Answer:
Prokaryotes have no cell nucleus and no membrane enclosed organelles. Prokaryotic DNA can be found in a coiled loop floating in the cytoplasm in a region called the nucleoid (meaning nucleus-like). In other words, the nucleoid is the area in a prokaryotic cell where DNA is located.
Explanation:
Through pH scale. it measures the acidity of a substance, pH is measured with a litmus paper, if the paper turns red then it is acidic.
These are the two phases involved in chromatography. The mobile phase is usually liquid and is the solvent between the two. The solvent can attract some substances that has an affinity to it, thereby separating the polar from the non polar substances. On the other hand, the stationary phase is the media or medium which is a solid substance in which the unknown sample or the solution to be analysed is passed. As the term implies , it is stationary and substances in the unknown sample that has affinity to it or to the reagents in it will not travel along the column, but stay with the stationary medium, thereby allowing a separation of the substances present in the unknown sample/solution.
Answer:
~0.0004
Explanation:
n=0.072/(56+(35.5*3))=0.072/162.5~~0.004
