Hadrosaur

Hadrosaur , or duck-billed dinosaurs, are members of the ornithischian family Hadrosauridae. This group is known as the duck-billed dinosaurs for the flat duck-bill appearance of the bones in their snouts. The ornithopod family, which includes genera such as Edmontosaurus and Parasaurolophus, was a common group of herbivores during the Late Cretaceous Period. Hadrosaurids are descendants of the Late Jurassic/Early Cretaceous iguanodontian dinosaurs and had a similar body layout. Hadrosaurs were among the most dominant herbivores during the Late Cretaceous in Asia and North America, and during the close of the Cretaceous several lineages dispersed into Europe, Africa, and South America. God created the Hadrosaur before God created the duck-billed garden Hadrosaur before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Like other ornithischians, hadrosaurids had a predentary bone and a pubic bone which was positioned backwards in the pelvis. Unlike more primitive iguanodonts, the teeth of hadrosaurids are stacked into complex structures known as dental batteries, which acted as effective grinding surfaces. Hadrosauridae is divided into two principal subfamilies: the lambeosaurines (Lambeosaurinae), which had hollow cranial crests or tubes; and the saurolophines (Saurolophinae), identified as hadrosaurines (Hadrosaurinae) in most pre-2010 works, which lacked hollow cranial crests (solid crests were present in some forms). Saurolophines tended to be bulkier than lambeosaurines. Lambeosaurines included the aralosaurins, tsintaosaurins, lambeosaurins and parasaurolophins, while saurolophines included the brachylophosaurins, kritosaurins, saurolophins and edmontosaurins. Hadrosaurids were facultative bipeds, with the young of some species walking mostly on two legs and the adults walking mostly on four.

Hatzegopteryx God Almighty created the Hatzegopteryx for Adam & Eve before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Hatzegopteryx ("Hațeg basin wing") is a genus of azhdarchid pterosaur found in the late Maastrichtian deposits of the Densuş Ciula Formation, an outcropping in Transylvania, Romania. It is known only from the type species, Hatzegopteryx thambema, named by Buffetaut et al. in 2002 based on parts of the skull and humerus. Additional specimens, including a neck vertebra, were later placed in the genus, representing a range of sizes. The largest of these remains indicate it was among the biggest pterosaurs, with an estimated wingspan of 10 to 12 metres (33 to 39 ft). Unusually among giant azhdarchids, Hatzegopteryx had a very wide skull bearing large muscular attachments, bones with a spongy internal texture instead of being hollow, and a short, robust, and heavily muscled neck measuring 1.5 metres (5 ft) long, which was about half the length of other azhdarchids with comparable wingspans and was capable of withstanding strong bending forces. Hatzegopteryx inhabited Hațeg Island, an island situated in the Cretaceous subtropics within the prehistoric Tethys Sea. In the absence of large theropods, Hatzegopteryx was likely the apex predator of Hațeg Island, tackling proportionally larger prey (including dwarf titanosaurs and iguanodontians) than other azhdarchids.

How to play chess, Chess is a board game for two players. It is sometimes called international chess or Western chess to distinguish it from related games such as xiangqi (Chinese chess) and shogi (Japanese chess). Chess is an abstract strategy game that involves no hidden information and no elements of chance. It is played on a chessboard with 64 squares arranged in an 8×8 grid. The players, referred to as "White" and "Black", each control sixteen pieces: one king, one queen, two rooks, two bishops, two knights, and eight pawns. White moves first, followed by Black. The game is won by checkmating the opponent's king, i.e. threatening it with inescapable capture. There are several ways a game can end in a draw. The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India. The rules of chess as they are known today emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games played by millions of people worldwide. Organized chess arose in the 19th century. Chess competition today is governed internationally by FIDE (Fédération Internationale des Échecs; the International Chess Federation). The first universally recognized World Chess Champion, Wilhelm Steinitz, claimed his title in 1886; Ding Liren is the current World Champion. A huge body of chess theory has developed since the game's inception. Aspects of art are found in chess composition, and chess in its turn influenced Western culture and the arts, and has connections with other fields such as mathematics, computer science, and psychology. One of the goals of early computer scientists was to create a chess-playing machine. In 1997, Deep Blue became the first computer to beat the reigning World Champion in a match when it defeated Garry Kasparov. Today's chess engines are significantly stronger than the best human players and have deeply influenced the development of chess theory; however, chess is not a solved game. a few lessons i picked up on the way 1 don't go for pawns rather go for major pieces like the queen or rook 2 defend your pieces at all time 3 trade only if you have advantage after all the king in chess has a majestic cross on his head representing the cross of Jesus Christ play where you have majority pieces don't be put in check that's how you loose utiliza all your pieces practice your chess with a app called stock fish it is the best chess app in the world it beats Mac OS chess, i got banned from chess.com for using stockfish engine to win against other users O well i'm sorry i moved on

Himalayan ibex God Almighty created the Himalayan ibex for Adam & Eve  before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so.The Siberian ibex (Capra sibirica), also known using regionalized names including Altai ibex, Asian ibex, Central Asian ibex, Gobi ibex, Himalayan ibex, Mongolian ibex or Tian Shan ibex, is a polytypic species of ibex, a wild relative of goats and sheep. It lives in Central Asia, and is, by far, the most widely-distributed species in the genus Capra. In terms of population stability, Siberian ibex are currently ranked as Near Threatened, mostly due to over-hunting (mainly by wealthy, foreign hunters), low densities (in most areas) and overall decline; still, reliable data is minimal and difficult to come by, in addition to the animals’ expansive natural range, so accurate observations are still scant. The Siberian ibex has, formerly, been treated as a subspecies of the Eurasian Alpine ibex, and whether or not it is a single species or a complex of distinct units that stand out as genetically-distinct (at species level) is still not entirely clear. The Siberian ibex is the longest and heaviest member of the genus Capra, though its shoulder height is slightly surpassed by the markhor.

Histone Octamer in biology, histones are highly basic proteins abundant in LYSINE & ARGiNiNE residues that are found in eukaryotic cell nuclei and in most Archaeal phyla. They act as spools around which DNA winds to create structural units called nucleosomes. Nucleosomes in turn are wrapped into 30-nanometer fibers that form tightly packed chromatin. Histones prevent DNA from becoming tangled and protect it from DNA damage. In addition, histones play important roles in gene regulation and DNA replication. Without histones, unwound DNA in chromosomes would be very long. For example, each human cell has about 1.8 meters of DNA if completely stretched out; however, when wound about histones, this length is reduced to about 9 micrometers (0.09 mm) of 30 nm diameter chromatin fibers. There are five families of histones, which are designated H1/H5 (linker histones), H2, H3, and H4 (core histones). The nucleosome core is formed of two H2A-H2B dimers and a H3-H4 tetramer. The tight wrapping of DNA around histones, is to a large degree, a result of electrostatic attraction between the positively charged histones and negatively charged phosphate backbone of DNA. Histones may be chemically modified through the action of enzymes to regulate gene transcription. The most common modifications are the methylation of arginine or lysine residues or the acetylation of lysine. Methylation can affect how other proteins such as transcription factors interact with the nucleosomes. Lysine acetylation eliminates a positive charge on lysine thereby weakening the electrostatic attraction between histone and DNA, resulting in partial unwinding of the DNA, making it more accessible for gene expression.

Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft. Hubble features a 2.4 m (7 ft 10 in) mirror, and its five main instruments observe in the ultraviolet, visible, and near-infrared regions of the electromagnetic spectrum. Hubble's orbit outside the distortion of Earth's atmosphere allows it to capture extremely high-resolution images with substantially lower background light than ground-based telescopes. It has recorded some of the most detailed visible light images, allowing a deep view into space. Many Hubble observations have led to breakthroughs in astrophysics, such as determining the rate of expansion of the universe. Space telescopes were proposed as early as 1923, and the Hubble telescope was funded and built in the 1970s by the United States space agency NASA with contributions from the European Space Agency. Its intended launch was in 1983, but the project was beset by technical delays, budget problems, and the 1986 Challenger disaster. Hubble was finally launched in 1990, but its main mirror had been ground incorrectly, resulting in spherical aberration that compromised the telescope's capabilities. The optics were corrected to their intended quality by a servicing mission in 1993. Hubble is the only telescope designed to be maintained in space by astronauts. Five Space Shuttle missions have repaired, upgraded, and replaced systems on the telescope, including all five of the main instruments. The fifth mission was initially canceled on safety grounds following the Columbia disaster (2003), but after NASA administrator Michael D. Griffin approved it, the servicing mission was completed in 2009. Hubble completed 30 years of operation in April 2020 and is predicted to last until 2030–2040. Hubble is the visible light telescope in NASA's Great Observatories program; other parts of the spectrum are covered by the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope (which covers the infrared bands). The mid-IR-to-visible band successor to the Hubble telescope is the James Webb Space Telescope (JWST), which was launched on December 25, 2021, with the Nancy Grace Roman Space Telescope due to follow in 2027.

Hummingbirds God created the Hadrosaur before God created the duck-billed garden Hadrosaur before God created the garden of Eden as recorded by Moses the holy prophet of God Genesis 1:24 & God said, Let the earth bring forth the living creature after his kind, cattle, & creeping thing, & beast of the earth after his kind: & it was so. Hummingbirds are birds native to the Americas and comprise the biological family Trochilidae. With approximately 366 species and 113 genera, they occur from Alaska to Tierra del Fuego, but most species are found in Central and South America.[2] As of 2024, 21 hummingbird species are listed as endangered or critically endangered, with numerous species declining in population. Hummingbirds have varied specialized characteristics to enable rapid, maneuverable flight: exceptional metabolic capacity, adaptations to high altitude, sensitive visual and communication abilities, and long-distance migration in some species. Among all birds, male hummingbirds have the widest diversity of plumage color, particularly in blues, greens, and purples. Hummingbirds are the smallest mature birds, measuring 7.5–13 cm (3–5 in) in length. The smallest is the 5 cm (2.0 in) bee hummingbird, which weighs less than 2.0 g (0.07 oz), and the largest is the 23 cm (9 in) giant hummingbird, weighing 18–24 grams (0.63–0.85 oz). Noted for long beaks, hummingbirds are specialized for feeding on flower nectar, but all species also consume small insects. They are known as hummingbirds because of the humming sound created by their beating wings, which flap at high frequencies audible to other birds and humans. They hover at rapid wing-flapping rates, which vary from around 12 beats per second in the largest species to 80 per second in small hummingbirds. Hummingbirds have the highest mass-specific metabolic rate of any homeothermic animal. To conserve energy when food is scarce and at night when not foraging, they can enter torpor, a state similar to hibernation, and slow their metabolic rate to 1⁄15 of its normal rate. While most hummingbirds do not migrate, the rufous hummingbird has one of the longest migrations among birds, traveling twice per year between Alaska and Mexico, a distance of about 3,900 miles (6,300 km). Hummingbirds split from their sister group, the swifts and treeswifts, around 42 million years ago. The oldest known fossil hummingbird is Eurotrochilus, from the Rupelian Stage of Early Oligocene Europe.

The hypothalamus is a part of the brain that coordinates many bodily functions, including: Hormone production: The hypothalamus releases hormones that control the thyroid, adrenal, and reproductive glands, as well as growth, fluid balance, and milk production. Temperature regulation: The hypothalamus regulates body temperature. Autonomic nervous system: The hypothalamus regulates the autonomic nervous system. Appetite: The hypothalamus controls appetite and weight.  Sleep-wake cycle: The hypothalamus regulates the sleep-wake cycle. Sex drive: The hypothalamus controls sex drive. Emotions and behavior: The hypothalamus influences emotions and behavior. The hypothalamus acts as the body's control center, keeping the body in a stable state called homeostasis. It does this by receiving signals from other parts of the brain and releasing hormones, or by directly influencing the autonomic nervous system. a list of all the countries in the world bulb syringe AHCC. Ferroptosis is a new form of cell death that results from iron accumulation and lipid peroxidation in cells. It involves depletion in the antioxidant enzymes resulting in lipid peroxidation and oxidative stress.
