NASAs space shuttle fleet was comprised of orbiters Atlantis, Challenger, Columbia, Discovery, Endeavour and a prototype craft named Enterprise.The space shuttle program began in 1981 and conducted 135 missions.

Stars on the main sequence that are the same size as the Sun begin as yellow stars and turn into red giants as their hydrogen fuel runs out. Other stars shrink or explode, depending on their size.

Natural objects found outside of the Earths atmosphere, such as planets, stars, moons, comets, meteors and asteroids, are some of the heavenly bodies in space. It is believed that there are other forms of heavenly bodies or objects in space that are yet to be discovered and explored.

Four layers of the earths atmosphere containing various gases make up the composition of the sky. The layers of the atmosphere are divided into the troposphere, the stratosphere, the mesosphere and the thermosphere. The atmospheres divisions occur according to temperature fluctuations.

Galileos 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 Aristotles teachings that heavier objects fall faster than lighter ones.

Tasco provides free online instruction manuals for all of their products. Their telescopes come partially assembled. The tripod needs to be assembled, then the main body of the telescope attached to it. Once the main body of the telescope is on the tripod, the various accessories such as finderscopes and eyepieces need to be attached. The accessories vary slightly by model of telescope.

The sky ends at the Karman line, which is located at about 67 miles above sea level. Above this line, space begins. However, technically, the sky does not end so much as the atmosphere, or sky, thins until there is no oxygen left.

In biology, plants are the most popular examples of producers. Other examples include algae, seaweed, phytoplankton and some bacteria are also producers. Good examples include cyanobacteria and green and purple sulfur bacteria.

What Is an Example of Parasitism in Coral Reefs?

One example of a parasitic relationship in coral reefs includes crustaceans from the Copepoda or Isopoda orders, which attach to fish in the reefs, sometimes causing harm but at other times simply holding on and feeding on food particles that float by them. Coral reefs feature organisms that coexist in a number of different relationships, including parasitism, but also symbiosis, competition, commensalism and mutualism.

The volvox primarily eats through photosynthesis. Individual cells within the organism contain a red eyespot and, along with chloroplasts, make food from sunlight.

What Are the Abiotic Factors of a Forest?

The abiotic factors present in a forest include precipitation, soil chemistry, temperature, water chemistry, sunlight and moisture level. All these factors have an affect on the living things in the forest ecosystem.

What Are the Eight Levels of Biological Classification?

The eight levels of biological classification are domain, kingdom, phylum, class, order, family, genus and species. These levels are an important part of taxonomy, which is the science of identifying species and organizing them according to systems of classification.

What Is the Importance of Photosynthesis in Life?

Photosynthesis is the process that drives nearly all of the energy economies on Earth. It is the mechanism by which plants and green algae do the work of converting sunlight into an effective fuel for driving protein and carbohydrate synthesis. These biomolecules are then used by the plant for its own growth and reproduction.

Diffusion is the movement of something from where there is a lot of it to where there is less. For example, if someone is baking cookies, that pleasant smell shows up near the stove first. Little by little, it spreads throughout the whole room. The molecules with the cookie aroma diffuse, moving from around the stove to other areas.

The word lithium is derived from the Greek word for stone, lithos, because it was first discovered in stone. Lithium is one of several alkali metals discovered and named in the early 1800s. The other two, sodium and potassium were also named after the materials that were being studied when they were discovered.

What Is the Use of Chloroxylenol in Dettol Antiseptic Liquid?

The chloroxylenol in Dettol is an antimicrobial disinfectant used to kill bacteria and to prevent infections on minor scrapes, cuts or burns. The substance is commonly found in antibacterial soaps, but it is also used to control bacteria, algae and fungi on industrial surfaces where clean facilities are needed. Some liquids that contain chloroxylenol must be diluted before application on the human body.

Gas comes from crude oil. The remains of organisms that lived on Earth hundreds of millions of years ago were eventually covered with sediment and rock. The pressure and heat of the Earth caused the remains and sediment to combine and create liquid hydrocarbon, or crude oil.

According to WebMD, iodine is commonly used to prevent iodine deficiency and disinfect wounds. It can also be used to protect against radiation, treat ulcers and purify water.

How Does a Firefighter Use Chemistry?

Firefighters need a strong understanding of chemistry for personal and public safety, to enhance the effectiveness of their efforts and to prevent adding to the many hazards present during a fire. A firefighter uses his or her understanding of the chemistry of building materials and furnishings as well as the interaction of suppression chemicals with fire.

What Does the Color Mauve Look Like?

Mauve is a pale bluish purple. Compared to a pale magenta, mauve is a more grey and more blue color. It is often described as a pale violet.

What Term Describes the Lightness or Darkness of a Color?

Value is the term that describes the lightness or darkness of a color. The value of a color helps to define a form and to create the illusion of depth in an image.

What Is the Complementary Color for Gray?

Gray is considered neutral and is complementary with any other color. Gray functions in a way that is similar to black and white when it comes to complementing other colors.

Since maroon is opposite yellowish green on the color wheel, those colors go well together. However, there are other ways to use the color wheel to determine matching colors. For instance, an equilateral triangle connects colors that complement each other, so maroon harmonizes with blue-green or orange-yellow.

Refracting prisms take advantage of the fact that light makes changes in direction when passing from one material to another, but that different wavelengths bend different amounts. Thus, prisms can split white light, which is actually light made up of multiple wavelengths, coming in at one angle into its constituent colors going out at different angles. They can also do the opposite, condensing multiple color rays into one white ray.

Indigo is made by combining blue and red. This color always falls between blue and violet on the color spectrum.
