Sudan changes to deep orange or red in the presence of lipids. Sudan in not soluble in water lipids will absorb sudan's particle that will cause the change in color. Lipids will form distinct fat layer in the solution. This can be done during experiment where a macromolecule is unknown. Application of this experiment applies in health such as during confirmation of excessive fat in stool. The affinity of this dye to the lipids is high and alcoholic solutions of sudan dye can also be used.
Answer:
High Temperature, X-rays, Radiation, Some Chemicals
Explanation:
In general, mutations happen due to some error in the DNA duplication process, however, there are certain factors in the environment that can increase the incidence rate of these genetic errors. Excessive exposure to x-rays, substances present in smoke, ultraviolet light, excessive temperature, nitrous acid and some dyes present in food, for example, can favor the appearance of mutations. In general, we can say that mutations can be caused by high temperature, X-rays, radiation, some chemicals.
Lakes are a famous source of freshwater, and always have freshwater. But humans influence that and cause some bodies of water to become contaminated. Hope my answer was useful.
Carbon forms covalent bonds; the most usual kind of bond formed by carbon is a covalent bond. In the majority of situations, carbon shares electrons with other atoms because of the presence of four valence electrons.
As carbon has four valence electrons in its outermost shell, and as each covalent bond needs a donation of one electron to form the bond, carbon tends to make exactly the four bonds and is only stable if all four of these bonds are utilized.
