional regulation.
3: Geothermal energy
4: An earthquake is the result of a sudden release of stored energy in the Earth's crust that creates seismic waves. ... An earthquake is caused by tectonic plates getting stuck and putting a strain on the ground. ... When the failure at the fault plane results in a violent displacement

Answer:
A sequence of three nitrogenous bases in a messenger-rna molecule is known as <em><u>Codon</u></em>
Explanation:
Codon is a triplet of three nitrogenous bases present in mRNA. It can be any three from uracil, adenine, guanine or cytosine. They are arranged in specific order and code for specific amino acids.
