Snake Lord
Snakes are elongated limbless reptiles of the suborder Serpentes (). Cladistically squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales much like other members of the group. Many species of snakes have skulls with several more joints than their lizard ancestors and relatives, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most only have one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have independently evolved elongate bodies without limbs or with greatly reduced limbs at least twenty-five times via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is ...

After the classic came the post classic which was characterized by a decline in Maya civilization. During that time both Tikal and Calakmul were abandoned. Dos Pilas In 629 Ajaw Kʼinich Muwaan Jol II of Tikal made his son Bʼalaj Chan Kʼawiil ( in the Maya writing system) ruler of Dos Pilas, a newly founded vassal state of Tikal. B'alaj Chan K'awiil was a major protagonist in the bitter factional dispute between two lords carrying the same emblem glyph. The clash emerged from the obscurity of Tikal's 130-year Hiatus and coincided with the epic contest for political ascendency between Tikal and Calakmul. Bʼalaj Chan Kʼawiil's claim to the royal emblem of Mutal was evidently based on him being the son of K'inich Muwaan Jol, as s ...

Pharmacology
Pharmacology is the science of drugs and medications, including a substance's origin, composition, pharmacokinetics, pharmacodynamics, therapeutic use, and toxicology. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals. The field encompasses drug composition and properties, functions, sources, synthesis and drug design, molecular and cellular mechanisms, organ/systems mechanisms, signal transduction/cellular communication, molecular diagnostics, interactions, chemical biology, therapy, and medical applications and antipathogenic capabilities. The two main areas of pharmacology are pharmacodynamics and pharmacokinetics. Pharmacodynamics studies the effects of a drug on biological systems, and pharmacokinetics studies the effects of biological systems on a drug. In broad terms, pharmacod ...

Western Turkic Khaganate
The Western Turkic Khaganate () or Onoq Khaganate () was a Turkic khaganate in Eurasia, formed as a result of the wars in the beginning of the 7th century (593–603 CE) after the split of the First Turkic Khaganate (founded in the 6th century on the Mongolian Plateau by the Ashina clan), into a western and an eastern Khaganate. The whole confederation was called ''Onoq'', meaning "ten arrows". According to a Chinese source, the Western Turks were organized into ten divisions. The khaganate's capitals were Navekat (summer capital) and Suyab (principal capital), both situated in the Chui River valley of Kyrgyzstan, to the east of Bishkek.

Conquest Of The Western Turks
The conquest of the Western Turks, known as the Western Tujue in Chinese sources, was a military campaign in 655–657 led by the Tang dynasty generals Su Dingfang and Cheng Zhijie against the Western Turkic Khaganate ruled by Ashina Helu.
