Positive And Negative Conduct Electricity
595 wordsElectrolytes are liquids that conduct electricity. Most need to be dissolved into water or another solvent. Battery's have an electrolyte in them, either as a liquid or as a paste. Liquid electrolytes are used in electrolysis, electroplating, and other chemical processes. When electrolytes dissolve they release positive and negative ions. The released ions carry electric charges between electrodes, in the solution. Cations (a positively charged ion that migrates to the cathode, a negative electr...

Polar Bear Food Chain
571 wordsSPECIES - Ursus Maritime, Polar Bear, lord of the Arctic. Lives in an area of five million square miles of snow and ice. From Siberia to Alaska and across Canada, Greenland and the Islands north of Norway, he is the master of all living things except man. It lives in the brutal cold, ice, and snow. The temperature can plunge down frequently to - 40 degrees and sometimes even lower but that does not bother the polar bear because of its color-less skin and layer of insulation fat. Its range extend...

Disease Called Life Cycle
1,268 wordsThe phylum Myxozoa falls under the domain Eukarya and were traditionally thought of as protozoa. Within the last two decades however more advanced identifying techniques have led us to believe that they are in fact metazoan's more closely related to Cnidarians, but this will be discussed later in this essay. There are approximately twelve thousand species of Myxozoa, and it is believed that there may be more than this number. Most Myxozoa are parasites which inhabit primarily tissues and organ c...

Straight Line Physical World
1,305 wordsThe British philosopher Ryle attacked the sceptical point of view regarding right and wrong ( = being in error). He said that if the concept of error is made use of - surely, there must be times that we are right. To him, it was impossible to conceive of the one without the other. He regarded "right" and "wrong" as polar concepts. One could not be understood without understanding the other. As it were, Ryle barked up the wrong sceptic tree. All the sceptics said was that one cannot know (or prov...

Effects Of Global Warming Polar Bears
1,306 wordsEffects of Global Warming On Polar Bears and Polar Seals Introduction Polar bears depend on polar seals as a source of food in the polar region. Polar bears hunt polar seals before winter comes, so they can get all the proteins and fats they need in order to survive. Global warming is increasing the melt of ice in the Arctic region. As a result, polar seals will not be able to survive and face the environmental changes including climate. Therefore, polar bears will be threatened by starvation an...

Hydrogen Bonding H 2
502 wordsElectron Pair Repulsion Theory: The electron pair repulsion theory states that the electron pairs in the valence energy level of an atom repel each other, and therefore are arranged as far apart as possible. For example, H 2 Our to this theory, different molecules with different amounts of pairs of electrons have different shapes. Shapes of Molecules: Some common shapes of molecules include linear, trigonal planar, tetrahedral, trigonal pyramidal and v-shaped (bent) molecules. Examples are drawn...

Neural Tube Defects Children With Down Syndrome
2,759 wordsDowns syndrome is a genetic condition involving an extra chromosome, this change occurs around the time of conception. A person with Downs syndrome has forty-seven chromosomes instead of the usual forty-six. A relatively common genetic disorder, Downs strikes 1 out of 600 babies. In 95 percent of all cases, the disorder originates with the egg, not the sperm, and the only known risk factor is advanced maternal age-at age 35, a woman has 1 chance in 117 of having a baby with Downs; at 40, her odd...

Even though most people can distinguish a polar bear from a brown bear by the color of the fur, a lot of people fail to identify all the differences among those two species. Both bears can be perceived as large, clumsy and lumbering beasts with heavily bu...
