Answer:
Primary Succession
Explanation:
Primary Succession is a barren area exposed by a retreating glacier
Answer: Bacteria lack a mechanism for splicing out introns
Explanation:
Factor VII gene is 186k nucleotides long while the protein is 2332 amino acids long. <u>This lenght discrepancy is due to introns interrupting gene</u>, because the cell first transcribes the entire gene and then cuts introns out of the transcript. At the end, it splices the remaining pieces. Prokaryotes don't perform splicing so it can not edit out introns from the primary mRNA transcript. To produce an eukaryote gene in prokaryotes it is necessary to use a reverse transcriptase to get a cDNA sequence without the introns, and then insert that into a bacterial genome.
Like any other bird, but only at the waterside.
Answer:
Thats the cell membrane, its lets things in and out of the cell for energy and whatnot
Explanation:
cellular respiration and that stuff
A group of similar cells that perform a single function is called a tissue.
