The abyssal zone is home to a number of animals such as the deep-sea anglerfish, the black swallower and the giant squid. Generally, larger creatures that are able to withstand the pressure of the ocean's depths live in the abyssal zone.
A:Early Greek astronomers named the galaxy "Via Lactea" in reference to the pale band of light formed by stars along the galactic plane. The origin of the name, which translates as "Road of Milk," has been lost to time.
A:Elliptical orbits are the paths taken by objects as they fly around a massive object, such as the sun or Earth. Such orbits are not round as is commonly supposed; instead, they orbit the massive body in the shape of an ellipse. Ellipses are like circles that have been elongated slightly, and they are also referred to as ovals.
A:The astronomical telescope is a central apparatus used to study distant planets, stars and moons from the Earth. Astronomer Galileo Galilei famously used the earliest telescopes in 1610 to prove the heliocentric solar system theory put forth by Nicolaus Copernicus in the early 16th century.
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:The Cassini Division, a gap in the rings of Saturn, is caused by gravitational pull from Saturn’s moon Mimas. The moon’s gravity affects the tiny particles that make up the rings, creating what looks like empty space. Other divisions in Saturn’s rings are the result of similar interactions with the planet’s moons.
A:The brain is important in the human body because it allows a person to think, feel and store memories, and it controls and coordinates the body’s actions and reactions, states the Atlanta Brain and Spine Care. The brain is an incredibly complex organ composed of many parts, including the cranium, the cerebrum, the brain stem and the cerebellum.
A:By maintaining homeostasis, organisms remain healthy, strong and stable, with protection from the attacks of foreign organisms, such as viruses, bacteria and fungi. Homeostasis enables organisms to remain balanced while living in constantly changing environments.
A:Algae live in bodies of water and damp places and are commonly found in both aquatic and terrestrial environments. Terrestrial algae mostly live in moist, tropical areas. They prefer wet places, because they do not have vascular tissues and the other necessary adaptations to survive on land.
A:The function of a synaptic knob is to change the action potential that is carried by axons into a chemical message. The chemical message then interacts with the recipient neuron or effector. This process is called synaptic transmission.
A:Coefficients are the numbers placed before the reactants in a chemical equation so that the number of atoms in the products on the right side of the equation are equal to the number of atoms in the reactants on the left side. If a written chemical reaction were not balanced in this manner, there would be no information available regarding the relationship between the reactants and products. Also known as stoichiometric coefficients, these numerical values demonstrate that the number of atoms on either side of the equation are equal to each other.
A:Industrial chemistry is concerned with using chemical and physical processes to transform raw materials into products that are beneficial to humanity. This includes the manufacture of basic chemicals to produce products for various industries. Industrial chemistry can be thought of as an industry that generates synthetic replacements for natural products.
A:Green and orange make brown. Per Color Matters, green and orange are both secondary colors, meaning that they are made by mixing two primary colors. Mixing any two secondary colors yields a brown shade, from muddy brown to olive brown.
A:No combination of other colors can be used to make white paint because any other color of paint absorbs some of at least one particular wavelength. Combining paints or filters to form other colors is known as subtractive color mixing.
A:When working with watercolors or similar types of dye or paint, mixing primary colors allows painters to create specific shades not included in the paint kit. Mixing blue and green paint together creates any shade of aqua desired.
A:Green is made by mixing blue and yellow. A mixture containing more blue than yellow makes dark green, while a mixture with more yellow than blue makes lime green, and a blue-and-yellow mixture with white added makes pastel green.
