Recognize Bacterial

The first bacterium discovered by Anthony van Leeuwenhoek in 1674 using a homemade microscope. The term bacterium was introduced at a later date by Ehrenberg in 1828, taken from the Greek word βακτηριον which means "small stick".

Bacteria, from the Latin word bacterium (plural, bacteria), is the largest group of living organisms. They are very small (microscopic) and mostly unicellular (single celled), with a relatively simple cell structure with no nucleus / nucleus, cytoskeleton, and organelles such as mitochondria and chloroplasts. Their cell structure is described further in the article about prokaryotes, because bacteria are prokaryotes, to distinguish them from organisms that have more complex cells called eukaryotes. The term "bacteria" has been applied to all prokaryotes or to a large group of them, depending on ideas about their relationship.

Bacteria are the most abundant of all organisms. They are spread (being everywhere) in soil, water, and as symbionts of other organisms. Many pathogens are bacteria. Most of them are small, usually measuring only 0.5 to 5 μm, although there are species can reach 0.3 mm in diameter (Thiomargarita). They generally have cell walls, such as plant and fungal cells, but with very different composition (peptidoglycans). Many who move using flagella, which differ in structure from the flagella of other groups.

Bacteria cell structure

As prokaryotes (organisms without nucleus membrane) in general, all bacteria have a relatively simple cell structure. Structure is the most important bacterial cell wall. Bacteria can be classified into two groups: Gram positive and Gram negative based on differences in the structure of the cell dinging. Gram positive bacteria have cell walls composed of thick layers of peptidoglycan and teichoic acid. While Gram-negative bacteria have outer layer, lipopolysaccharide - consists of a membrane and a thin peptidoglycan layer located on periplasma (in between the outer layer and cytoplasmic membrane).

Many bacteria have structures outside the cell such as flagella and fimbria that is used to move, stick and conjugation. Some bacteria also have a capsule or slime layer that helps the bacteria on a surface attachment and biofilm formation. Bacteria also have a chromosome, ribosomes, and several other species have granules of food, gas vacuoles and magnetosom.

Some bacteria can form endospores that enable them to survive in extreme environments

Saturn

Saturn is a planet in the solar system known also as the ringed planet. Saturn is very far distance from the Sun, because that Saturn did not seem very clear from the Earth. Saturn evolved in 29.46 years. Every 378 days, Earth, Saturn, and Sun will be in a straight line. In addition to evolve, Saturn also rotates in a very short time, which is 10 hours 14 minutes.

Saturn has a low density because most of the constituent substances in the form of gases and liquids. Saturn's core is estimated to consist of solid rock with atmospheric gas composed of ammonia and methane, it is not possible life on Saturn.

Saturn's rings are very unique, consisting of thousands of rings around the planet. Ring-forming material is still unknown. The scientists suggest that the ring was not possible because it is made of solid slabs will be destroyed by centrifugal force. However, it may also be made of the liquid due to centrifugal force will lead to the emergence of a wave. So far, it is estimated that the most likely form the rings are chunks of ice meteorite.

Until 2006, Saturn has 56 known natural satellites of fruit. Seven of them massive enough to be spherical collapse under its own gravity. They are Mimas, Enceladus, Tethys, Dione, Rhea, Titan (largest satellite with a size larger than the planet Mercury), and Iapetus.

Physical Form

Saturn has a shape that is flattened at the poles, and dibengkakkan out around the equator. Saturn's equatorial diameter of 120 536 km (74 867 miles) where the diameter of the North Pole to South Pole for 108 728 km (67 535 miles), differ by 9%. Flattened shape is due to the very fast rotation, rotating every 10 hours 14 minutes of Earth time. Saturn is the only planet in the solar system density less than water. Although the core of Saturn has a density greater than water, the planet has an atmosphere containing gas, so that the density of the relative planet for is 0.69 g / cm ³ (less than water), as a result, if Saturn is placed above pond full of water , Saturn would float.

Adjective or Relative Clauses

Adjective clause is also called the Relative Clause is part of the sentence (clause) that provide information on the person or thing that preceded it. Relative terms similar to Clause Adjective Clause. Called Adjective Clause because he explains things or people that preceded it.

"However, they need to understand why we do it," he said. Selvasegaram said the past six months, Microsoft has received 369 complaints and reports from consumers. "They reported the problem on their computers that are installed pirated software," ujarnya.Selain, according Selvasegaram, a number of consumer and PC dealer who has always install the original software also approached Microsoft. "They asked what steps we did to chain stores that offer pirated software," he said.

Selvasegaram said, the dealers could not compete honestly admitted. "If we do not take the initiative, consumers will suffer the consequences, honest dealer can go bankrupt," said Selvasegaram. "We will be firm but fair and give priority to establish the principle of mutual respect," he said.
