Antibiotics



Personally, I don't think that Antibiotic Use Should be Restricted. I think it's very useful. In 1940s, Antibiotics was first used and the antibiotics are one of the great advances in medicine. the two major types of germs are bacteria and viruses. Antibiotics are effective against bacteria because they work to kill the living organisms by stopping their growth and reproduction. But viruses do not respond to antibiotics at all. People like to use the antibiotics for colds or viral illnesses, but it won't work! Not only that, it has a dangerous side effect. Overtime, this will help create bacteria that have become more of challenge to kill!

We can see how dangerous it is, but... I still think that the Antibiotics should not be restricted because when I research about this, I see that the only problem is people use it in the wrong way, it people do it right, this won't happen. People should treat only bacterial infections. There are ways that people can take Antibiotics safely, it's not so dangerous, if you know how to use it in the right way. 'Treat only bacterial infections and ask for advices from the doctors.'

Snowy Owl


In the summer, snowy owls are brownish with dark spots and stripes. In the winter, they are completely white.


Scientific name (Genus & Species): Bubo scandiacus


Habitat: Range; Northern most Canada, Alaska, also circumpolar

     Summer      Winter


Environment: open spaces; tundra, grasslands, or frozen lakes.



Description: 

The feathers of the snowy owl have no pigment. This leaves more space for air which helps to keep the owl warmer because air is such a good insulator and it also makes the owl white.  

One of the biggest owls is up to 27 inches.

Wingspan is about 45-60 inches.

They hunt silently, hunt during the day unlike most owls.
Breeding once is about 8-10 eggs, eggs are laid on the ground or on hummocks because there aren't trees in the Arctic.



     Reason why I like it:

     First, I am interested in it and start researching this owl because I think it’s beautiful and strange because it doesn’t live in Thailand. It is in the cold country and has snow. I see it from the movie (Harry Potter). When I researched this kind of owl, I found this owl is different from others. The usual owls hunt at night but these snowy owls hunt during the day. They all have the strange bright yellow eyes. Their skins are as white as the snow. I think that this kind of owl is not like an owl. It looks like a normal bird.

My Favorite Science Quote ☆

Science is the desire to know causes.
          William Hazlitt (1778-1830) English essayist.
          In my opinion, this phase is correct. 'Science is the desire to know causes.' means that the thing that all the scientists firstly do is asking questions; why this or that happen, how this or that happen, and then they start to do the experiments.
