There are many things different about asexual and sexual reproduction. One thing's for sure is that asexual reproduction only involves one parent and sexual reproduction involves two parents. Asexual reproduction is not common with humans. It is used with certain animals. Sexual reproduction is how human babies are born. It usually involves sexual intercourse with the male and female. From sexual reproduction, the offspring inherits traits from both parents. I don't really think one method is better than the other because both methods are used different depending on what or who you are. For example, if you are an human, I'm pretty sure sexual reproduction is the only possible way. You can't really produce a baby on your own; that would be a little too awkward. Take a look at the chart to view the differences and similarities between the two types of reproduction.
Recently, we have dissected a frog. It was a really cool experience, and I thought it was very interesting rather than disgusting. So how does the frog dissection help me appreciate the job of a surgeon? Well, the important idea is that without surgeons, we wouldn't be able to remove things in our body that is not needed anymore, or anything that could be causing problems to any other parts of our bodies. We also wouldn't know how the inside of our bodies looks like. Surgeons are also very important because they actually know what they are doing. You wouldn't want someone who does not know what they are doing cutting your body. I think surgeons should be appreciated more due to these facts. There is a reason why we dissect and operate on other specimens: it's for practice. Without practice, modern surgeons wouldn't know what to do or expect from what they are doing. Like people say, practice makes perfect. I think the more they get use to it, the better they will be. If there weren't any practice, I think people would never want to have a surgery; most people would probably die. Again, the surgeons wouldn't know what they are doing. They would've probably learned in books, but they wouldn't have experienced the real thing.
Believe it or not, light takes a certain pathway when it reaches your eye. I mean, you can see it since you have your eyes open, but it's more complex than that. When light reaches your eyes, it has to start with the cornea first. The cornea is the outer layer of your eye. Then the light travels into the other parts of your eye. Some of the parts you may know as the pupil, lens, blind spot, nerve system, etc. Once it passes the cornea, it gets more complex. In order for you to see something, your brain has to interpret it by receiving the signal from the light. That's why the light travels into your eye through many parts. Once it passes the cornea, it then goes to your lens. After that, it goes to your pupil, then into your nerve system. Of course, your nerve system is connected to your brain. So that's when your brain is able to receive the signal and then interpret. It's not as simple as it sounds, but it happens very quickly. You don't really feel the light going through all this process.
The whole purpose of our zoo trip was to see our animal in person. Fortunately we did get to see our animal, the Fiji Banded Iguana. I was very excited to see that it was there. It wasn't difficult finding it either. Well, anyway, I knew that that was our animal because I remember its appearance from images I have seen. It looked exactly like how it looks in pictures. During my research, I learned that my animal, the Fiji Banded Iguana, has a very long tail and a short crest of scales on its spine. That's exactly what I also saw in person. I also saw that it was living in a swamp type of environment. The iguana that I seen had blues stripes on its body. I knew that it was a male because I learned that only the male iguanas have blue stripes. I'm glad I got to see my animal at the zoo because I would have been disappointed if I didn't. It's like learning about someone famous, or something famous, but in this case, it's just a simple animal I never learned about. It was like meeting a person. Nothing really surprised me when I saw my animal, nor did it change the research I did. It was exactly the animal I learned about. The reality was better in some ways than the research. The research helped me learn and find out more about my animal, but the reality gave me a good look of my animal.I definitely learned a lot from this project. The Fiji Banded Iguana is an awesome animal!
Do you know how a rainbow forms? Well, it is not that complicated to understand once you know a lot about light and reflection. Rainbows form because the object looks to be a certain color because it is only reflecting that wavelength of light, all the other wavelengths are being absorbed. Therefore, the light is reflecting from the ocean. That is why most rainbows are over oceans. It is reflected off the sun, which is why we are able to see the many colors of the rainbow. It is the colors that we see because the all the wavelengths are the same. In other words, they are made when light is refracted through millions of droplets in the air. White light is made up of red, orange, yellow, green, blue and violet light, so when it is split into components, it is seen as a rainbow.
Last week, we had to blog about our knowledge about the sky's blue appearance. This time, we have to give an exact answer. So here it is: the sky is blue because the blue wavelength from the sun is being scattered by the atmosphere more than any other color wavelength. This means that the blue wavelength is the only one that appears the most. So it doesn't mean it's the only color. The sky is blue because it is the only color that is visible to us. It is combined with other lights in white light, such as red, orange, yellow, green, violet, and indigo. Blue is the only color that is able to be scattered the most and visible to our eyes. The further you go into space, the sky does not remain blue. Imagine if the sky was the color of all the different colors in the rainbow!
I honestly don't know why the sky is blue. My lucky guess would be that it has something to do with the sun and oceans, or it has something to do with outer space. I have not learned about why the sky is blue. If I have, I think I would have remembered because it it something useful to remember. I think the sky's blueness has something to do with the sun because it is like a color thing. I think something reflects off of it which is why it is blue. I'm pretty sure it has something to deal with outer space. I have seen in movies that the higher you go up in the atmosphere, the darker it gets. So it's light blue now, but when you go higher, it gets darker. I really don't know why the sky is blue. But hopefully, I get to learn in class all about it. I think it would be interesting to learn about it because I dislike not knowing about these things. Some people are saying God painted the sky blue. I think that is true in a religious perspective.
Plant fossils can be found in Antarctica due to many reasons. I have learned in my science class that the land that we live on today wasn't always how it is now. The continents were once in one big form, and that can explain why plant fossils are found in Antarctica. It is one of the coldest places on earth and no one or anything can survive there for long. So why would there be plants there? Well, when it was once attached to all the other continents, it was probably located in an area where the climate was warm and tropical. When the Pangea broke apart, it became it's own area. Another reason why plant fossils could be found there is because Antartica use to be a land area where animals and plants use to live on due to all the sources that were avaliable. Plants could only survive when there is a lot of sun in the area, and also with water. So, Antartica had to have all those sources in order to have organisms living there.
For the zoo project, we are in a group of 4, and each person has a specific thing to research about. The four parts to this project are adaptation, reproduction, classification, and human interaction. I got the role to research about the classification and general facts of our animal, the Fiji Banded Iguana. The classification and general facts are pretty simple. The classification can be described as what species it belongs to, or what its scientific name is. Those are just examples of the classification. I found most information on wikipedia because simple information like that can be found on there. The general facts of the animal is basically the simple facts about it. Some things I had to research about was its diet, description, etc. I really enjoyed this part because it was simple and easy for me to understand. I also think it is the most important part because it's the area that really describes the animal. Without this type of information, the Fiji Banded iguana wouldn't really be known.
I think the greatest scientific discovery in history, or in this case, discoveries, has to be finding fossils. Some people may think that's not the most interesting thing ever found, but I do. Fossils have changed the way people thought about Earth in many ways. From fossils, we are able to see how Earth was like billions of years ago. It's amazing how you can learn so much just from investigating a piece of old rock. To think that there were huge extinct animals roaming around Earth is also a crazy thought. Who knew there would be any of this special, unique animals around Earth if it wasn't for fossils? Finding fossils is an on-going process. I'm pretty sure there are millions of fossils all over the world waiting to be discovered. The most commonly found fossils are of dinosaurs. Thanks to fossils, scientists can learn about all the different animals that use to live on Earth. Another thing that is also preserved from fossils are plants. These plants are usually extinct also and they show what those animals ate. There are many other things that have been found from fossils, such as insects, footprints, rocks, etc. Finding these fossils keep our mind curious which is a good thing.
