We have not yet determined which Kleenex Project we will do. What I want to do my project on is how absorbent a Kleenex Tissue, how many sneezes it can withstand, and how much mucus comes out in one sneeze. We can then determine how much mucus comes out in one sneeze, then we can see how many sneezes a tissue can withstand, and how absorbent it is. If Kleenex was to advertise there product, they can say that there tissues are good for a number of sneezes, and they can say that there tissue can hold possibly 10 ounces of mucus. I'm not sure if these numbers are accurate, but I hope you can understand what I am trying to say.
Antarctica used to be close to the equator, and life would be abundant. As Antarctica drifted away to the location it is today; plants died, and most of them were destroyed, but some of them fossilized. The plants scientist have found are plants that grow in temperate regions. This helps support that Pangaea existed, it also supports continental drift since it was able to drift away to the location it is today, and it helps support the theory "plate tectonics".
It took Antartica about 265 million years from somewhere close to the equator where it was warm to where it is today and freezing. Now Antarctica is melting and over time Antarctica will eventually be located in a temperate region close to the equator. To determine an old unfossilized bone, I would use the Carbon-14 method. If the fossil was very old, it would be fossilized, but it isn't so that quickly eliminates the Uranium-Lead method and it also eliminates the Potassium-Argon method as well. If the fossil was old enough to use the Potassium-Argon method, it would have been at least 1.3 billion years ago. I know that there were only single celled and multicellular organisms that point of time so Potassium-Argon is eliminated.
The half-life of radioactive Uranium is 4.5 billion years. The oldest rock on Earth dates back to 3.5 billion years ago when the Earth was finally cool enough. The Uranium-Lead would only be used for asteroids or objects in space. Even if the bone dated was 1.3 billion years old, chances are it would have most likely been destroyed since it is not preserved. Charles Darwin is one of the founding fathers of evolution. Charles Darwin went the Galapagos islands off the coast of Soth America. Charles Darwin observed that the finches on the Galapagos islands were very similar to the finches on South America. The only major difference were there beaks. The Galapagos islands are made up of many islands which have different resources. The finches on these different islands have adapted to their environment and are different from the other finches on the other islands. One of these adaptations was a large beak which was used to crack things. Islands that did not have resources like almonds for example which have shells did not have finches like these.
Finches on different islands were no longer able to interbreed which means they became their own species and reproduce among themselves. Wallace helped Charles Darwin determine that if a trait helps an animal survive and that trait is passed on. If a finch with a mutation was able to survive on the Galapagos Islands, that mutation would be passed onto future generations and it is dominant and eventually a new species may occur. | AuthorI like to play the chinese yo-yo which is also called a diabolo ArchivesJune 2013 Categories |
