Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves. Cells have many parts, each with a different function. Som…
Turtles are in the class Reptilia, which includes snakes, crocodiles, and lizards. Marine turtles belong to the order Testudines, the first specimens date back 220 million years. Marine turtles are thought to have come from land turtles and freshwater turtles that lived about 230 million years ago in the Cretaceous period. The earliest sea turtle ancestor found so far is Desmatochelys padil…
Information about cattle instincts and associated behavior is a valuable tool that helps producers understand why cattle behave or respond as they do. Although cattle have been domesticated for a very long time, they are dictated by the herding instinct, especially if they perceive a dangerous situation. Cattle depend heavily upon sight, and they have a nearly 360-degree panoramic view. This vi…
Napier grows in low to medium altitudes. Napier grows in an altitude of up to 2000 m above sea level. However, altitudes of 2000m and above cause slow regeneration of Napier. Napier performs best if rainfall is above 950mm per year. Napier performs well in annual temperatures ranging between 18.3 °C to 26.6°C . In highland areas where morning frost occurs it should be noted that Napier grass …

Composition of processed vanilla beans is fairly variable and complex due to a number of variables such as species, growth conditions, soil composition, fruit maturity and mainly, the type of processing. All these variables define the relative content of the chemical constituents in the processed beans, which makes it difficult to define their typical composition. Ranadive (1994) reported a com…
Feral camels live in three main types of non-territorial groups: year-round groups of bulls (males), summer groups of cows (females) and calves, and winter breeding groups that include a mature bull and several cows with calves. Old bulls tend to be solitary (DEH 2004). Herds average 11 individuals but larger herds of up to several hundred animals may form in summer or during droughts when grou…

Today, eggs usually are picked up from the producer 3 or 4 times a week. Often, eggs arrive at the breaking plant on the same day they are laid. Eggs are gathered often on automatic belts and refrigerated on the farm. All eggs are washed at the breaking plant under closely controlled temperature conditions using approved detergent sanitizers. These changes have greatly enhanced the retention of…
For many years, this elementary treatise on advanced Euclidean geometry has been the standard textbook in this area of classical mathematics; no other book has covered the subject quite as well. It explores the geometry of the triangle and the circle, concentrating on extensions of Euclidean theory, and examining in detail many relatively recent theorems. Several hundred theorems and corollarie…
Translated into many languages, this book was in continuous use as the standard university-level text for a quarter century, until it was revised and enlarged by the author in 1952. The first part of the text stresses construction problems, proceeding to surveys of similitude and homothecy, properties of the triangle and the quadrilateral, and harmonic division. Subsequent chapters explore the…
