Acacia Tortilis
''Vachellia tortilis'', widely known as ''Acacia tortilis'' but now attributed to the genus ''Vachellia'' of the Mimosa Family ( Mimosaceae), is the umbrella thorn acacia, also known as umbrella thorn and Israeli babool, a medium to large canopied tree native to most of Africa, primarily to the savanna and Sahel of Africa (especially the Somali peninsula and Sudan), but also occurring in the Middle East. Distribution and growing conditions ''Vachellia tortilis'' is widespread in Africa, being found in countries like Tunisia, Morocco, Uganda, Angola, Zimbabwe, Djibouti, and Botswana. It tends to grow in areas where temperatures vary from and rainfall is anywhere from about per year. Characteristics In extremely arid conditions, it may occur as a small, wiry bush. In more favorable conditions, it grows up to in height. The tree carries leaves that grow to approx. in length with between 4 and 10 pair of pinnae each with up to 15 pairs of leaflets.

Serengeti National Park
The Serengeti National Park is a large national park in northern Tanzania that stretches over . It is located in eastern Mara Region and northeastern Simiyu Region and contains over of virgin savanna. The park was established in 1940. The Serengeti is well known for the largest annual animal migration in the world of over 1.5 million blue wildebeest and 250,000 zebra along with smaller herds of Thomson's gazelle and Common eland, eland. The national park is also home to the largest lion population in Africa. It is under threat from deforestation, population growth, poaching, and Ranch, ranching. Etymology The name "Serengeti" is often attributed to a Maasai language, Maasai word ''siringet'', meaning "the place where the land runs on forever" or "endless plains". However, this word does not appear in dictionaries of the language. History In 1930, an area of was designated as a game reserve in southern and eastern Serengeti.

Botswana
Botswana, officially the Republic of Botswana, is a landlocked country in Southern Africa. Botswana is topographically flat, with approximately 70 percent of its territory part of the Kalahari Desert. It is bordered by South Africa to the south and southeast, Namibia to the west and north, Zambia to the north, and Zimbabwe to the northeast. With a population of slightly over 2.4 million people and a comparable land area to France, Botswana is one of the List of countries and dependencies by population density, most sparsely populated countries in the world. It is essentially the nation-state of the Tswana people, who constitute nearly 80 percent of the population. The Tswana ethnic group are descended mainly from Bantu peoples, Bantu-speaking peoples who Bantu expansion, migrated into southern Africa, including modern Botswana, in several waves before AD 600. In 1885, the British Empire, British colonised the area and declared a protectorate named Bechuanaland. As part of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gum Arabic
Gum arabic (gum acacia, gum sudani, Senegal gum and by other names) () is a tree gum exuded by two species of '' Acacia sensu lato:'' '' Senegalia senegal,'' and '' Vachellia seyal.'' However, the term "gum arabic" does not indicate a particular botanical source. The gum is harvested commercially from wild trees, mostly in Sudan (about 70% of the global supply) and throughout the Sahel, from Senegal to Somalia. The name "gum Arabic" (''al-samgh al-'arabi'') was used in the Middle East at least as early as the 9th century. Gum arabic first found its way to Europe via Arabic ports and retained its name of origin. Gum arabic is a complex mixture of glycoproteins and polysaccharides, predominantly polymers of arabinose and galactose. It is soluble in water, edible, and used primarily in the food industry and soft drink industry as a stabilizer, with E number E414 (I414 in the US). Gum arabic is a key ingredient in traditional lithography and is used in printing, paints, glue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tannin
Tannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and Precipitation (chemistry), precipitate proteins and various other organic compounds including amino acids and alkaloids. The term ''tannin'' is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as carboxyls) to form strong complexes with various macromolecules. The term ''tannin'' (from scientific French ''tannin'', from French ''tan'' "crushed oak bark", ''tanner'' "to tan", cognate with English language, English ''tanning'', Medieval Latin ''tannare'', from Proto-Celtic ''*tannos'' "oak") refers to the abundance of these compounds in oak Bark (botany), bark, which was used in Tanning (leather), tanning animal Hide (skin), hides into leather. The tannin compounds are widely distributed in many species of plants, where they play a role in protection from predation (acting as pesticides) and might help in regulating plant ...

Fodder
Fodder (), also called provender (), is any agriculture, agricultural foodstuff used specifically to feed domesticated livestock, such as cattle, domestic rabbit, rabbits, sheep, horses, chickens and pigs. "Fodder" refers particularly to food given to the animals (including plants cut and carried to them), rather than that which they forage for themselves (called forage). Fodder includes hay, straw, silage, compressed and Compound feed, pelleted feeds, oils and mixed rations, and sprouting, sprouted grains and legumes (such as bean sprouts, fresh malt, or brewing#Brewer's spent grain, spent malt). Most animal feed is from plants, but some manufacturers add ingredients to processed feeds that are of animal origin. The worldwide animal feed trade produced 1.245 billion tons of compound feed in 2022 according to an estimate by the International Feed Industry Federation, with an annual growth rate of about 2%. The use of agricultural land to grow feed rather than human food can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ark Of The Covenant
The Ark of the Covenant, also known as the Ark of the Testimony or the Ark of God, was a religious storage chest and relic held to be the most sacred object by the Israelites. Religious tradition describes it as a wooden storage chest decorated in solid gold accompanied by an ornamental lid known as the mercy seat, Seat of Mercy. According to the Book of Exodus and Books of Kings, First Book of Kings in the Hebrew Bible and the Old Testament, the Ark contained the Tablets of Stone, Tablets of the Law, by which Yahweh, God delivered the Ten Commandments to Moses at Mount Sinai (Bible), Mount Sinai. According to the Book of Exodus, the Book of Numbers, and the Epistle to the Hebrews in the New Testament, it also contained Aaron's rod and a pot of manna. The biblical account relates that approximately one year after the Israelites' The Exodus, exodus from Egypt, the Ark was created according to the pattern that God gave to Moses when the Israelites were encamped at the foot of Mou ...

Tabernacle
According to the Hebrew Bible, the tabernacle (), also known as the Tent of the Congregation (, also Tent of Meeting), was the portable earthly dwelling of God used by the Israelites from the Exodus until the conquest of Canaan. Moses was instructed at biblical Mount Sinai, Mount Sinai to construct and transport the tabernacle with the Israelites on their journey through the wilderness and their subsequent conquest of the Promised Land. After 440 years, Solomon's Temple in Jerusalem superseded it as the dwelling-place of God. The main source describing the tabernacle is the biblical Book of Exodus, specifically Exodus 25–31 and 35–40. Those passages describe an inner sanctuary, the Holy of Holies, created by the veil suspended by four pillars. This sanctuary contained the Ark of the Covenant, with its cherubim-covered mercy seat. An outer sanctuary (the "Holy Place") contained a gold lamp-stand or candlestick. On the north side stood a table, on which lay the showbread. On th ...

Israelites
Israelites were a Hebrew language, Hebrew-speaking ethnoreligious group, consisting of tribes that lived in Canaan during the Iron Age. Modern scholarship describes the Israelites as emerging from indigenous Canaanites, Canaanite populations and other peoples.Mark Smith in "The Early History of God: Yahweh and Other Deities of Ancient Israel" states "Despite the long regnant model that the Canaanites and Israelites were people of fundamentally different culture, archaeological data now casts doubt on this view. The material culture of the region exhibits numerous common points between Israelites and Canaanites in the Iron I period (c. 1200–1000 BCE). The record would suggest that the Israelite culture largely overlapped with and derived from Canaanite culture ... In short, Israelite culture was largely Canaanite in nature. Given the information available, one cannot maintain a radical cultural separation between Canaanites and Israelites for the Iron I period." (pp. ...

Frost Resistance
Frost resistance is the ability of plants to survive cold temperatures. Generally, land plants of the northern hemisphere have higher frost resistance than those of the southern hemisphere. An example of a frost resistant plant is ''Drimys winteri'' which is more frost-tolerant than naturally occurring conifers and vessel-bearing angiosperms such as the ''Nothofagus'' that can be found in its range in southern South America. The physiological process of cold acclimatization is induced in fall and early winter by low above- zero temperatures (cold) and includes complex reprogramming of the cellular environment to induce enhanced frost tolerance.Temperate climate fruit trees reach their highest resistance in the middle of winter. Since freezing belongs to dehydration stresses, cold acclimation process is associated with an enhanced accumulation of osmolytes (sugars, proline, polyamines, and hydrophilic proteins). The loss of frost resistance occurs after warming. Rapid temperature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
