There are different causes to error in measurement, most common are instrument precision and misreading the measurements. Some cases are from the experimenter judging to what they want rather than the reading itself.(no offense)
But... measurements are never accurate anyway, they're all estimations.
There are four nitrogenous bases that makes DNA. These are A, T, G and C. If a DNA strand has eight pairs of nitrogenous bases, the eight bases can be
1. AA GG TT CC
2. GC GG AT CG
3. AT TA GG GC
4. GA AG GC GG
Like this, there can be 65,536 different sequences with ATCG.
Since we have 4 nitrogenous bases, pairing will make 4 X 4 = 16 combinations. If we have to make 8 pairs of bases, the number of possible sequences would be 4 to the power 8.
Answer: THERE WILL BE 65,536 DIFFERENT SEQUENCES OF 8 BASES.
Ovalbumin is the component of egg white which is responsible for foam formation.
Ovalbumin is the main protein component of the egg white and it is responsible for creating the foam structure when the egg whites are beaten. The physical stress caused by beating the egg white, causes the protein ovalbumin to denature and unfold. This denaturation, along with the mixing of air in the egg white, causes the formation of foam.
Real Depth is actual distance of an object beneath the surface, as would be measured by submerging a perfect ruler along with it. Apparent depth in a medium is the depth of an object in a denser medium as seen from the rarer medium. Its value is smaller than the real depth.
This process is called bioremediation,
