What is the name of the muscle that extends the elbow?

The triceps brachii muscle is located behind the upper arm. It extends the arm and holds the elbow still when necessary. The much smaller and triangular anconeus muscle helps the muscle extend and rotates the forearm; however, the elbow relies on the triceps brachii and not the anconeus. Because of this, the anconeus is considered part of the triceps brachii by some.

How big is a tornado?

The National Weather Service Weather Forecast Office reports that the path of a tornado can last from just a few yards to over 100 miles depending on numerous simultaneous weather factors. The average tornado has a damage path of 1 or 2 miles and a width of around 50 yards. It is important to remember that the size of a tornado is not necessarily an indication of its strength, as large tornadoes can be relatively weak, and smaller ones could be violent.

What happens when the corpus callosum is cut?

Also known as split brain surgery, the corpus callosotomy is only performed in patients with extreme and uncontrollable seizure disorders that affect both sides of the brain, according to WebMD. Patients who suffer from drop attacks, which are serious seizures that cause the patient to suddenly fall and potentially suffer serious injury, are sometimes considered for this procedure if anti-seizure medications have not proven effective.\nAccording to About Kids Health, cutting the corpus callosum can cause unwanted side effects in many patients. Language and visual identification are handled by ..

Can a plant survive without sunlight?

Plants need sunlight or another form of light in a similar portion of the electromagnetic spectrum, because they convert light energy along with water and carbon dioxide during photosynthesis into chemical energy in the form of glucose. They can survive in darkness for short periods of time using these sugars in a manner analogous to a human surviving without food by subsisting on fat stores.

What are the major causes of thermal pollution?

Industrial processes that use water as a cooling agent are most likely to cause thermal pollution. Factories sometimes use water from lakes or streams to cycle through the plant and reduce the temperature of machinery. The heat given off by the machinery is absorbed by the water, raising the overall temperature of the body of water when it is pumped back into the river or lake.\nThe contributions of deforestation and urbanization to thermal pollution are smaller than that of industrial processes, but they are still significant. When trees are removed from the shoreline, more sunlight reaches t..

What is 186 centimeters in feet?

Centimeters are units of length in the metric system, which is used throughout most of the world and in most scientific contexts. Feet and inches are units of length in the imperial system of measurement, which is used officially in the United States and Canada and unofficially in much of the United Kingdom.

How many sides does a snowflake have?

Though it's said that no two snowflakes are alike, this is a false truism from the perspective that all snowflakes have six sides. In this way, all snowflakes are actually very much alike, though the way each individual snowflake's crystalline structure manifests will be somewhat different from all others. Snowflakes build up bit by bit in a process of freezing water molecules gathering together around strongly negative and positive charged particles, leading to the growth of a three-dimensional, six-sided flake. Changes in atmospheric temperature and humidity as the snowflake moves ..

How long does it take for aluminum to decompose?

Many other items are made from aluminum, all of which are recyclable. Aluminum products include house siding, roofing materials, gutters, some lawn furniture, car parts, framing, soup cans and some electronic components. Metro Recycling states that it takes 1/20 of the energy to recycle aluminum products as it does to smelt aluminum from scratch.

How many blocks are there in 1 mile?

Most cities blocks are square grids, meaning that their length and width measurements are the same. In this case, it would only be necessary to know the number of feet on which the grid is based. City blocks can range from 200 all the way to 900 feet on one side. There are 5,280 feet in a mile. So to find out how many city blocks would equal a mile, simply divide 5,280 feet by the number of feet in a block in any given city. In Tucson, Ariz., for example, blocks are 400 feet long. So 13.2 blocks would equal 1 mile.

How far is the constellation Gemini from Earth?

The brightest star in Gemini, Pollux, is 34 light years away from Earth. Castor, the second brightest star in the constellation, is 52 light years from Earth. Other major stars in Gemini include Alhena at 105 light years from Earth, Wasat at 59 light years from Earth, Mebsuta, which is 900 light years from Earth and the double star Mekbuda, which is 1200 light years away from Earth. Eta Gem is a double-star that is 350 light years away, while Kappa Gem, a yellow giant, is 143 light years away.
