Fungi, most plants are foreign. The biologist does not consider it as a plant. Fungus does not have roots and a fixed rod. Fungi also does not have any leaves or flowers and are not able to seed. Fungus does not make their own food because they do not contain chlorophyll leaves. Then how mushrooms grow, and what is eaten by fungi which can grow?
As a seed, spore fungus produces millions of very small spots, such as dust which is very small. Sporidium be blown away from the parent plant by wind. If the spore get in the right place, it will grow into new fungi. Part of the mushroom that we see on the ground called "the body of the bear." However, this is only about a tenth of mushroom. All fungi are made of yarn is very small, which is called "hyphae". Some of them are developed together to create a body that bear fruit. More to the running down to the ground or in trees and other surfaces. This thread is taking food from plants or animals that live and die. Fungus from the root of life of fruits, leaves the dead, and also the human body. Skin diseases due to water lice and ringworm caused by fungi. Fungi also make bread and fruit decay.

Calculating AGE Tree
Layer of tree sap from new growth timber in the form of a ring. With the ring-ring on a tree trunk cut off, we can know the tree's age. When we entered the forest, see the fallen tree ring-Count and its annual rings.
We can also find out the weather that has occurred in the past with a view of trees cut. When the width of the ring, it means that in the past often rain. Meanwhile, when the adjacent ring forms, in the past means that the rare rain. However, the tree can grow to the weight in the art, that is when the weather is hot but still moist.
In addition to calculating its annual rings, we can also know the age of the tree with the measure around the tree. Most trees grow with the thickness approximately 2.5 cm per year. So, to be able to know the age of the tree, and measure around the trunk from 1.5 meters below ground. After knowing the tree circumference, and divide kelilingnya of 2.5 cm so that the tree age is known. For example, if the tree is around 125 cm, the age of the tree is 50 years (125 divided by 2.5 equal to 50).

Yahoo!
Yahoo! That we know as one of the search engines, Web portals and service providers e-mail from the beginning the biggest hobby two founders, David Filo and that Jerry Yang when they were still demanding science at Stanford University.
David and Jerry are all initiated in February 1994 when they began to gather a list of links to favorite sites they visit frequently on the Internet. After some time, the list is too long to be collected and knowledgeable. For that, they divide the lists into multiple categories and re-link to other links. After listing on each category is also the full, they return to them in the sub-category, and this is the core concept of the web portal Yahoo!.
Website that was initially called "Jerry and David's Guide to the World Wide Web" which is then given Yahoo! which is the abbreviation of "Yet Another Hierarchical Officious Oracle." Yahoo! This alone saved the first time in Arkebono, workstation Jerry Yang, while the software is stored on Konishiki, a computer owned by David Filo. Arkebono and Konishiki own taken from the name of the legendary pegulat Sumo. Did you where Jerry and David keep their sites first? URL address of the first Yahoo! itself is http://arkebono.stanford.edu/yahoo.
In fact Jerry and David is not the only people who want a place to start to find information on the Internet. Not long after, hundreds of people began to access their site. Information that is spread from mouth to mouth about the site made Jerry and David hit this eventually reach 1 million in their first autumn 1994. Only after some not established.
In 1995, Jerry-David duet successfully lobbying Sequoia Capital to invest around 2 million U.S. dollars to Yahoo!. After that, they recruited Tim Koogle as Motorola's Chief Executive Officer and Jeffrey Mallett (application of WordPerfect owned by Novell) as Chief Operating Officer. In the fall of 1995, they successfully get back investors, namely Reuters Ltd. and Softbank. Yahoo! end of its own stock to shareholders in April 1996 is not. Total employees at the time they amounted to 49 people.
