... important reminder to parents with children who suffer from this condition is
that bed-wetting should not be thought of as a behavioral problem. There is no medical
proof to show that children wet the bed to spite their parents. Also, most children will
outgrow bed-wetting eventually. As parents, the best way to help your child is to be
understanding and remember that punishing or making fun of a child who wets the bed
can only make the situation worse.
Though as of yet a cause is unknown, some doctors believe that children who wet

Changes In The Atmosphere Causing Multicellularity
Number of Words: 471 / Number of Pages: 2
... Scientists believe that eukaryotic organisms such as the protists
evolved from the prokaryotes. There are two main theories which describe how
this transition may have occurred. The first is the endosymbiotic theory, or
enosymbiosis, and the other is the autogenous theory, or autogenisis. These two
theories are not mutually exclusive, meaning one or the other could account for
different parts of eukaryotic cells. The endosymbiotic theory states that the
formation of eukaryotic cells were symbiotic associations of prokaryotic cells
living inside larger prokaryotes. The endosymbiotic h ...

... mother's pouch for 5-7
months. The term "joey² is used when you are talking about a baby marsupial.
The mother gives "pap² to the joey, a liquid from the caecum (which is similar
to the human organ, appendix.) This is thought to give the joey the ability to

... into the ocean.
Industrial, agricultural, household cleaning, gardening, and automotive products are also polluting our ocean. You wouldn't believe it but all of those products I just named regularly end up in water. About 65,000 chemicals are used commercially in the U.S. Today, with about 1,000 new ones added each year. Only about 300 have been extensively tested for toxicity. I think that since our oceans are doing so bad the U.S. should put a ban on new, and old, products that pollute the oceans.
Metals and slowly degrading chemicals threaten inland and coastal waters. Toxic materials sett ...

... mantle move? The mantle may be solid but, as with most solids, it will deform if long-term stress is applied. Presently, there are more than fourteen plates in the Earth’s crust. Upwelling hot magma flows out from mid-ocean ridges and then cools down when exposed to the cooled environment outside; the layer of cooled magma forms the lithosphere. When magma flows out from the ridges, the crust is fractured and a new ocean floor is built spreading perpendicularly away from the ridge. Because of this constant upwelling, the ocean is relatively shallow in these areas. Sea floor spreading and continental dr ...
