Silky Swallow-wort is a common name of two plants in the genus "Asclepias":
Guitar chord
A guitar chord is made up of two or more notes, played on a guitar at one time. Chord voicings, that is the choice of individual notes in the chord, can be changed for many different purposes and playing styles.
The guitar is very capable and useful for playing chords; but it does have some differences with other instruments. Most guitars only have six strings. This means that for the very largest of chord-voicings it is often necessary to not use one or more tones from the chord. The layout of notes on the fretboard sometimes means that the notes in a chord are not played in tonal order, or make possible a chord that is composed of more than one note of the same pitch. Many chords can be played with the same notes in more than one place on the fretboard.
Guitars can vary both in the number of strings they have. They can also be tuned differently. Most guitars used in popular music have six-strings and are tuned : E-A-D-G-B-E. Usually the string with the highest pitch (the thinnest) is called the first string, and the string having the lowest pitch (the thickest) is called the sixth.
Asclepias tuberosa
Asclepias tuberosa (also known as the butterfly flower) is a species of milkweed plant. It belongs in the subfamily Asclepiadoideae. It is native to North America. It blooms from June to September. The flowers are orange, red-orange, or yellow. This species is found in prairies, meadows, and fields. It likes well-drained soil and sunny or partly shaded places. Butterfly Weed grows from 0.3 to 0.9 meters tall (1–3 feet).
It has many other names, including the butterfly weed, the Canada root, the chigger flower (or chiggerflower), the fluxroot, the Indian paintbrush, the Indian posy, the orange milkweed, the orange swallow-wort, the Pleurisy Root, the silky swallow-wort, the tuber root, the yellow milkweed, the white-root, and the windroot.
Butterfly Weed has many common names. Here is a list of them:

Indian Paintbrush
Indian Paintbrush is a common name for different plants:
Intel Core i7
Intel Core i7 is a name that the company Intel uses for the computer processors it makes for high-end desktop and laptop computers and tablets. Intel uses this name for the fastest processors that they think will be used to build the most powerful consumer devices. The 'Core' part of the name, which refers to the processor's core, has been used by Intel since 2006, but the first Core i7 processor was released 3 years later in 2009.
There are different types of Core i7 processor. The name does not name a type. Instead, it is the name for all of the fast processors that Intel thinks should be sold to consumers. Intel uses two other "Core i-" names for its processors for consumers: "Core i5" and "Core i3." The "Core i5" processors are mostly as fast as i7 processors, but lack the Hyper Threading technology which allows each core to be used twice simultaneously giving the impression of doubling the cores.
Intel uses a different name, Xeon, for processors that Intel makes for "server" computers for businesses (and some rare laptops). Some of the "Core i7" processors are almost the same as some of the "Xeon" processors, but each of the Xeon processors is a little bit different than the "Core i7" processor, because a "server" computer is not the same as a consumer computer. Intel also makes other "Xeon" processors that are not the same as any "Core i7" processor. Unlike the Core i7, Xeon processors support ECC (error corrected) memory, and multiple CPUs on the same motherboard.
Asclepias verticillata
Asclepias verticillata (Whorled Milkweed or Horsetail Milkweed) is a particular kind of milkweed used as a medicinal plant. It is native to North America. It blooms in the summer. The flowers are white or pale green. It is found in fields, open woodlands, and prairies. Whorled Milkweed likes dry soil and sunny or partly shaded places. It grows from 0.3 to 0.9 meters tall (1–3 feet).
Sacred dance
Sacred dance is a kind of dance that all movements that are religious in nature. An example of a sacred dance is the dance done by a whirling dervish.
Population genetics
Population genetics is the branch of genetics which studies the genetic composition of populations. It brings together genetics, evolution, natural selection, breeding, statistics and mathematics. Mathematical and computer models are produced, and field research is done to test the models.
Starting, perhaps, with G. Udny Yule's paper in 1902, population theorists tackled key issues in genetics and evolution. G.H. Hardy and Wilhelm Weinberg showed that if a population had random mating, no selection, migration or mutation, then the proportion of alleles would remain the same generation after generation. This was the Hardy–Weinberg law, the first great result of this new field of research.
Population genetics made great progress from 1918 to 1937. During this period, Ronald Fisher, J.B.S. Haldane and Sewall Wright worked on the connection between evolution and genetics, using new mathematical techniques, such as statistical probability. E.B. Ford and Theodosius Dobzhansky did field research on the genetics of natural populations of lepidoptera and "Drosophila", respectively. Broadly speaking, this work proved that the newly rediscovered Mendelian genetics could be reconciled with Darwinian evolution. This laid the groundwork for the modern evolutionary synthesis, which took place in the following years, from about 1937 to 1953.
In the second half of the 20th century, population geneticists tackled a range of complex evolutionary problems, such as the evolution of sex, sexual selection, kin selection (altruism), mimicry and molecular evolution. The key figures included John Maynard Smith, Motoo Kimura and William Hamilton. Techniques developed for population genetics help to decide what contribution heredity and environment make in developmental biology.
Calotropis gigantea
Crown flower ("Calotropis gigantea") is a species of plant. It is also known as Giant Milkweed. It belongs in the subfamily Asclepiadodeae. It is native to southeast Asia. It has been naturalized in Hawai'i.
Calotropis procera
Apple of Sodom ("Calotropis procera") is a species of plant. It is also known as Roostertree. It belongs in the subfamily Asclepiadoideae.
It is native to North Africa, Central Africa, Western Asia, South Asia, and Indochina. It has been naturalized in Puerto Rico, the United States Virgin Islands, Hawai'i, and southern California.
Cynanchum laeve
Sand Vine ("Cynanchum laeve") is a species of plant. It is also known as Honeyvine, Honeyvine Milkweed, Bluevine Milkweed, Climbing Milkweed, and Smooth Swallow-wort. It belongs in the subfamily Asclepiadoideae. It is native to North America. It blooms from June to August. This species is found in a variety of habitats such as edges of woodlands, near stream edges, gardens, and fields. This vine can grow to be 6 or more feet long.
Hardy–Weinberg law
The Hardy–Weinberg law was developed independently by an English mathematician, G.H. Hardy, and a German doctor, Wilhelm Weinberg. This concept is also known as the "Hardy–Weinberg equilibrium", "Hardy–Weinberg theorem" or "Hardy–Weinberg principle". Sometimes Weinberg's name is placed first.
The law is a foundation of population genetics, and it is still taught to students today. It states that the proportions of alleles of all genes in any population will remain the same unless perturbed (disturbed). That applies to all loci on all chromosomes in the population. Possible perturbations are:
