Explanation:
RNA splicing was first discovered in 1970s in viruses and subsequently in eukaryotes. Not long after, scientists discovered alternative patterns of pre-mRNA splicing that produced different mature mRNAs containing various combinations of exons from a single precursor mRNA. The first example of alternative splicing of a cellular gene in eukaryotes was identified in the IgM gene, a member of the immunoglobulin superfamily. Alternative splicing (AS) therefore is a process by which exons or portions of exons or noncoding regions within a pre-mRNA transcript are differentially joined or skipped, resulting in multiple protein isoforms being encoded by a single gene. This mechanism increases the informational diversity and functional capacity of a gene during post-transcriptional processing and provides an opportunity for gene regulation
Answer:
The answer is D) Fossil Evidence
Explanation:
Looking at creatures thousands of years old entrapped in fossils gives you the most solid evidence that things have changed greatly over time. Hope this helps :)
The correct answer is fermentation.
The production of energy needs oxygen. The electron transport chain, where the most of ATP is produced, needs a huge input of oxygen. However, there are various species, which have produced methods to continue the metabolism in the absence of oxygen, or can move from aerobic to anaerobic cell respiration when oxygen is enough.
At the time of cellular respiration, some of the living species utilize an organic substance as the eventual electron acceptor. The procedures that utilize an organic molecule to reproduce NAD+ from NADH are in a combination known as fermentation.
In comparison, some of the living species utilize an inorganic substance as an ultimate electron acceptor. Both the procedures are known as anaerobic cellular respiration, where the species are obtaining energy for their application in the absence of oxygen.
