Answer:
All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Cell division is tightly regulated because the occasional failure of regulation can have life-threatening consequences.

Explanation:
Sodium (Na) and Chlorine (Cl) are two electrolytes that play important role in the absorption of water and nutrients in the small intestine. However, as mentioned in the question, the release of sodium and chlorine would lead to a loss of water in the intestines. This is because of the OSMOTIC phenomenon.
Osmosis is the movement of water molecules from a region of high concentration of water/low concentration of solute to a region of low concentration of water/high concentration of solute via a semipermeable membrane. In this case, the Na+ and Cl- ions serve as the solutes, which when released out of the intestine causes the solution in the intestines to be HYPOTONIC compared to the intestinal environment. This causes an OSMOTIC GRADIENT.
This osmotic gradient i.e. difference in concentration provokes osmotic flow of water from the intestines, which has a low solute/high water concentration, to the outside of the intestines, which has a high solute/low water concentration. Hence, water is lost from the intestine because the solute concentration becomes low when sodium and chlorine ions are released.
Phosphates generally come from fertilizer, erosion of phosphate-containing rocks. they are fertilizers, so they tend to strongly encourage growth, particularly of bacteria and algae. This can harm ecologies, particularly in water, and particularly where there isn't a very robust growth medium already, e.g. in cold or desert waters.<span>This impacts the environment and our health because we use tap water for cooking, bathing, brushing teeth, and etc. and these water by be contaminated because of all of this pollution going around</span>
They give us the energy we need to move and to speak and to live they do that for all the organisms on earth
The given blank can be filled with selecting.
It has been shown by Belyaev and Trut that foxes can be domesticated, over the time of various generations, by selecting and mating animals with certain traits, like responses to feeding, handling, and others.
A sustained multi-generational association in which one group of species presumes a substantial extent of effect over the care and reproduction of another group to secure a more predictable supply of resources from that latter group is known as domestication.
