What structure makes the windpipe stay open but able to bend?

The windpipe is also known as the trachea. InnerBody states that it goes from the bronchi to the throat, just under the larynx. In the average person, it is about 4 inches long and around 1 inch in diameter. The inside of the trachea is lined with mucosa, which is smooth, moist tissue. The structure of the windpipe allows the individual to continue breathing effortlessly whilst bending and moving her neck.

What is the chemical formula for hydrogen gas?

Hydrogen is the simplest chemical and the first element in the periodic table of elements. The atom of its most common isotope is composed of one proton and one electron. Hydrogen is also the most abundant element in the universe and the main constituent of stars. Inside the stars, hydrogen atoms are fused together to produce helium.

What is GMT?

GMT is also sometimes referred to as UTC, or Coordinated Universal Time, but the two are slightly different. In 1884, at the Washington Meridian Conference, GMT was adopted as the standard for calculating time all over the world. Universal Time and the idea of 24-hour time zone systems grew from GMT. When the sun is exactly overhead at the Prime Meridian, it is 12:00 noon at Greenwich, England.

What are thermal binoculars?

Thermography works by detecting infrared radiation, which is a result of body heat. It produces images of the objects viewed and distinguishes them from each other by heat level, allowing a building to be viewed distinctly from the street in total darkness because their heat levels are different. Warm objects such as animals and humans are easiest to see with thermal vision.

What is the life cycle of a coconut tree?

Coconuts are an important fruit in many parts of the world, though humans are one of the few species that can actually make use of them. The heavy fruits are known as drupes, which are a group of fruits that includes species such as plums and peaches. Drupes have a hard seed pod surrounded by a mass of softer tissue. The fruit of a coconut is extremely fibrous and very tough. Its structure protects it from hungry animals as well as protects the embryo on long ocean journeys, keeping out salt water and preserving the seed for up to three months at sea.\nResearch suggests that coconuts first app..

What are the high and low temperatures on Saturn?

The reason for these differences in temperature is that Saturn receives little to no heat from the sun. Instead, the majority of the planet's heat radiates out from within its core. Saturn has a horizontal temperature gradient, as opposed to Earth's vertical gradient. The horizontal gradient also means that there is only a minor temperature difference between Saturn's equator and poles.

What do you call movement of a molecule against a concentration gradient?

Animal cells maintain an ion concentration gradient by use of active transport. During active transport, the cell pumps two potassium ions into the cell, while pushing three sodium ions out. When the cell receives a signal, the active transport stops and the ions begin to move with the gradient. In nerve cells, active transport occurs until the nerve must send an impulse. When the active transport pump stops, rapid diffusion allows the impulse to occur almost instantly.

Does acrylic shrink?

Acrylic is a man-made fabric that shrinks when it is washed and then placed directly into a hot dryer. The shrinkage is minimal compared to other kinds of fabric, like cotton and cashmere, but the effect is still prominent enough to change the size of a garment. Washing in cold water and drying on low heat helps preserve the shape and durability of acrylic clothing. Hanging clothes to dry is the best way to avoid acrylic shrinkage and preserve the shape and color of clothes.

How are felsic, intermediate and mafic igneous rocks different?

Igneous rocks are formed by the cooling and crystallization of magma. The temperature of cooling determines which types of minerals are found in the rock and helps scientists classify the rock as felsic, intermediate or mafic. Rocks that begin their cooling at low temperatures are rich in minerals containing silicon, potassium and aluminum. High temperature igneous rocks contain minerals higher in calcium, sodium, iron and magnesium. Ultramafic rocks are a fourth classification of igneous rock. These rocks are rare on the Earth's surface and contain low amounts of silica the minerals oliv..

What is 44 centimeters in inches?

The conversion factor is 2.54 centimeters per inch. The centimeter is a unit of measurement that is a part of the metric system. The metric system is the standard system used to measure length in many countries, though inches are used in the United States instead. Even though efforts have been made to get the United States to adopt the metric system as the new standard, the English system of inches persists. A caveat to this is found in certain fields of work in the United States, such as the medical field.
