Why is the study of genetics important?

Around nine in 10 diseases arise because of genetic susceptibility. With the study of genetics, it is possible to predict some of them and reduce the risks. Although scientists do not have a full understanding of all genetic determinants of disease, research helps them reveal more information, which in turn gives them a chance to allocate more effective medications and treatments.In terms of family health, studying genetics allows people to prepare for inheritable disease. For example, both sickle cell anemia and cystic fibrosis have strong genetic components. Additionally, certain people are ..

What is the texture of pumice rock?

Igneous rocks comprise one of the three prominent types of rock formations. They are formed when hot molten material called magma, rises from the semi-fluid mantle or lower crust. The magma eventually cools down and either solidify on Earth's surface or within the crust.Igneous rocks are broadly categorized into two types: volcanic and plutonic. Volcanic rocks form on the surface from magma that underwent rapid cooling. Crystallization does not occur in volcanic rocks, which are typically fine-grained. The presence of flow banding and vesicles, or air sacs, is also evident on the surface ..

What is a biological disaster?

Epidemic-level biological disasters affect large numbers of people within a given community or area, whereas pandemic-level biological disasters effect a much larger region, sometimes spanning entire continents or the globe. Cholera is an epidemic-level biological disaster, while swine flu is a pandemic. Other epidemic examples include Ebola, dengue fever, malaria and the measles.\nThe United States Center for Disease Control (CDC) categorizes biological hazards that could potentially cause a biological disaster into four levels. These are classified as biosafety levels 1-4 or BSL 1-4. BSL 1 c..

What is the Blue lobelia?

Great blue lobelia grows in soil with adequate moisture and tolerates "wet feet." It needs lots of organic matter and grows to between 2 and 3 feet high with a spread of between 1 and 1 1/2 feet. It thrives in full sun to part shade and needs little care. Flowers arrive from July until September. Lobelia is a perennial and easily self-seeds.

What is the molecular geometry of NO3?

Nitrate contains one central nitrogen atom surrounded by three identically bonded oxygen atoms.\nVSEPR theory is a model used in chemistry to determine the geometry of individual molecules. When applying VESPR theory, the AXE method of electron counting is often used. The A represents the central atom, the X represents the number of atoms bonded to A and E represents the number of lone electron pairs surrounding the central atom. The sum of X and E is the steric number. The central nitrogen atom in nitrate has three X ligands due to the three bonded oxygen atoms. Because nitrogen has no lone e..

What is the function of the heartstrings?

The heartstrings, also called the chordae tendinese, are tendons. These tendons have a string-like appearance, which explains their alternative name of heartstrings.The right AV valve is the tricuspid by another name. The tricuspid is a valve that separates the right ventricle and the right atrium, and it allows deoxygenated blood to flow from the right atrium to the right ventricle.

What are heavenly bodies in astronomy?

The term astronomical object is also used to define naturally occurring physical entities that are observable in the universe. These objects are typically single cohesive structures such as asteroids, moons, planets and stars. Astronomical, heavenly or celestial bodies differ from astronomical objects. Astronomical objects are associated with a position in space, but these objects may not be a single cohesive structure, such as a star. They are often a grouping of many objects, such as a star cluster, nebula or galaxy. A comet can be defined as both an object and a body. It can be described as..

What are three minerals that glow under ultraviolet light?

Only around 15 percent of all minerals have the ability to fluoresce in ultraviolet light. In order for a mineral to fluoresce, it must contain an "activator" impurity such as a metal cation or a rare earth element.\nFluorite was the first observed fluorescent mineral and it glows blue. Calcite has been observed to glow many different colors including red, blue, white, pink, green and orange. Scapolite has been observed to have a yellow glow under ultraviolet light.

How does continental drift happen?

Wegener believed that all of the landmasses were originally joined together in a single landmass known as Pangaea. Pangaea is thought to have existed 240 million years ago; however, this large landmass or continent started breaking up, approximately 200 million years ago, into the continents that are known today.Underwater exploration by scientists has determined that continental drift is indeed an accurate theory. The seafloor is spreading at various places, and the new crust that forms pushes the two nearby plates further apart from one another. This is caused by the molten rock from within ..

What is creatine phosphate?

These are non-essential amino acids and the body's own supply travels through the blood stream to the cells where creatine is synthesized. Arginine and glycine form guanidinoacetate in the kidneys, whereas creatine phosphate synthesis is completed in the liver by the addition of S-adenosylmethionine. The University of Delaware states that the creatine phosphate helps the muscles and neuron cells replenish their fuel reserves.
