Silver Marten Rabbit
The Silver Marten is a breed of domestic rabbit. Although they are raised to compete in animal show, pet shows and agricultural shows, they are also regarded as "loveable and charming" pets. Description The Silver Marten is a medium-sized rabbit that weighs between 6.5 and 8.5 lbs. when fully grown. They are hardy and have fur that is described as soft "with a beautiful polished look to it". While more timid than some larger breeds of rabbit, they are still considered an excellent pet. The Silver Marten is playful, enjoys romping around, and likes playthings it can toss around its cage. History Early breeders of Chinchilla rabbits, a breed listed as critical on the American Livestock Breeds Conservancy Conservation Priority List, attempted to improve Chinchilla rabbits' color and pattern by introducing black and tan bloodlines. These genes later manifested as black "sports" described as "strange little black rabbits" as well as similar silver rabbits among standard Ch ...

Litter (zoology)
A litter is the live birth of multiple offspring at one time in animals from the same mother and usually from one set of parents, particularly from three to eight offspring. The word is most often used for the offspring of mammals, but can be used for any animal that gives birth to multiple young. In comparison, a group of eggs and the offspring that hatch from them are frequently called a clutch, while young birds are often called a brood. Animals from the same litter are referred to as litter-mates. Litter A species' average litter size is generally equal to one half of the number of teats and the maximum litter size generally matches the number of teats. Not all species abide by this rule, however. The naked mole rat, for example, averages roughly eleven young per birth and has eleven teats. Animals frequently display grouping behavior in herds, swarms, flocks, or colonies, and these multiple births derive similar advantages. A litter offers some protection from predation, not ...

Molt
In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is the manner in which an animal routinely casts off a part of its body (often, but not always, an outer layer or covering), either at specific times of the year, or at specific points in its life cycle. In medieval times it was also known as "mewing" (from the French verb "muer", to moult), a term that lives on in the name of Britain's Royal Mews where the King's hawks used to be kept during moulting time before becoming horse stables after Tudor times. Moulting can involve shedding the epidermis (skin), pelage (hair, feathers, fur, wool), or other external layer. In some groups, other body parts may be shed, for example, the entire exoskeleton in arthropods, including the wings in some insects. Examples In birds In birds, moulting is the periodic replacement of feathers by shedding old feathers while producing new ones. Feathers are ...

Sepia (color)
Sepia is a reddish-brown color, named after the rich brown pigment derived from the ink sac of the common cuttlefish ''Sepia''. The word ''sepia'' is the Latinized form of the Greek σηπία, ''sēpía'', cuttlefish. In the visual arts Sepia ink was commonly used for writing in Greco-Roman civilization. It remained in common use as an artist's drawing material until the 19th century. Grisaille is a painting technique developed in the 14th century in which a painting is rendered solely in tones of gray, sepia, or dark green. In the last quarter of the 18th century, Professor Jacob Seydelmann of Dresden developed a process to extract and produce a concentrated form of sepia for use in watercolors and oil paints. Sepia toning is a chemical process used in photography which changes the appearance of black-and-white prints to brown. The color is now often associated with antique photographs. Most photo graphics software programs and many digital cameras include a sepia tone filte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunlight
Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon. When direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat. When blocked by clouds or reflected off other objects, sunlight is diffused. Sources estimate a global average of between 164 watts to 340 watts per square meter over a 24-hour day; this figure is estimated by NASA to be about a quarter of Earth's average total solar irradiance. The ultraviolet radiation in sunlight has both positive and negative health effects, as it is both a requisite for vitamin D3 synthesis and a mutagen. Sunlight takes about 8.3 minutes to reach Earth from the surface of the Sun. A photon starting at the center of the Sun and changing direction eve ...

Candy
Candy, also called sweets (British English) or lollies (Australian English Australian English (AusE, AusEng, AuE, AuEng, en-AU) is the set of varieties of the English language native to Australia. It is the country's common language and ''de facto'' national language; while Australia has no official language, Engli ..., New Zealand English), is a Confectionery, confection that features sugar as a principal ingredient. The category, called ''sugar confectionery'', encompasses any sweet confection, including chocolate, chewing gum, and sugar candy. Vegetable, Vegetables, fruit, or Nut (fruit), nuts which have been glaze (cooking technique), glazed and coated with sugar are said to be ''Candied fruit, candied''. Physically, candy is characterized by the use of a significant amount of sugar or sugar substitutes. Unlike a cake or loaf of bread that would be shared among many people, candies are usually made in smaller pieces. However, the definition of candy also depends ...

Milk Chocolate
Milk chocolate is a solid chocolate confectionery containing cocoa, sugar and milk. Chocolate was originally sold and consumed as a beverage in pre-Columbian times, and upon its introduction to Western Europe. Major milk chocolate producers include Ferrero, Hershey, Mondelez, Mars and Nestlé. Between them, they are responsible for over half of the chocolate sold worldwide. Although four-fifths of all milk chocolate is sold in the United States and Europe, increasingly large amounts are consumed in China and Latin America. While taste and texture have been key to its success, milk chocolate has also historically been promoted as a healthy food, particularly for children. Recent evidence has shown that it may provide antioxidant health benefits. The word ''chocolate'' arrived in the English language about 1600, but initially described dark chocolate. The first use of the term "milk chocolate" was for a beverage brought to London from Jamaica in 1687, but it was not until the Sw ...

Eyes
Eyes are organs of the visual system. They provide living organisms with vision, the ability to receive and process visual detail, as well as enabling several photo response functions that are independent of vision. Eyes detect light and convert it into electro-chemical impulses in neurons (neurones). In higher organisms, the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain. Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in molluscs, chordates and arthropods. The most simple eyes, pit eyes, ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hair
Hair is a protein filament that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types, and hair care, but hair is also an important biomaterial primarily composed of protein, notably alpha-keratin. Attitudes towards different forms of hair, such as hairstyles and hair removal, vary widely across different cultures and historical periods, but it is often used to indicate a person's personal beliefs or social position, such as their age, sex, or religion. Overview The word "hair" usually refers to two distinct structures: #the part beneath the skin, called the hair follicle, or, when pulled from the skin, the bulb or root. This organ is located in the dermis and maintains stem cells, which not only re-grow the hair after it falls out, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Rabbit Breeders' Association
The American Rabbit Breeders Association (ARBA) is a national club for domestic rabbit and cavy breeders. The ARBA is headquartered in Knox, Pennsylvania in the United States. Its membership is composed of rabbit and cavy breeders throughout, fanciers, and pet owners in North America and many countries throughout the world. The ARBA serves to promote the domestic rabbit and cavy fancy, as well as commercial rabbit production. The American Rabbit Breeders Association sets official breed standards for recognized rabbit breeds and cavy breeds. Every five years the ARBA publishes a detailed guide entitled ''Standard of Perfection''. This guide is beneficial to rabbit and cavy (guinea pig) breeders, providing a reference to those interested in understanding the conformation standard for the variety of breeds recognized by the ARBA. ARBA recognizes 50 breeds of rabbit and 13 cavy breeds. Rabbit shows The ARBA sanctions rabbit shows throughout the year, all over the USA and Canada. Th ...

Mutation
In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other forms of repair, or cause an error during replication (translesion synthesis). Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce detectable changes in the observable characteristics (phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity. Mutation is the ultimate source o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breed
A breed is a specific group of domestic animals having homogeneous appearance (phenotype), homogeneous behavior, and/or other characteristics that distinguish it from other organisms of the same species. In literature, there exist several slightly deviating definitions. Breeds are formed through genetic isolation and either natural adaptation to the environment or selective breeding, or a combination of the two. Despite the centrality of the idea of "breeds" to animal husbandry and agriculture, no single, scientifically accepted definition of the term exists. A breed is therefore not an objective or biologically verifiable classification but is instead a term of art amongst groups of breeders who share a consensus around what qualities make some members of a given species members of a nameable subset. Another point of view is that a breed is consistent enough in type to be logically grouped together and when mated within the group produce the same type. When bred together, ind ...
