A great suggestion from many readers, this fight pits two of the coolest animals on Earth in battle.

The American alligator normally grows up to 12-15 ft and weigh over 1000 lbs. The Alligator has been known to take down prey as large as a Black Bear. It has the strongest bite force of any animal on Earth and is the apex predator of its habitat.

The biggest Komodo Dragons can grow up to 12 ft and weigh in at 250 lbs. Found only in remote islands of Indonesia, the dragon takes down prey up to 10 times its size, including water buffalo. The Komodo Dragon has no fear of any animal and its saliva contains a deadly mix of bacteria.

This animal fight might well come down to who gets the first bite. If the gator were able to get a clean shot at the dragon, it could snap it in half. However, it says here that the Komodo Dragon will get the first bite 9 out of 10 times, on land or in the water, letting its "venom" kill the alligator and then devouring every bit of it.

Be Carefull, High Toxic

Recent cold temperatures would likely cause the snake to seek a warm and safe hideout, according to herpetologists following the case. Zoo officials plan to wait the snake out until it gets hungry and thirsty, which could take time since snakes can go months without eating and weeks without drinking.

Egyptian cobras can grow to 6 feet long, dine on rodents and carry deadly neurotoxic venom that can kill a human within minutes, causing respiratory failure.

Sean Kingston - Beautiful Girls

Chorus:
You're way too beautiful girl
That's why it'll never work
You'll have me suicidal, suicidal
When you say it's over
Damn all these beautiful girls
They only wanna do your dirt
They'll have you suicidal, suicidal
When they say it's over

See it started at the park
Used to chill at the dark
Oh when you took my heart
That's when we fell apart
Coz we both thought
That love lasts forever (lasts forever)
They say we're too young
To get ourselves sprung
Oh we didn't care
We made it very clear
And they also said
That we couldn't last together (last together)

See it's very define, girl
One of a kind
But you mush up my mind
You walk to get declined
Oh Lord...
My baby is driving me crazy

Chorus

It was back in '99
Watchin' movies all the time
Oh when I went away
For doin' my first crime
And I never thought
That we was gonna see each other (see each other)
And then I came out
Mami moved me down South
Oh I'm with my girl
Who I thought was my world
It came out to be
That she wasn't the girl for me (girl for me)

See it's very define, girl
One of a kind
But you mush up my mind
You walk to get declined
Oh Lord...
My baby is driving me crazy

Chorus

Now we're fussin'
And now we're fightin'
Please tell me why
I'm feelin' slightin'
And I don't know
How to make it better (make it better)
You're datin' other guys
You're tellin' me lies
Oh I can't believe
What I'm seein' with my eyes
I'm losin' my mind
And I don't think it's clever (think it's clever)

You're way too beautiful girl
That's why it'll never work
You'll have me suicidal, suicidal, suicidal...

Bruno Mars "Just The Way You Are"

Oh her eyes, her eyes
Make the stars look like they're not shining
Her hair, her hair
Falls perfectly without her trying
She's so beautiful
And I tell her every day
Yeah I know, I know
When I compliment her
She wont believe me
And its so, its so
Sad to think she don't see what I see
But every time she asks me do I look okay
I say
When I see your face
There's not a thing that I would change
Cause you're amazing
Just the way you are
And when you smile,
The whole world stops and stares for awhile
Cause girl you're amazing
lyricsalls.blogspot.com
Just the way you are
Her nails, her nails
I could kiss them all day if she'd let me
Her laugh, her laugh
She hates but I think its so sexy
She's so beautiful
And I tell her every day
Oh you know, you know, you know
Id never ask you to change
If perfect is what you're searching for
Then just stay the same
So don't even bother asking
If you look okay
You know I say
When I see your face
There's not a thing that I would change
Cause you're amazing
Just the way you are
And when you smile,
The whole world stops and stares for awhile
Cause girl you're amazing
Just the way you are
The way you are
The way you are
Girl you're amazing
Just the way you are
When I see your face
There's not a thing that I would change
Cause you're amazing
Just the way you are
And when you smile,
The whole world stops and stares for awhile
Cause girl you're amazing
Just the way you are

Johannes Kepler

2010-09-27T20:20:00.002+07:00

Austrian mathematician and astronomer who got himself taken on as an assistant to Brahe in order to get access to his planetary tables. Kepler had been trained as a Platonist and Neopythagorean, and was given to rather mystical views, as exemplified in his work Mysterium Cosmographicum. Nevertheless, Kepler was also a confirmed Copernican. In fact, he wanted to use Tycho's data to prove the validity of the Copernican theory. He analyzed the vast amount of data upon Brahe's death. From this data, he prepared new planetary tables (called the Rudolphine Tables). At first, he determined the shape of planetary orbits to be ovoid, but rejected this result for aesthetic reasons. Going back over his calculations, he found and corrected an error. The new shape turned out to be an eclipse, which fit well into Kepler's Phytagoras views on nature.

Kepler tried all sorts of mystical notions to describe planetary orbits, using the Platonic solids and musical analogies. Spread out through his voluminous calculations in Astronomia Nova, however, were three gems: Kepler's laws of planetary motion. For the formulation of these laws, Kepler is considered the founder of physical astronomy. The first law states that the planets move in elliptical orbits with the Sun at one focus The second law states that the planets sweep out equal areas in equal times (which is equivalent to the statement of conservation of angular momentum) The third law states that the period squared in proportional to the semimajor axis cubed. Kepler believed that the planets were kept in their orbits by a "anima motrix" (motive soul), but later modified it to "vis motrix" (life force). He also studied optics as an aspect of astronomy in Astronomiae Pars Optica (1604), and developed the concept of a ray.

Muscular System

A popular and traditional Halloween costume is that of a skeleton. Could a skeleton really walk by itself? What do you think? In the bone section of KidsBiology.com we learn that skeletons have the important job of providing our bodies with strength and form. The task of moving our bodies from one place to another belongs to another part of our bodies known as muscles. Without muscles we could not move.

H2O

2010-09-22T21:13:00.002+07:00

Everyday we see the same whose name the water, what water ?

Water (H2O) is the most abundant compound on Earth's surface, constituting about 70% of the planet's surface. In nature it exists in liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at standart temperature and pressure. At room temperature, it is a nearly colorless with a hint of blue, tasteless and odorless liquid. Many substances dissolve in water and it is commonly referred to as the universal solvent. Because of this, water in nature and in use is rarely pure and some of its properties may vary slightly from those of the pure substance. However, there are many compounds that are essentially, if not completely, insoluble in water. Water is the only common substance found naturally in all three common states of matter and it is essential for life on Earth. Water usually makes up 55% to 78% of the human body.

pH meter

2010-09-21T18:05:00.001+07:00

Lacking a pH meter, water is pH-tested by adding chemical agents to a water sample. Depending on the agents used, a bright yellow result could indicate highly acidic water; blue, neutral; and deep brown, alkaline water. Hues are interpreted as positions along the scale.
Liquid pH tests can be messy and they do require some guesswork as to the reading. Conversely, a pH meter is a digital device with a connected glass electrode probe. The probe is placed into the water to be tested, and the pH of the water is digitally displayed. It takes mere seconds and is far more accurate, assuming the pH meter has been properly calibrated.
Though there are many types of pH meters, common varieties will come with calibration liquids called buffer solutions. These solutions are predetermined to be highly acidic (4.01), neutral (7.01), and alkaline or base (10.01).
Calibration is accomplished by testing the liquids with the probe and adjusting the meter’s readings. A pH meter should be recalibrated monthly for best results. When not in use, the tip of the probe must be stored in acidic solution. If the probe dries out, it will need replacement.
Water quality controllers commonly use pH meters. Other types of pH meters test solids like soil or even foods. Many aquarists use pH meters in lieu of liquid testing. The probe can be placed permanently in an aquarium sump and the meter, mounted inside the aquarium stand or on a nearby wall. Freshwater cichlids and saltwater fish require alkaline water, while African Nile fish thrive in acidic freshwater. In an aquarium, pH fluctuation can cause illness or death to fish, so monitoring pH closely is paramount.

Alpine Skipper

2010-09-19T11:42:00.000+07:00

My first task tomorrow is to collect butterflies

About Alpine Skipper

The Alpine Skipper is found throughout the Indo-Australian region. This includes New Zealand, Australia and southern Asia. In the early stages, the caterpillar is greenish-gray striped. It feeds on sedge which is a grass-like plant that grows in wet places. The butterfly is dark brown on the top side of the wings with yellow-orange spots. The underside of the wings are mainly yellow with a brown spotted pattern which provides camouflage when the butterfly is feeding from yellow plants.

Carolus Linnaeus

2010-09-18T14:48:00.000+07:00

Carolus Linnaeus, 1707-1778, is a Swedish physician. He had interest in studying plants. He observed and noted the characteristics of different types of plants he found. Based on the similarities and differences in the plants, he made classification. Linnaeus published Species Plantarum in the dsitinguished Systema Naturae that includes organism classification. Because of this works, he is known as the founding father of classification (taxonomy)

Symbols in Laboratory

2010-09-18T14:21:00.000+07:00

Pelajaran yang saya peroleh hari ini adalah tentang simbol-simbol yang sering kita jumpai di ruang laboratorium, kemanan tu penting yang nggak friend....Nah agar saat kita berada di ruang laboratorium nggak celulak celuluk (kaya kebo getu) ada baiknya teman2 tau apa makna dari lambang2 tersebut, wokey....

radioactive

yang ini simbol bahaya radioaktif, kayak uranium getu....

flammable

yang ini namanya flammable artinya mudah terbakar

kalo yang ini kita semua nggak boleh melakukannya, baik sekedar mencoba atau buat gagah2an....ruang lab bisa pengap....hehehehe...yang ini nggak cuma di lab, di pom bensin dan ruang pak kepsek juga ada kok...

Rachel Carson

2010-09-18T13:53:00.000+07:00

After the World War II, many types of new insecticides came to the market, including DDT, which is worshipped as the main weapon in the war to combat pest and to increase harvests. Nobody considered the effect that insecticides may cause, which cannot be decompossed naturall by the soil and other organisms. In 1962, a book written by an American marine biologist, Rachel Carson (1907-1964), entitled Silent Spring attracted many people on the destructions caused by these chemicals. In her book, Carson presented an evidence that insecticides do not kill the pest only. The secondary consumers predate insect that are infected by the chemical sprays and therefore this accumulates pesticides in the bodies of the secondary consumers. The chemicals accumulate more in every increasing rank of thropic pyramid so the danger seriously threats the organism in the top of food web, including human beings. Carson wants that not only time will come when the song of birds are not heard anymore to welcome the spring, but the human beings have also threatened their own exixtence.
