The Omega Meme!!

I’ve tagged students for the Omega Meme!

The rules are as follows:

Each player answers the six questions posted on this blog.

The rules of the game are posted at the beginning before those answers are listed.At the end of the post, the player then tags 8 people and posts their blog names, then goes to their blogs and leaves them a comment, letting them know that they have been tagged and asking them to read your blog.

Then follow the instructions about adding a page element at omegascience.blogspot.com.

1. My favorite TV show is Gossip Girl because you can relate to it.

2. My favorite meal is pizza because it's yummy. What's not to love?

3. My favorite nonschool activity is hanging out with my friends because they help me forget about the hard things in life.

4. Someone I look up to are my parents because they always head me in the right direction.

5. My goal for the future is succeed in life and have a wonderful job.

6. In the first hour after school I usually do my homework, go on the computer or hang out with my friends.

Newton's Laws

Sir Issac Newton formed three laws using observations of the world around him, called Newton's Laws. His three laws explain rest, constant motion, accelerated motion, and describe how balanced and unbalanced forces act to cause these states of motion. Newton's first law is often termed "Law of Inertia." His first law states if an object is at rest will remain at rest and an object in motion will remain in motion unless external force is applied to it. For example, if you slam suddenly on the brakes of a car, you will jerk forward or move your body forward. If you're not wearing a seatbelt, you could go flying through the windshield! Sir Issac Newton's second law states the relationship between force, mass and acceleration, F = MA or force = mass x acceleration meaning, the force of an object is equal to its mass times its acceleration. For instance, who would have the largest impact, on the bed, if a 265 pound person (M1) and a 128 pound person (M2) both jumped at the same accelertion (A) and landed on the mattress? The 265 pound person would make a larger dent (F1) than the 128 pound person (F2) because 265 pound person is heavier and has more mass, therefore, producing a greater amount of force. Lastly, Newton's third law states for every action there is an equal and opposite reaction. For example, you shoot a gun, the bullet will go forward, but the force that makes the bullet shoot out, causes you to feel a "kick" backward.

Three interesting facts that I learned are:

1) Newton's first law is often termed "Law of Inertia."

2) Sir Issac Newton's laws weren't as famous as they are today.

3) Sir Issac Newton's work is considered to be one of the most important contribution to science.

2,700 year old fabric.

Have you ever heard of a piece of fabric that was older than 2,000 years old? In Athens, Greece, archaeologists found a piece of fabric that was 2,700 years old! The material was in a copper urn. Besides the fabric inside the urn, archaeologists also found dried pomegranates. This old antique was found in a burial they think imitated the cremation of soldiers described in Homer's "Iliad."

Interesting facts that I learned was:

1) The fabric found in the urn was an organic material and easily decomposable.

2) The pomergrates, that were also found inside the urn, were offerings that linked with the ancient gods of the underworld.

3) Only a few artifacts, similar, have beein found in Greece.

In my opinion, this is extremely fasinating that several artifacts have been found from a long period ago and are shown in museums for us to see.

Tainted food.

In Washington, the government reported Thursday, that several hundred of the 6,000 hogs have eaten tainted feed. The risk of human health may be very low. The government told three states that were involved, that the meat wasn't allowed to be sold from the hogs that had eaten the feed. The Agriculture Department concluded that the three states, New York, California and South Carolina, had no more than 345 hogs that ate the food. Most of the hogs that ate the feed are still on the farms that they were raised.

Three interesting facts that I learned were:

1) Some food could not be sold so they were fed to the hog farms.

2) Since mid-March, pet food companies have had more than 100 brands of dog and cat food and treats that were tainted.

3) The pet food sent to the farms was discovered to have an ingredient, rice protein concentrate, imported from China that was tainted by an industrial chemical, melamine.

I think that food shouldn't be given to farm animals if it isn't sold in the store. Then if people eat the meat from the animal, humans will become sick or will die.

Largest coral die-off

You may hear of people being killed from natural causes, but this earthquake, which happened two years ago, in Jakarta, Indonesia caused the largest coral die-off ever documented. The scientists from the U.S.-based Wildlife Conservation Society and the government-backed Australian Research Council Center of Excellence for Coral Reef Studies, studied the product of the earthquake. Because of this earthquake, it caused the corals to have the largest die-off ever documented.

This problem can relate to science and life because the earthquake caused several people to die and the largest coral die-off.

In my opinion, the earthquake caused countless people to die and also caused the largest coral die-off. Even tough most of the coral had died, the scientist concluded that the coral would eventually grow back in several years to come. Because of this natural disaster, it took away the lives of several people, but the people in Indonesia couldn’t have predicted or done anything to help other’s death.

The Sun

You may think that the sun is a small part of our lives, but you are wrong. The sun is has an enormous impact in our habitat. Not only is this giant star used for heat, it is also used to keep all the organisms on the Earth alive. With the sun giving off so much energy, it helps to grow food for all living creatures on the planet.

Three interesting facts that I learned are:

1) The sun has a spectral glass of G2V. "G2" means that it has a surface temperature of approximately 5,500 K, giving it a white color, which causes the sun to appear yellow.

2) The sun completes one revolution in about 225-250 million years.

3) The Sun is about 4.5 billion years old. Since its birth it has used up about half of the hydrogen in its core. It will "live" for about another 5 billion years.

I think that the sun is the most important object for the Earth. It helps the organsims on the planet to get food and other supplies that help them stay alive. I also believe that this giant star can harm the Earth.

Meiosis

Meiosis is the process of cell division where sex cells are produced, also when chromosomes split and form sex cells in the end. The male sex cell is called sperm and the female sex cell is called an egg. This division occurs in all eukaryotes. There are three basic steps:
1) the chromosome doubles
2) the 1st division
3) the 2nd division

Here’s an example of meiosis. A human body cell has 46 chromosomes. Female:

/ \

46 46

/ \ / \

23 23 23 23

I \ I /

1 egg & 3 polar bodies

or

\ I I /

4 sperm

Interesting facts that I learned were:

1) There are four stages in a nuclear division: prophase, metaphase, anaphase, and telophase.
2) Meiosis comes from the Greek work meioun, which means “to make smaller.”
3) Some eukaryotes lost the ability to carry out meiosis and got the ability to reproduce by parthenogensis.

In my opinion, I think that meiosis is an important part of life. Without the process of meiosis, any living organism wouldn't be able to reproduce. If our parents didn't reproduce, we all wouldn't be here today.
