Sel (Biologi)
Dari Wikipedia bahasa Indonesia, ensiklopedia bebas
(Dialihkan dari Sel)
Sel merupakan unit organisasi terkecil yang menjadi dasar kehidupan dalam arti biologis. Semua fungsi kehidupan diatur dan berlangsung di dalam sel. Karena itulah, sel dapat berfungsi secara autonom asalkan seluruh kebutuhan hidupnya terpenuhi.
Makhluk hidup (organisme) tersusun dari satu sel tunggal (uniselular), misalnya bakteri, Archaea, serta sejumlah fungi dan protozoa) atau dari banyak sel (multiselular). Pada organisme multiselular terjadi pembagian tugas terhadap sel-sel penyusunnya, yang menjadi dasar bagi hirarki hidup.
Struktur sel dan fungsi-fungsinya secara menakjubkan hampir serupa untuk semua organisme, namun jalur evolusi yang ditempuh oleh masing-masing golongan besar organisme (Regnum) juga memiliki kekhususan sendiri-sendiri. Sel-sel prokariota beradaptasi dengan kehidupan uniselular sedangkan sel-sel eukariota beradaptasi untuk hidup saling bekerja sama dalam organisasi yang sangat rapi.

How To Make Angklung
1. THE BAMBOO ELECTIONangklung
Bamboo is the material of an Angklung. It is elected by its age. It has to be at least 4 years old and not more than 6 years old. It is cut on the dry season, between 9 am in the morning to 3 pm at the afternoon. After being cut at its base for about 2-3 span of the hand, it will be stored for about 1 week, so that the bamboo will contain less water.
After a week, the bamboo will be separated from its branches. It will be cut into certain various sizes. Then, will be stored for about one year to keep it from termites. Some of the procedures are: by sinking out the bamboo beneath mud field, pool or river, also by smoking it at the fireplace, and the modern procedure: by using a certain liquid chemistry formula.
2. SHAPING PART OF AN ANGKLUNG
Each Angklung consist of 3 parts:
The Voice Tubes
The Voice Tubes are the most important of an angklung, which produce the intonation made. Tuning process makes the intonations.
The Frame
Frame is supporting the voice tubes to stand inside the hollow space.
The Base
It is function as the frame of the voice tubes.
3. TUNING THE VOICE TUBE PROCESS
Half-Done Process
Shaping the bamboo become laths of voice tube.
Resonance Tuning Process
Blowing the lower part of an angklung to the floor and measuring it to the tuner.
Main Voice Tuning Process
Tuning the voice by increasing and decreasing the tone by strike voice. Increasing the tone by cutting its upper parts slightly, and decreasing the tone by shaping both voice laths with shaping knife.
How to Use a Tuner:
Make an attention to both of the lamps at the left and the right of the panel, and also the pointer needle.
For example, if you're going to make an "F" tone, so that when the angklung is shaking, both of the lamps will flame together, and the pointer needle will point the "F" letter.
4. FINISHING

Click on the galaxy to view it. Zoom out and begin spinning the galaxy. After a few seconds, Will Wrights' head will spin out of it.
During the Creature phase (right out of the tidal pool), you can get additional parts for your creature by impressing the alpha versions of the fellow inhabitants of your world. When you first approach them, sometimes others of their species will join in the game. The more of them there are, the more difficult it can become. Push the alpha away from the nest, and try to solo it out so that you only have to deal with him dancing, singing, etc. against your crew of followers.
Have members of other tribes in your pack before completing the Creature phase. When you advance to the Tribal phase, they will be transformed into domesticated animals in your tribe's pen.
The only sure way to get this achievement is to lure an Epic into another Epic. Note: Save your game before you get to the battle with the Epics. An Epic creature is much bigger than the usual species. It can one-shot almost anything, even though its attack range of 3-7 is not very powerful to you. Epic creatures have 1,000 health. First, get a Spit weapon with at least 4+ Spit. Spit will lure the Epic towards you, but be careful so you do not get killed. Next, have two or three Pack members (Rogue recommended). Rogues are more powerful than a normal creature, but weaker than an Epic. Rogues have 250 health and do massive damage. Spit at an Epic creature, and make it follow you. Stay at a distance, and lure it to another. Find the two you want to battle. Once they start, find the one that will probably win. Start attacking the one that is about to win. This will increase your chances of getting the achievement. Once the Epic battle is over, the Epic that won and the one you attacked should be down to about 200 health or less. If not, quit to the main menu and restart. Constantly Spit until it is down to less than 10 health. Charge it, then Strike or Bite, and you will win and get the "Epic Killer" achievement. -From: Brian Pken
