What is a good source to find flower names?

The Better Homes and Gardens website, BHG.com, is an excellent source for names, pictures and growing information on an assortment of garden flowers. The information is searchable by plant type, growth characteristics and special features of the plant.\nFor information on wildflowers, it is best to identify a particular region of interest due to the vast number plant species. For example, GoBotany offers a simple key for identifying wildflowers specific to New England. IllinoisWildflower.info has information on flowers native to Illinois and the Midwest, organized by habitat type and growth ch..

How can the sun be described?

Based on its spectral classification, the sun is a G-type main-sequence or GV2 star and accounts for approximately 99.86 percent of the mass present in Earth's solar system. The sun's core, which represents about 30 percent of its radius, comprises about 94 percent of its entire mass. The temperature at the center of the core is 27 million degrees Fahrenheit. By the time the heat carried by convection from the sun's core travels the distance to its surface, the temperature will have been reduced to 9,900 degrees F.The sun produces its heat energy through a thermonuclear fusion p..

How does detergent break surface tension?

The hydrogen and oxygen molecules in water form hydrogen bonds, which form a type of skin on the surface of the water. This skin is strong enough to support the weight of very light objects. That is why ants seem to walk on the surface of a body of water and why a needle carefully placed on top of the water will float.\n\nAccording to the Nuffield Foundation, detergent molecules have a polar head on one edge that attracts water and a polar head on the other edge that repels water. These opposing heads interfere with the hydrogen bonds in the water molecules and weaken the strength of the skin ..

How big is 6 mm?

Several types of ammunition are described as 6 millimeter calibers. A caliber measures the internal diameter of a firearm barrel and the diameter of the bullet that travels down said barrel. Although the various ammunition are described as being 6 millimeters, the diameter of the bullets of these rounds are generally 6.17 millimeters and above.

What are the prime movers of the ankle plantar flexion?

The gastrocnemius and soleus together are called the triceps surae. Together, they form a complex of three muscles, because the gastrocnemius has two heads that attach from the knee to the foot through the Achilles tendon. The soleus attaches to the two lower leg bones, the tibia and fibula. The soleus and gastrocnemius fold around each other, forming a bulge with a cleft at the calf when the muscles are well-developed.\nMany muscles assist with plantar flexion of the ankle, a movement akin to pointing the toes. The synergist muscles assist the flexion. Antagonist muscles lengthen as the prime..

Why are metals malleable and ductile?

The sliding of atoms when force is applied is the reason that metals can change their shapes. Since all things are made of atoms, including metal, the atoms must be moved in order to change the shape of the metal. Whether a metal is malleable, ductile or both, most metals are able to be changed with the use of force because their atoms are movable. In most, if not all metals, it is easier for the atoms to move when they are heated which is the reason that most metals are melted down or heated up before they are moved into a different shape.\n\nMost metals are both malleable and ductile, but ma..

What factors affect metabolism?

According to WebMD, the older people get, the slower the metabolism becomes. This is why people gain weight as they age. Extra body fat that is gained further decreases metabolism. By burning extra calories of food before they are stored as fat as well as burning the existing extra fat, metabolism can be increased. To achieve weight loss and boost metabolism, more calories need to be burned than consumed. Exercising speeds up the metabolism, and for hours after, calories can still be burned. Eventually, muscle is formed and in turn promotes a boost in metabolism.\nWebMD reports that eating a h..

What was Erwin Chargaff's discovery?

Although Watson and Crick cited Chargiff for their Nobel Prize-winning discovery, Chargaff would never be rewarded for his efforts. Later in his life he became openly critical of scientists, who worked in the field of molecular biology, stating that they were involved in "the practice of biochemistry without a licence." He died on June 20, 2002, at the age of 96.

What is the largest canyon in the world?

The Grand Canyon is contained within a 1,904-square-mile park divided into a North Rim and a South Rim section. Visitors looking down from the rim of the canyon can see several buttes, spires and mesas. These formations are actually mountains that are over 2,000 feet tall.\nThough the Grand Canyon is very deep, the Cotahusi Canyon in Peru is the deepest in the world, boasting a depth of over 2 miles.

What causes gravity?

In the late 1600s, Sir Isaac Newton shared his theory of universal gravitation with the public. This theory defines the gravitational force between two objects as the product of the masses of the objects multiplied by the gravitational constant and divided by the square of the distance between the objects. Unless one of the bodies is massive, the force of gravity is relatively small.\nIn the early 20th century, Einstein turned his attention toward gravitation. He saw gravity as a curve in the time-space continuum, not as a force. However, neither Newton nor Einstein provided a complete underst..
