A xerocole (from Greek xēros / ˈ z ɪ r oʊ s / 'dry' and Latin col(ere) 'to inhabit'), [2] [3] [4] is a general term referring to any animal that is adapted to live in a desert. The main challenges xerocoles must overcome are lack of water and excessive heat. To conserve water they avoid evaporation and concentrate excretions (i.e. urine and ...
The study of Epigenetics explains how certain mutations (e.g., histone modification and DNA methylation) affect how genes are expressed without altering the genetic code, suggesting learning from the environment can change gene expression, and thus neural pathways, to modify the animals behaviour within its lifetime.

A single-displacement reaction, also known as single replacement reaction or exchange reaction, is an archaic concept in chemistry. It describes the stoichiometry of some chemical reactions in which one element or ligand is replaced by an atom or group. [1] [2] [3] It can be represented generically as:
The Asiatic cheetah occurred in the desert west of Basrah until 1926. The last known cheetah in the country was killed by a car. [24] The last known Asiatic lion was killed on the lower Tigris in 1918. [1] The last Arabian oryx was shot in 1914. Syrian elephants roamed Mesopotamia until around 700 BC.
The Gobi Desert is the fastest expanding desert on Earth, as it transforms over 3,600 square kilometres (1,400 square miles) of grassland into wasteland annually. [58] Although the Gobi Desert itself is still a distance away from Beijing , reports from field studies state there are large sand dunes forming only 70 km (43.5 mi) outside the city.
The work consists of a long trench in the earth, 30 feet (9 m) wide, 50 feet (15 m) deep, and 1500 feet (457 m) long, created by the displacement of 244,000 tons of rock, mostly rhyolite and sandstone. Two trenches straddle either side of a natural canyon (into which the excavated material was dumped).
Leiurus quinquestriatus can be found in desert and scrubland habitats ranging from North Africa through to the Middle East. Its range covers a wide sweep of territory in the Sahara, Arabian Desert, Thar Desert, and Central Asia, from Algeria and Mali in the west through to Egypt, Ethiopia, Asia Minor and the Arabian Peninsula, eastwards to Kazakhstan and western India in the northeast and ...
