Answer:
In unicellular organisms, cell division is the means of reproduction; in multicellular organisms, it is the means of tissue growth and maintenance. Survival of the eukaryotes depends upon interactions between many cell types, and it is essential that a balanced distribution of types be maintained. This is achieved by the highly regulated process of cell proliferation. The growth and division of different cell populations are regulated in different ways, but the basic mechanisms are similar throughout multicellular organisms.

Explanation:
 we all want to improve air quality in our environments. especially in cities.., unfortunately, the $ you save from "going green," will now cause extra taxes,in the near future, which will defeat the purpose of saving $...from green sources adding another tax for your hard earned resources, example, when u buy a property with wooded areas, in rural towns of illinois, you are charged a green tax, plus higher property taxes to compensate electricity. 
therefore, investment in clean energy shud b divided into yearly income per year..hense, people of higher income shud b taxed mor to the rich and people who can afford it. bluecollors are always taxed more than peps
that can actually afford it..
just my thought...
