Listed below are some notable groups and populations from South Asia by human Y-chromosome DNA haplogroups based on various relevant studies.. The samples are taken from individuals identified with specific linguistic designations (IE=Indo-European, Dr=Dravidian, AA=Austro-Asiatic, ST=Sino-Tibetan) and individual linguistic groups, the third column (n) gives the sample size studied, and the ...
Y-DNA lineages E-V12 and E-V22 have been associated with a Levantine source (represented by modern Lebanese), while North African haplogroup E-M81 shows an average frequency of 1.53% in the current Sicilian and Southern Italian genetic pool, but the typical Maghrebin core haplotype 13-14-30-24-9-11-13 has been found in only two out of the five ...
The basic elements of the scientific method are illustrated by the following example (which occurred from 1944 to 1953) from the discovery of the structure of DNA (marked with and indented). In 1950, it was known that genetic inheritance had a mathematical description, starting with the studies of Gregor Mendel , and that DNA contained genetic ...
The use of schematic diagrams can replace long descriptions or complicated drawings as a tool for understanding both floral structure and evolution. Such diagrams may show important features of flowers, including the relative positions of the various organs, including the presence of fusion and symmetry, as well as structural details.

An infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. [1] An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection.
Human migration is the movement of people from one place to another, [1] with intentions of settling, permanently or temporarily, at a new location (geographic region). The movement often occurs over long distances and from one country to another (external migration), but internal migration (within a single country) is the dominant form of human migration globally.
When this occurs, the microtubules disintegrate, destroying the structure of the cell's cytoskeleton which collapses the neuron's transport system. [77] A number of studies connect the misfolded amyloid beta and tau proteins associated with the pathology of Alzheimer's disease, as bringing about oxidative stress that leads to neuroinflammation ...
