A:Seeing a shooting star means that a meteor is plummeting toward earth. The glowing appearance is caused when the meteor's surface catches on fire upon entering the Earth's atmosphere. A shooting star, therefore, is not actually a star.
A:Sir Isaac Newton never married and did not have any children. According to Biography.com, the English mathematician and physicist, who was known for his law of gravitation, died on March 31, 1727, at the age of 85.
A:The atmosphere of Jupiter consists of 90 percent hydrogen gas and nearly 10 percent helium. However, its atmosphere has trace amounts of ammonia, sulfur and water vapor. Jupiter is a gas giant that is also the biggest planet in the solar system.
A:A popular solar system project idea is the construction of a solar system model. While the hanging Styrofoam ball model is an easy-to-create option, constructing the solar system in panoramic form in a shoe box can also be fun.
A:Titan is 3,200.051 miles in diameter. It the second-largest moon out of hundreds in the solar system and is Saturn's largest. Titan's mass is 80 percent greater than that of the Earth's moon, and its diameter is 50 percent longer than the diameter of the Earth's moon.
A:Galileo's main impact on the world was his improvement upon the telescope and being the first to use it in the science of astronomy. He also supported the Copernican system that stated that planets orbit the sun rather than the Earth as the Catholic Church said at the time. His other contribution was to contradict Aristotle's teachings that heavier objects fall faster than lighter ones.
A:Charles Darwin, an English scientist, wrote the book, "On the Origin of Species by Means of Natural Selection," which has served as the basis for modern theories concerning evolution since its publication in 1859. While evolutionists existed before his time, Darwin's theory of natural selection changed the way humans think about the natural world.
A:Humans, along with every other living organism, are classified as members of several groups, each nested within higher classifications. Humans are technically classed as Homo sapiens, with Homo being the genus humans belong to and sapiens as the species name.
A:The end products of fermentation are alcohol, carbon dioxide and lactic acid. The process is essential in the production of beer, fermented milk and bread. To arrive at these end products, sugars are broken down in a process called glycolysis. During the process, huge amounts of hydrogen atoms are produced and deposited on pyruvic acid, the end product of glucose.
A:Bacteria that are capable of propelling themselves forward as well as changing direction are called motile bacteria. This ability allows bacteria to flee from predators, move toward nutrients, and react to changes in their environment. Bacterial motility is important for both root colonization and chemotactic behavior and survival. When describing bacteria movement, scientists often also use the words motility and locomotion.
A:The defining characteristic of multicellular organisms is the possession of more than one cell. In order for a multicellular organism to function, its constituent cells must be capable of identifying and attaching to one another.
A:Barium phosphate is used to replicate lead contamination in soil without the accompanying lead toxicity. Because of its lack of toxicity, barium phosphate can be utilized in soil as remediation of metal.
A:Solder alloys are made from a mixture of tin, lead, brass and silver. Solder made from tin and lead has a lower melting point, while brass and silver are used to create an alloy able to withstand higher temperatures.
A:Whistling fireworks require two components: an explosive mixture that makes a sound when it burns and an empty portion of the rocket tube to act as a resonance chamber. The gas released creates the noise, while the chamber allows the sound waves to build on each other to earsplitting volume.
A:The primary difference between liquids and gases is that the constituent molecules of liquids are closer together and move less than those that make up gases. Liquids and gases behave in a number of similar ways, although both differ greatly from solids.
A:The basic color combination that makes purple or violet is blue and red. Blue and red are primary colors. However, to get a violet or purple color that is not muddy looking, one needs the right types of blue and red colors.
A:Gray is made by mixing black and white. While black and white are technically not colors – black is a shade, while white is a tint – mixing the two in equal amounts yields a medium gray. No two pure colors can be mixed to make gray.
