TANGISAN HATI SEORANG ANAK PEREMPUAN
YANG TERMENUNG DI GELAPNYA MALAM
MEMANDANG INDAHNYA BINTANG
HANYA ADA PERASAAN SEPI DAN SUNYI
HANYA KENANGAN YANG KU INGAT
SAAT BERSAMANYA
SAAT TERTAWA DENGANNYA
MENATAP INDAHNYA MASA DEPAN BERSAMANYA
TAPI KINI, TAK ADA LAGI MASA-MASA ITU
KINI HANYA ADA SENYUMAN YANG SLALU KU INGAT DI DALAM HATI
DAN NASEHAT-NASEHAT YANG IA BERIKAN
DAN KINI, HANYA ADA UNTAIAN DOA UNTUK MEMBAHAGIAKANNYA

TITAN
The Titan is one of the 18 Saturn's satellities. It was discovered by Christiaan Huygens, a Dutch astronomist, in 1655. Huygens also discovered the Saturn's rings, a spectacular appearance observed by Galileo Galilei. The visual observation done by Jose Comas Sola in 1908 indicated the density of Titan's atmosphere. Chemically, the condition of this satelite is believed to be similiar to that of the Earth about 4.5 billion years ago. The difference between the two is that the Titan is much colder than the Earth.
From the infrared spectrum, in 1944, Gerard Kuyper, an American astronomist, a Dutch origin, successfully identified the methane compound in its atmosphere. Then, at the beginning of 1970, Lewis clarified the possibility of the existence of nitrogen. In 1980 Voyager I, another spacecraft, approached closer to this satelite and sent its observation about its atmospheric temperature, pressure and composition.

CHARACTERISTICS OF PROTOZOA
Protozoa,minute,aquatic creatures each of which consists of a single cell of protoplasm,consitute a classification of the most primitive forms of animal life. They are fantastically diverse,but three major groups may be identified on the basis of their motility. The mastigophora have one or more long tails, which they use to project themselves fordward. The Ciliata, which use the same basic means for locomotion as the Mastigophopra,have a larger number of short tails. The Sardocina, which include amoebae,float or row themselves about on their cursted bodies.
In addition to their form of movement, several other features discriminate among the three groups of protozoa. For example,at least two nuclei per cell have been identified in the Ciliata,usually larger nucleus that regulates growth but decomposes during reproduction,and a smaller one that contains the large nucleus.
Protozoan are considered animals because,unlike pigmented plants to which some protozoans are otherwise almost identical,they do not live on simple organic compounds. Their cell demonstrates all of the major characteristics of the cells of higher animals.
Many species of protozoans collect into colonies, physically connected to each other and responding uniformly to outside stimulate. Current research into this phenomenon along with investigation carried out with advanced microscopes may necessitate a redefinition of what constitues protozoans,even calling into question the basic premise that they have only one cell. Nevertheless, with the current data available,almost 4.000 species of protozoans have been identified. No doubt,as the technology improves our method of observation, better models of classification will be proposed.

ALGAE
Alagae is a primitive form of life, a single-celled or simple multiple-celled organism that is able to conduct the process of photosynthesis. It is generally found in water, but can also be found elsewhere, growing on such surface as rocks or trees. The various type of algae are classified according to pigment.
Characteristics of algae:
1. Blue-green algae, or Cyanophyta, can grow at a very high temperature and under intensity of light. This type of algae is the oldest form of life with photosynthesis. Fossilized remain of blue-green algae more than 3.4 billion years old have been found in parts of Africa.
2. Green algae, chloropyta, is generally found in fresh water. It reproduces on the surface of a enclosed bodies of water such as ponds or lakes and has the appearance of a fuzzy green coating on the surface of the water.
3. Brown algae, or phaeophyta, grows in a shallow, temperate water. This type of algae is the largest in size and most recognizable as a type of seaweed. Its long stalks can be enmeshed on the ocean floor, or it can float on the ocean's surface.
4. Red algae,rhodophyta, is a small delicate organism found in the formation of coral reef:it secretes lime from the sea to foster the formation of limestone deposits.

Bagaimana Ikatan Hidrogen Mengapungkan Es?
Air memiliki sifat-sifat yang unik. Satu di antaranya, yaitu air dalam bentuk cair lebih padat daripada air yang membeku(es). Padahal, sebagian besar zat di Bumi lebih padat dalam bentuk padatan dibandingkan bentuk cairan.
Bagaimana fenomena tersebut terjadi? Ikatan hidrogen inilah yang mencegah molekul-molekul air dalam es berikatan sangat kuat. Akibatnya, terdapat banyak rongga di antara molekul-molekul air dalam es. Ikatan hidrogen ini terurai ketika es mencair. Dengan demikian, molekul-molekul air dapat berinteraksi lebih dekat dan membentuk struktur yang lebih padat. Banyaknya rongga dalam struktur es menyebabkan es lebih ringan dibandingkan air. Itulah sebabnya, es mengapung di atas air.

AIDS
Aids is a set of symptoms and infections resulting from the damage to the human immune system caused by the HIV. This condition progressively reduces the effectiveness of the immune system leaves individuals susceptible to opportunistic infections and tumors. HIV is transmitted through direct contack of a mucous membrane or the bloodstream with a bodily fluid containing HIV, such as blood, vaginal fluid, preseminal fluid and breast milk.
The two main transmission routes of HIV are sexual contact, and exposure to infected body fluids.
1. Sexual contact
The majority of HIV infections are acquired through unprotected sexual relations between partners, one of whom has HIV.
2. Exposure to infected body fluids
Health care workers can reduce exposure to HIV by employing precautions to reduce the risk of exposure to contaminated blood.
The symptoms of AIDS are primary the result of conditions that do not normally develop in individuals with healty immune system. Most of these conditions are infections caused by bacteria, viruses, fungi and parasites that are normally controlled by the elements of the immune system that HIV damages. Opprtunistic infections are common in people with AIDS. HIV affect nearly every organ system. Additionally, people with AIDS often have systemic symptoms of infections like fevers, sweats (particularly at night), swollenglands, chills, weaknes, an weight loss.
