Answer:
The amount of organic matter in mineral (sand, loam or clay) soils ranges from very low being 1% by weight, to average being 2 to 4%, and high being greater than 5%. There are also “muck” or organic or peat based soils that are 30 to 40% organic matter. The general consensus is the more soil organic matter the better. approximately 45%
Soil Composition
The basic components of soil are minerals, organic matter, water and air. The typical soil consists of approximately 45% mineral, 5% organic matter, 20-30% water, and 20-30% air. These percentages are only generalizations at best.

Explanation:
The Fluid Mosaic Model states that membranes are composed of a Phospholipid Bilayer with various protein molecules floating around within it. The 'Fluid' part represents how some parts of the membrane can move around freely, if they are not attached to other parts of the cell.
The correct answer is 50.
Proteins are complex biomolecules made out of amino-acids bound together with peptide bonds. They can be comprised out of thousands of several polypeptide chains with thousands of amino-acids organised in complex structures. But, some of them can contain only around 50 amino-acid and still posses all of the complex traits of an protein.
Some polypeptides contain only 3 amino-acids, but technically they are not classified as proteins due to a big functional and structural differences between a simple polypeptide chain and a protein. Proteins are made out polypeptide chains, but this is only the primary structure of an protein. the polypeptide chains in a protein are organized into complex 3D structures that give them novel traits and complexity as compared to plain polypeptide chains.
