The sodium levels increase inside the cell during action potential. Opposite to resting state, depolarization is the shift of electrical charge resulting in positive charge inside the cell. Depolarization is the start of cell-to-cell communication and other necessary physiological functions of an organism.

Belonging to the large family of alcohols, propylene glycol is a chemical element widely used by the food industry thanks to its recognized emulsifying properties. It is referable to its acronym E1520. This colorless, low volatile and soluble diol is also used in many other industries. Pharmaceutical, cosmetic, aeronautic, textile industries ... Propylene glycol is involved in the composition of many polymers such as polyester. Non-toxic when inhaled, propylene glycol is used in electronic cigarette filling fluid to produce an aerosol effect comparable to that of smoke.
With respect to polypropylene glycol, each condensation of propylene glycol causes a loss of a water molecule
C3H8O2 + C3H8O2 + C3H8O2 ==> C9H20O4 + 2H2O

Answer:
Crossing over and random distribution of chromosome will lead to random assortment of new combinations of alleles on the same chromosome.
Explanation:
Crossing can be defined as the exchange of genetic material between homologous chromosomes.
Variation can occur when the sister chromatids have mixture of alleles ( paternal).
This leads to genetic diversity.
This genetic variation is the bedrock and foundation of evolution. This bring about differences in different organisms and when organism differs genetically, they will have different level of adaptability and survival instincts. The eventual result of this is survival of the fittest.
