The Sun

UVB’s 1. The sun shines on the skin. 2. The UVB light interfaces with a form of cholesterol in the skin called 97-dehydrocholesterol. 3. This is synthesized into pre-vitamin D3, which is immediately converted into vitamin D3. 30 minutes of midday sun in a bathing suit, and you’ve absorbed up to 20,000 IU of vitamin D. Whether you spend half an hour in the midday sun or take 2 10,000 IU of vitamin D3 in tablets, it’s then transported to the liver where it’s turned into D25 for storage. These…

1. How is the Moon dependent on the Sun? The Moon is dependent on the Sun for its different lunar phases. Although these phases may not be essential to the existence of the Moon, they would not occur without the Sun. Neither a lunar nor a solar eclipses would be possible without the Sun, again. Also, although this is not a direct dependence upon the Sun, if the Sun did not give the Earth an object to orbit, the Moon may never have fallen into orbit with the Earth. 2. How are seasons created?…

stating that, “ …the orbits of the planets around the sun were not circular, but elliptical, with the sun at one focus of the ellipse rather than at the center.” According to the Ptolemaic Theory and Aristotle, the planets moved in the most perfect circular and uniform motion. However, Johannes Kepler argued that the planets do not orbit in circles, but in ellipses. His second law demonstrated that the speed of a planet is greater when closer to the sun and decreases the farther it is from it.…

In general, Fritz Scholder used people to show ethnic subject matter. This does not coincide with what I have learned about earlier painters such as those in the Oklahoma School. The most artwork from earlier painters are traditional portraits and pictures of recording the ceremony. Fritz Scholder combined Indian culture with American culture to show the Indian with a beer can, the Indian with a American flag, and a portrait of himself with a cat. He also drew abstract in which expressed…

Constructed around 350 B.C., Chankillo is believed to have been built for seasonal events, rituals, sun festivals and for keeping a seasonal calendar through solar observations (Ghezzi, Portal to the Heritage of Astronomy 59-61). Chankillo is known as the Peruvian ‘Stonehenge’ as stated by the MIT Technology Review. It has 13 towers that are neatly aligned…

recently just moved to the planet Venus, from Earth, where the sun shines for one hour every seven years. Margot misses seeing the sun everyday from her house in Ohio. Instead, everyday, she sees rain just pouring down and never stops. But Margot is not the only kid missing out on the sun. Other kids on Venus, who were born there, have never seen the sun or even remember what it looks like. Everytime Margot tries to tell them about the sun, they fill themselves with jealousy and they ignore her.…

case she was called lying, but then had fun talking about the sun. In the story, Margot is a news girl adapting to the Venus structure. Since she’s been there it's been nothing but tough roads and windy turns. During her school hours, they make poems and sing about the sun. her poem was read aloud and everyone thought she was lying about the sun. Then again the other kids have never seen the sun. So with everything she did about the sun, they intentionally said mean bad things to her. Soon…

include the fusion of He4 and the carbon nitrogen cycle, which both are elaborated. These processes vary in percentage from star type but occur in every type of main sequence star. I. Introduction & History The sun, a landmark that has been shining through all of the…

seeds as soon as they last 10 seconds inside the microwave. This can be a good project for others it looks preety cool, it can be used in the REAL WORLD. There are people who plant these Radish Seeds and put them in the ground were it can get enough sun and they can water the seeds. The seeds can grow and can make a business with foods and become salesman. The topic i chose is in Biology, and my topic is about Radianting Radish Seeds inside a microwave. Radiating means heat in the form of…

orbital periods are in resonance with Neptune (or at least very close) meaning that the number of times the object orbits the sun, and the number of times Neptune orbits the sun are tidy ratios such as 2:1, 3:2 and several others. Objects at a particular resonance all orbit at about the same average distance from the sun. Pluto, for example, averages about 39.4 AU from the sun and is in 3:2 resonance with Neptune. This means for every two orbits made by Neptune, Pluto makes three. Those with 3:2…
