Parthenogenesis
Parthenogenesis (; from the Greek grc, παρθένος, translit=parthénos, lit=virgin, label=none + grc, γένεσις, translit=génesis, lit=creation, label=none) is a natural form of asexual reproduction in which growth and development of embryos occur in a gamete (egg or sperm) without combining with another gamete (e.g., egg and sperm fusing). In animals, parthenogenesis means development of an embryo from an unfertilized Gametophyte, egg cell. In plants, parthenogenesis is a component process of apomixis. In algae, parthenogenesis can mean the development of an embryo from either an individual sperm or an individual egg. Parthenogenesis occurs naturally in some plants, algae, invertebrate animal species (including nematodes, some tardigrades, water fleas, some scorpions, aphids, some mites, some bees, some Phasmatodea and parasitic wasps) and a few vertebrates (such as some fish, amphibians, reptiles and birds). This type of reproduction has been induced artificially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whiptail Lizard
Teiidae is a family of autarchoglossan lizards native to the Americas. Members of this family are generally known as whiptails or racerunners; however, tegus also belong to this family. Teiidae is sister to the Gymnopthalmidae, and both families comprise the Teiioidea. The Teiidae includes several parthenogenic species – a mode of clonal reproduction. Presently, the Teiidae consists of approximately 150 species in eighteen genera. Morphology and behavior Teiids can be distinguished from other lizards by the following characteristics: they have large rectangular scales that form distinct transverse rows ventrally and generally small granular scales dorsally, they have head scales that are separate from the skull bones, and the teiid teeth are solid at the base and "glued" to the jaw bones. Additionally, all teiids have a forked, snake-like tongue. They all possess well-developed limbs. Teiids are all terrestrial (few are semi-aquatic) and diurnal, and are primarily carnivor ...

Electric Ant
The little fire ant (''Wasmannia auropunctata''), also known as the electric ant, is a small (approx long), light to golden brown (ginger) social ant native to Central and South America, now spread to parts of Africa (including Gabon and Cameroon), Taiwan, North America, Puerto Rico, Israel, Cuba, and six Pacific Island groups (including the Galápagos Islands, Hawaii, New Caledonia and the Solomon Islands) plus north-eastern Australia ( Cairns).Electric ant (''Wasmannia auropunctata'') webpage Accessed 7 March 2009 It is a very harmful invasive species. The name, electric ant (or little fire ant), derives from the ant's painful sting relative to its size. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beltsville Small White
The Beltsville Small White is a breed of domestic turkey. The bird was named after its physical characteristics—a relatively small size and entirely white plumage—as well as its place of origin: the United States Department of Agriculture's Beltsville Agricultural Research Center in Maryland. Description Small Whites have entirely white plumage, with a red to bluish-white head, black beard, horn colored beak, and dark brown eyes. Their shanks and toes typically pinkish white. At market, Beltsville Small White toms will weigh around 17 pounds, while a mature hen will weigh 9-10 pounds. Their eggs are usually pale bluff with reddish-brown dots. History Development for the Small White began in the 1930s in response to market research that said consumers wanted a turkey of small to medium size with no dark pinfeathers and more white meat. In 1934, the Beltsville Research Center started a seven-year breeding and research program; led by Stanley J. Marsden and lasting until 19 ...

Teratoma
A teratoma is a tumor made up of several different types of tissue, such as hair, muscle, teeth, or bone. Teratomata typically form in the ovary, testicle, or coccyx. Symptoms Symptoms may be minimal if the tumor is small. A testicular teratoma may present as a painless lump. Complications may include ovarian torsion, testicular torsion, or hydrops fetalis. They are a type of germ cell tumor (a tumor that begins in the cells that give rise to sperm or eggs). They are divided into two types: mature and immature. Mature teratomas include dermoid cysts and are generally benign. Immature teratomas may be cancerous. Most ovarian teratomas are mature. In adults, testicular teratomas are generally cancerous. Definitive diagnosis is based on a tissue biopsy. Treatment of coccyx, testicular, and ovarian teratomas is generally by surgery. Testicular and immature ovarian teratomas are also frequently treated with chemotherapy. Teratomas occur in the coccyx in about one in 30,000 n ...

Miraculous Births
Stories of miraculous births often include conceptions by miraculous circumstances and features such as intervention by a deity, supernatural elements, astronomical signs, hardship or, in the case of some mythologies, complex plots related to creation. Near Eastern mythology The Assyrian and Babylonian concept of origins expressed procreation first in “relationships between gods and goddesses resulting in other gods and goddesses", such as Ea and Damkina assisted by Apsu giving birth to Marduk. The Akkadian '' Enûma Eliš'' describes the birth of Marduk as follows: "Ea, having overheard the plan of the primordial deities to destroy the other gods, deceived Apsu and Mummu and put them to death. 'Ea, his triumph over his enemies secured, in his sacred chamber in profound peace he rested.' (ANET, p. 61, lines 74—75.) Then he took over the place which Apsu had used for his cult and dwelt there with his spouse, Damkina." It was here that Marduk, the "most potent and ...

2012 Non-fiction Books
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asexual Reproduction
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent and thus the newly created individual is genetically and physically similar to the parent or an exact clone of the parent. Asexual reproduction is the primary form of reproduction for single-celled organisms such as archaea and eubacteria, bacteria. Many Eukaryote, eukaryotic organisms including plants, animals, and Fungus, fungi can also reproduce asexually. In vertebrates, the most common form of asexual reproduction is parthenogenesis, which is typically used as an alternative to sexual reproduction in times when reproductive opportunities are limited. Komodo dragons and some monitor lizards can also reproduce asexually. While all prokaryotes reproduce without the formation and fusion of gametes, m ...
