What are the simplest carbohydrates called?

There are three main groups of carbohydrates. Monosaccharides are the shortest and simplest, and are the building blocks of more complex carbohydrates. Disaaccharides consist of precisely two monosaccharides bonded together covalently, typically at the end. Finally, polysaccharides are the most complex carbohydrates, consisting of three or more monosaccharides bonded together. Common examples of polysaccharides are starch and glycogen.

What is electrical force?

Static electric forces are relatively easy to observe in action. For instance, conventional foam or packing peanuts tend to stick to hands and other objects. This is due to a charge in the surface of the peanut, which is attracted to the opposite charges in hands or other objects. Similarly, removing a wool hat can cause hair to stand on end. As the hat rubs the hair, it picks up an electrical charge; this also leaves each hair with a charge. Because the hairs have like charges, they try to move away from one another, and stand on end.\nElectric forces and magnetic forces are both products of ..

What is the purpose of body chills?

In most cases, the only required treatment is an anti-pyretic medication such as Tylenol to control the elevation of temperature, along with fluids to maintain hydration, as an elevated temperature can drain the body of moisture more quickly. However, if the fever has accompanying symptoms such as a rash, a headache, joint swelling, abdominal pains, severe fatigue, neck stiffness or shortness of breath, it is time to seek medical attention. People with a high fever (over 101 degrees Fahrenheit in the case of an infant) should visit the doctor immediately, as should anyone with a fever lasting ..

Where is a detailed image of the pancreas found online?

Site visitors to UCHospitals.edu.can access information about the anatomy of the pancreas, the exocrine and endocrine glands that are found in the pancreas, and the organ’s function.\nThe pancreas is a tapered and elongated organ that runs across the back of the abdomen behind the stomach. The widest part of the pancreas is its right side -- also known as the head. The left side, also called the body, is tapered and extends upward, ending near the spleen.

What is a vascular shunt?

Extreme vascular injury results in hemorrhaging, restriction of blood flow or other life-threatening injury. A vascular shunt allows the condition of the blood vessel to improve while awaiting surgical repair. Vascular shunting is widely used in age-related vascular constrictions resulting in vascular disease, says TechLink. The U.S. Air Force has devised a variation that allows this procedure to be performed during military maneuvers and on severe injuries suffered by soldiers and civilians.

Why does your stomach growl?

As a person digests solid food, muscle contractions help to move the food along the digestive tract while mixing it with the juices that help to break it down. Along the way, pockets of air can sometimes get trapped and moved, and as they are squeezed, these air pockets make the sounds interpreted as growling or rumbling. In addition, the stomach begins the process of peristalsis when it has already been emptied as a means to digest any remaining food that might have been missed and stimulate the nerves in the stomach that signal hunger.

What is a homogeneous substance?

An example of a homogeneous mixture is salt water in which the salt has completely dissolved. In this case, no matter how small an amount of the salt water is taken, the basic composition and appearance of the salt water remain uniform. In contrast, oil in water is a heterogeneous, or nonhomogeneous, mixture. In this case, it is possible to see clear phase boundaries between droplets of oil and the surrounding water.

What common items weigh 1 ounce?

The U.S. weights and measures relate to the British imperial system that dates to the Romans and Anglo Saxons. However, before adopting the metric system, Great Britain redefined many of the units in 1824, while the United States retained the more traditional measurements. Among these measures was the ounce, which was 1/16 pound.\nUntil the early 1900s, the United States did little to set a standard for measures. Different regions developed different standards, which hindered trade between the states. In 1905, the National Bureau of Standards called for a meeting to discuss the differences. In..

What is the temperature of Jupiter's great red spot?

Discovered in the 17th century, the Great Red Spot is a massive, persistent hurricane in Jupiter's atmosphere. The storm is large enough to accommodate over two Earth-sized objects within it and takes six Earth days to complete a rotation. The storm rotates counter-clockwise, but the small temperature difference between the body of the storm and the core creates a slight clockwise motion in the middle of the storm. The temperature variation also affects weather and wind speed in other regions of Jupiter.
