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.

Answer: </u></h2>
<u>Erosion:</u> is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.Erosion is the opposite of deposition, the geological process in which earthen materials are deposited, or built up, on a landform.
Most erosion is performed by liquid water, wind, or ice . Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment.
<u>Public domains:</u>VegetationThe simplest and most natural way toprevent erosion is through planting vegetation. Plants establish root systems, which stabilizes soiland prevents soil erosion. Geotextiles: Using geotextiles is an effective method because it also stabilizes soi

People placing sandbags along the shore of a river:</u>
The use of sandbags is a simple, but effective way to prevent or reduce floodwater damage. Properly filled and placed sandbags can act as a barrier to divert moving water around, instead of through, buildings. ... Tied sandbags are generally easier to handle and stockpile.
FloodSax Sandless Sandbags are reusable only in fresh water.FloodSaxreusable sandbags can be used a second or third time, depending on how clean the liquid it has absorbed. Click here to purchase FloodSax reusable sandless sandbags now.
Answer:
hypothesis is an idea or explanation that then test through study and experimentation
Proteins attract water and hold it within blood vessels, preventing it from freely flowing into the spaces between the cells. This is an example of how protein is used for maintaining fluid and electrolyte balance.
<h3>What is Protein?</h3>
- Large biomolecules and macromolecules known as proteins are made up of one or more extended chains of amino acid residues.
- Among the many tasks that proteins carry out in living things include catalyzing metabolic processes, replicating DNA, reacting to stimuli, giving cells and organisms structure, and moving molecules from one place to another.
- The primary way that proteins differ from one another is in the order of their amino acids, which is determined by the nucleotide sequence of their genes and typically causes a protein to fold into a certain 3D structure that controls its activity.
<h3>What Constitutes Proteins? </h3>
- Amino acids, which are tiny chemical compounds with an alpha (central) carbon atom coupled to an amino group, a carboxyl group, a hydrogen atom, and a variable component known as a side chain, are the building blocks of proteins.
