We're Not Twin.

Assalamualaikum and hi. I don't think this will be a long post since I'm busy.. First of all, I want you to look a picture below..

look at the faces properly.

Does we look same? No, right? I and Rina was walking to the lab since it was science. On our way, we saw Sir Rahim and a girl.. Then the girl asked Sir Rahim "are they twins?" Then, both of us laugh.. :)

Want to know about twin?? Let see,, TWIN is one of two offspring produced in the same pregnancy. Twins can be either identical and fraternal. Identical means that they develop from one zygote that splits and forms two embryos. While fraternal develop from two separate eggs that are fertilized by two different sperm. Identical sperm also known as monozygotic but fraternal known as dizgotic. 

Half-identical or semi-identical twins or also known as half twins are the result of a very rare form of twinning which the twin inherit exactly the same genes from their mom but different genes from their dad. Though examples of half-identical twins have been found, the exact mechanism of their concept is not well-understood, but could theoretically occur in polar body twinning where sperm cells fertilize both the ovum and the second polar body. This situation is not the same as the common form of fraternal twinning, in which two genetically different avum are fertilized by two genetically different sperm. In this case, the ovum are genetically identical.

I think thats all and my conclusion is we are twin from different sperm and ovum. :)

Assalamualaikum and bye.

The Hobby Of Collecting.

Assalamualaikum and hi.
This lovely day I(Ayu) want to post about the hobby of collecting.

Hobby is an activity a person does during his or her pastime. There are many types of hobby. For example, there are some people make collecting things as their hobby.

There are various type of collecting, such as collecting stamps. Some people love to collect stamps because they can learn about other country culture, flowers and national anthem. Collecting stamps only take small cost to buy them compare to collect dolls or robots which cost you an arm and a leg. Another example is collecting books. People collect books because they can gain knowledge from it. By doing this activity, teenagers will not involve in negative activities like playing computer games that doesn't bring any benefit for students. There are many types of book that teenager can collect. For example, storybooks, comics, novels, revision books and so on.

An example for expensive hobby is collecting dolls and robots. People collect dolls or robots because they love to play with it, but some people like to collect dolls because they think the dolls are cute. Most people that collect dolls and robots are categories as rich people.

Teenager must have their own hobby to avoid from being involve in negative activities. Teenagers can also be profitable. They can sell the stuff that they collect and make money from it.

I think that all about the hobby of collecting. I hope you guys enjoy reading these since I made it myself.
That it from me, Assalamualaikum and have a nice day.

Rainbow.

Assalamualaikum and hi.
This lovely day I've updated My Blog. So, I want to continue updating.
Today I want to share with you about RAINBOW.
I bet all of you has seen a rainbow before, right?
Before I enter school's gate, me and my friend Rina saw a rainbow.
So, I think to share about it today.

Rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky when the sun shines on to droplets of moisture in the Earth's atmospehere. It takes the form of a multicoloured arc. Rainbow caused by sunlight always appear in the section of sky directly opposite the sun.
In a primary rainbow, the arc shows red on the outer part, and violet on the inner side. This rainbow is caused by light being refracted while entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.
In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, red facing the other one, in both rainbow. This rainbow is caused by light reflecting twicw inside water droplets. the region between a double rainbow is dark, and is known as 'Alexander's Band" or "Alexander's Dark Band".
These are examples of rainbow,

A Double Rainbow

A Supernumerary Rainbow

Reflection Rainbow and Normal Rainbow 

A Red Monochrome Rainbow

A rainbow spans a continuous spectrum of colour. There are no bands. The appearent discreteness is an artefact of the photopigments in the human eye and of the neutral processing of our photoreceptor outputs in the brain. Because the peak response of human colour receptors varies from person to person, different individuals will see slightly different colours, and person with colour blindness will see a smaller set of everywhere, with normal colour vision. 

That all for this day. Read more about Rainbow HERE

I hope you guys understand this post and do leave your comment.

Assalamualaikum and good night.
