Why we need more food for our bodies?


Your body is made of chemicals. You get these chemicals from some food that you eat. You need food to work your muscles and other organs for connecting with your bodies.

Your food is the fuel that’s keep your moving in the activites. Just like a car can’t work without the petrol, same with your body can’t do for some activites.

As you grow, your bodies make the new cells. You also need to replace old or damage cells. Your bodies make the new cells from the chemicals in your food. That’s why we need some food for our bodies. . . . . .

Its happening process thunder
Thunder or thunderbolt constituting nature phenomena that usually emerges on rainy season whereabouts in the sky momentary light glint appearance one glares that in a little while overtook by rumbling voice. The difference this emergence time is reverential marks sense distinctive among sonic-speed and light-speed.
Thunder is nature phenomena that we can analogize with one giant capacitor, whereabouts first plate is cloud (can negative plate or positive plate) and second plate is earth (looked on by neutral). As has already known by capacitor is one passive component on series electricity one that can keep momentary energy (energy storage).
Happening thunder because available distinctive potentials among apprehend and earth. It’s happening process content on apprehends since she moves to pierce through and through regularly, and up to move it she will get interaction by apprehends another so negative charge will congregate on single-sided false (on or down), meanwhile flock positive charge on the side contrariwise

Finally, this artery clear sap collected together in to artery big limfa is artery limfa left and artery limfa right. The artery limfa left or chest empties into vena. Likewise, the artery limfa right. Artery limfa channels around 100 ml clear sap into vena for return into blood, with this procedure the clear sap along with the contents protein return to blood current.

HOW CAN RAIN HAPPEN

we know together that rain is one of weather. but some people don't know about the cycle of the rain. Now I will explain the cycle of rain.
first rain happen because of water avoporated. then the water particle up to the sky. it happen because air always go to sky, where the air pressure is low. because the air pressure is low, the water particle is freeze and become ice particle. the ice particle become many and be a cloud.
when it become a cloud, the wind blow it to the top of land surface. becuse the particle form is ice, it be more weight. and it fall to the land. it happen continuosly.

Book
As we know, books are important things for human not only for students, but also for people generally. Books are purpose as a media that used to writing something, to get information, and also for communication medias. Now, we can get many books that we want, easily and also with cheap price. But, where is the book come from??
Many people said that the first book is leaves. The others also said that the first books are stones. In fact, that’s true. The scientist said that our ancient use stone and also leaves as the first book. They used chalk stone to write in stones. And in early 1800, they invented paper. They think if their using stone, the reader, cannot read text well. So, they invented print machine.
The main object to make paper same with object to make sugar. That’s “tebu”.They using “ampas tebu” to make a paper. Then, in paper producing machine, this “ampas tebu”, processed to be paper. Finally, that paper will sent to another factory. There, they write the text.

Nitrogen in air can diffusion into soil with process amonofication to NH4. The N2 other way in air fixed with Rhizobium bactery which can use for legumminose plants.
Organic molecule which come from plants and animal will decomposition to be with ammonium NH4. Ammonium in the soil will nitrificated be NO3. Plants can absorb Nitrogen in NH4 or NH3 form. NH3 is toxic for plants. Nitrificated bactery have to kind they are Nitrosococcus and Nitrobactery.

HUMAN GENOME


A genome is DNA in an organism, including its genes. Genes carry information for making all the proteins required by all organisms.
DNA is made up of four similar chemicals (called bases and abbreviated A, T, C, and G) that are repeated millions or billions of times throughout a genome. The human genome, for example, has 3 billion pairs of bases. The particular order of As, Ts, Cs, and Gs is very important. The order underlies all of life's diversity, even dictating whether an organism is human or another species such as yeast, rice, or fruit fly, all of which have their own genomes and are themselves the focus of genome projects. Because all organisms are related through similarities in DNA sequences, insights gained from nonhuman genomes often lead to new knowledge about human biology.

PostSubject: Explanation by Dwiniata Palilu Natural Science 1   Wed Mar 18, 2009 4:56 am

Snow


It begin when the steam assemble in atmosphere. At the condensation point, the droves of steam become lump up and the cloud is formed. At the beginning of cloud establishment, the mass of cloud is less than air mass, so the cloud is floating on air. But when the mass of cloud is increase and becomes more weight because the drove of steam is increase constantly, the air cannot hold the cloud and the cloud is smashed. After that, the water particles fall down to earth.


The falling water particles were not dirtied by other particles (pure water). On temperature 0˚C, the pure water freezes indirectly, because on temperature 0˚C, there is a change of phase from liquid to solid. To make a faster phase change, the substances have to be added by certain substances, for example is salt which used in liquefaction of ice to become water.

Usually, air temperature below the cloud is less than 0˚C, which depends on the height from oceanic water surface. But, the low temperature is not enough to establish snow. There are some particles that could help to accelerate in freezing phase, so the pure water becomes frost quickly. The water particles combine with other water particles and become bigger. If the air temperature could not melt the frosts, it will fall to earth as snow.

The difference between Reaction rate concept and Equilibrium concept
The reaction rate is defined either as the increase in the concentration of a product per unit time or as the decrease in the concentration of reactant per unit time. The first of determining a reaction rate is to establish the reaction order. The next step is to evaluate the numerical value of the rate constant. We define reaction rate in term of concentration(moles per liter) rather than amount(moles) because we want the rate to be independent of the scale of the reaction . When we increase the volume of reactant twice, but the concentration is Constant.
Le Chatelier Principle : if a stress is applied to a reaction mixture at equilibrium, reaction occurs in the direction that relieves the stress. An increase in pressure by reducing the volume will bring about net reaction in to the direction that decreases the number of moles of gas of the coefficient of reaction. On contrary, a decrease in pressure by increasing the volume will bring about net reaction into the direction that increases the number moles of gas or the coefficient of reaction. Because gas pressure are easily measured, equilibrium equations for gas-phase reactions are often written using partial pressures rather than molarity.

WHALE




Whale is the biggest fish in the world. They also a mammal. They can bear their children without egg. They can eat million planktons once in a swallow. They live in ocean and the deepest sea. They can’t lives near island because they can’t catch million planktons. So, for catch million planktons, they must lives in ocean and the deepest sea.
Whale can make some communication with their friends or their parents. If they will be attacking by some predators, they can send signals to their friends or their parents for request some help.
But now, many people like to catch whale because people make whale to be a perfume. They also catch whale for sell their meat. So, whale will be threatened to extinct. Population from whale ground one thousand whales in the world.

Process that happen wind…,
Wind have relation with sun ray because territory that have many sun ray shelf will have temperature that more high and low air pressure than another territory in that around until bringing be air current. Wind also can motive from thing moval until air boosting in that around to budge to another place.
In a simple, wind can we make with using palm of hand, fan, etc. Whereas in a crucial, wind can we make with fan electic, hair dryer, etc. In a natural, we can using with mulut, nose, etc for make a wind.
Air can carry scent particle from a certain essence until wind can carry the essence from essence delicious until essence not delicious in our nose. Food essence, oor of fish essence, sea essence, rubbish essence, gasoline essence, flatus essence, feces essence, and another example essence that carry wind.

TEETH

Teeth are tools. There are four kinds of teeth. And each kind has a special job to do. You use teeth to cut, tear, chew, and grind food. Your teeth break down food into small pieces. Then, the small pieces. Then, the small pieces can be swallowed. This one reason why teeth are so important.
Your teeth will do a good job for you. But you must take care of them. Brush after every meal. Visit the dentist twice year.

Voice
Respiration system on human really gets bearing with process to result the voice. First, the air input goes to nasal cavity then be kept on to pharynx. The air from pharynx will be kept on to larynx.
At larynx, available voice membrane. This membrane has muscle fiber so get to result voices. So, voice that we results will come out after air gets to larynx. Usually, when the other people give shocking to us, we can’t issue voice, because no ingoing air. Because we have voice, we can speak.

Why a Zebra has stripes

One day Mr. and Mrs. Zebra were going to a party with all there other Jungle friends. Mr. and Mrs. Zebra both wanted to look very special, but in a different kind of way.

Mr. Zebra painted the front part of himself green, like the lizard. You see they were all white back then. Mrs. Zebra painted the back part of herself a tan color, like the lion.

Mr. Zebra didn't like the way that Mrs. Zebra looked. Mrs. Zebra didn't like the way that Mr. Zebra looked. So they talked about it and decided that they liked black, as there color.

Mr. Zebra painted the front part of himself black. Mrs. Zebra painted the back part of herself black. They looked at each other and both had an instantaneous thought, "Stripes!" They said together. They each painted them selves in stripes and went to the party later that night.

Everyone at the party loved there new creation of an outfit!

They got plenty of compliments and were even complimented by the king of the jungle, Mr. Lion. He thought they were very creative.

The party ended late that night, but talk of Mr. and Mrs. Zebra's outfit kept going well into the morning. Soon all the Zebras, in the jungle, were painting them selves in stripes. Soon Zebras all around the world were doing it to.

After awhile Mr. and Mrs. Zebra got tired of stripes. But when they tried to wash off there stripes they found that the paint had sunk in well beyond there fur. They couldn't get it off for anything. Soon all the Zebra's started getting tired of stripes. But they couldn't get there's off either!

To this day the Zebras still can¹t get there stripes off. That is why the Zebra has stripes!

The End

What Are Clouds And Why Does It Rain?

Almost all the air around us is moist. That means that it contains water in the form of vapour. You can't see it because water vapour is a gas, but it's still water. Water can exist in three states : liquid (water), solid(ice) and gas(water vapour). Obviously, you can see and touch water and ice, but water vapour has no smell, you can't pick it up, and it's invisible. That doesn't mean that you can't feel it though.

Go outside and stare up at a cloud (not one right next to the Sun though - you don't want to go blind!). Watch that cloud for a while, especially it's edges. As you watch it, the edges will change, either growing larger or getting smaller. What you are seeing is cloud formation in action. As the cloud grows you are seeing more of those water droplets condensing out of the air, and as it shrinks, you are witnessing the droplets evaporating - changing from visible liquid water into invisible water vapour.

Now, it doesn't take a genius to point out that the clouds are usually a long way up, and not every cloud has rain pouring out of it. So, how does the formation of a cloud lead to actual rain?

To get rain, the water condensing in the clouds has to become heavy enough to fall to Earth. The tiny droplets just aren't heavy enough to fall. Just like fog or in the shower, they go whichever way the wind and eddy currents blow them, or they just hang there, suspended in the air.

So, there you go - now you know what a cloud is, and how it creates rain.

To create clouds, and to have rain, the air has to be cooled. There are three main ways in which this happens in the atmosphere, and every geography student needs to know, and understand, all three of them.
