How do you get rid of staghorn algae?

Manually remove the algae strandsWearing a pair of rubber gloves, remove the top of the aquarium, and gently pull the algae strands out of the water. Scrape up short strands with an old toothbrush. Touch the strands with the bristles, and twirl the handle of the toothbrush to embed the algae in the brush. Prepare a bleach solutionCombine five parts warm tap water and two parts bleach in a clean bucket. Remove the aquarium's plants one at a time, submerge them in the bucket for five seconds and return them to the tank. After bleaching the plants, dunk the aquarium's decorations and fi..

What uses heat energy?

Heat energy is frequently used to supply homes and office buildings, and is used by several machines such as heat engines and heat pumps. The amount of heat energy used by households and commercial offices varies, and depends on several factors, such as the outside air temperature. In these structures, heat is used to heat entire rooms, as well as power ovens and furnaces. \n\nHeat can be felt when energy is released, which is why a car engine is hot and a person feels warmer after exercising. In heat pumps and heat engines, heat is generated through the process of combustion which in turn pro..

How much is 500 ml?

The liter is the basic unit of volume in the metric system; it can be subdivided into 1,000 milliliters. Each milliliter is 1 cubic centimeter; the figure of 7.937 above is calculated by taking the cube root of 500. For those used to the American measurement system, a liter is just about 6 percent larger than a quart, while for those in the United Kingdom, an Imperial quart is approximately 14 percent larger than a liter.

What is the element fluorine classified as in the periodic table?

Fluorine is extremely reactive and cannot be chemically separated from a compound.\nThe name fluorine originates from "fluere," the Latin and French word for "flow."\nThere are total of five elements in the halogen group. The other elements included are chlorine, bromine, iodine and astatine. These five elements exist in different states of matter at room temperature. Iodine and astatine exist as solids; bromine is in the liquid state; and fluorine and chlorine are in a gaseous state.

How many chromosomes does a lion have?

The lion is classified under kingdom animalia, phylum chordata, class mammalia, order carnivora, family felidae and species panthera leo. The two subspecies of panthera leo are commonly known as the African lion and the Asian lion, with only minor genetic distinctions between the two. Due to the relatively recent diversification of many species, which only occurred 10 to 15 million years ago, scientists have encountered some difficulty in determining the evolutionary process of the felidae, or cat family. The family's karyotype, which pertains to the appearance and number of chromosomes w..

What is tropical climate?

Tropical regions of the world are located between the Tropic of Cancer and the Tropic of Capricorn. There are three types of tropical zones: tropical rainforest, tropical monsoon and tropical wet and dry. Temperatures in a rainforest remain consistent year-round, and there is usually a daily afternoon shower. A tropical monsoon climate is similar, although one or two months are drier. Tropical wet and dry territories have specific rainy and non-rainy seasons. The dry season lasts for more than two months.

What muscles are used when shooting a basketball?

When shooting a basketball, the muscles of the arm are the muscles primarily relied upon. The triceps extend the elbow during the shooting process, while the biceps help flex the elbow and return it to normal position after shooting. To grasp and let go of the basketball, the wrist extensors are used to open and close the fingers. The trapezius, which is located at the collar bone, and the deltoids, which surround the shoulder joint, help raise the arms and rotate shoulders for proper aiming and shooting.\nLocated in the chest, the pectoral muscles consist of two groups: the pectoris major and..

Is phosphorus a metal?

White phosphorous is man-made for industrial use. It glows in the dark and combusts when it is exposed to air. White phosphorous can also look yellowish, but retains the same properties. Red phosphorous can also vary in color, ranging from orange to purple. Black phosphorous is manufactured for use in the creation of safety matches, incendiary shells, fertilizers and pyrotechnics. Black phosphorous is also widely used to prevent corrosion of metal surfaces.

What is buoyancy?

Buoyancy is also highly related to Archimedes' principle, which states that the buoyancy force is the same as the force that the displaced water, or other liquid, could exert. The volume of displaced water is also the same as the volume of the object that is submerged. If buoyancy is greater than downward forces like gravity, the object will rise or float.

How is sound created?

Sound is a mechanical disturbance that propagates through some medium, such as air or water. Even vibrations that are not audible to the human ear, such as those that come from dog whistles or sonar equipment, fall into the classification of sound.\nA sound source, whether it is a diaphragm or a guitar, produces vibrations in the surrounding medium (air, liquid or solid). These vibrations propagate away from the source and form a sound wave (sound waves can be longitudinal or transverse). The medium can reflect, refract or attenuate the sound wave. Pressure within the medium, motion of the med..
