Mole (animal)
Moles are small, fossorial, subterranean mammals. They have cylindrical bodies, velvety fur, very small, inconspicuous eyes and ears, reduced hindlimbs, and short, powerful forelimbs with large paws adapted for digging. The word "mole" most commonly refers to many species in the family Talpidae (which are named after the Latin word for mole, ''talpa''). True moles are found in most parts of North America, Europe (except for Ireland) and Asia. Other mammals referred to as moles include the African Golden mole, golden moles and the Australian Marsupial mole, marsupial moles, which have a similar ecology and lifestyle to true moles but are unrelated. Moles may be viewed as pests to gardeners, but they provide positive contributions to soil, gardens, and ecosystems, including soil aeration, feeding on slugs and small creatures that eat plant roots, and providing prey for other wildlife. They eat earthworms and other small invertebrates in the soil. Terminology In Middle English, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vole
Voles are small rodents that are relatives of lemmings and hamsters, but with a stouter body; a longer, hairy tail; a slightly rounder head; smaller eyes and ears; and differently formed molars (high-crowned with angular cusps instead of low-crowned with rounded cusps). They are sometimes known as meadow mice or field mice. Vole species form the subfamily Arvicolinae with the lemmings and the muskrats. There are approximately 155 different vole species. Description Voles are small rodents that grow to , depending on the species. Females can have five to ten litters per year, though with an average lifespan of three months and requiring one month to adulthood, two litters is the norm. Gestation lasts for three weeks and the young voles reach sexual maturity in a month. As a result of this biological exponential growth, vole populations can grow very large within a short time. One mating pair can produce 100 offspring every year. Voles outwardly resemble several other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognates
In historical linguistics, cognates or lexical cognates are sets of words that have been inherited in direct descent from an etymological ancestor in a common parent language. Because language change can have radical effects on both the sound and the meaning of a word, cognates may not be obvious, and it often takes rigorous study of historical sources and the application of the comparative method to establish whether lexemes are cognate. Cognates are distinguished from loanwords, where a word has been borrowed from another language. Name The English term ''cognate'' derives from Latin , meaning "blood relative". Examples An example of cognates from the same Indo-European root are: ''night'' ( English), ''Nacht'' ( German), ''nacht'' ( Dutch, Frisian), ''nag'' (Afrikaans), ''Naach'' ( Colognian), ''natt'' ( Swedish, Norwegian), ''nat'' ( Danish), ''nátt'' ( Faroese), ''nótt'' ( Icelandic), ''noc'' ( Czech, Slovak, Polish), ночь, ''noch'' ( Russian), ноќ, ''no ...

Thumb
The thumb is the first digit of the hand, next to the index finger. When a person is standing in the medical anatomical position (where the palm is facing to the front), the thumb is the outermost digit. The Medical Latin English noun for thumb is ''pollex'' (compare ''hallux'' for big toe), and the corresponding adjective for thumb is ''pollical''. Definition Thumb and fingers The English word ''finger'' has two senses, even in the context of appendages of a single typical human hand: 1) Any of the five terminal members of the hand. 2) Any of the four terminal members of the hand, other than the thumb. Linguistically, it appears that the original sense was the first of these two: (also rendered as ) was, in the inferred Proto-Indo-European language, a suffixed form of (or ), which has given rise to many Indo-European-family words (tens of them defined in English dictionaries) that involve, or stem from, concepts of fiveness. The thumb shares the following with each of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polydactyl
Polydactyly is a birth defect that results in supernumerary body part, extra fingers or toes. The hands are more commonly involved than the feet. Extra fingers may be painful, affect self-esteem, or result in clumsiness. It is associated with at least 39 genetic mutations. It may either present alone or with other defects. Cases may run in families. The underlying mechanism involves an error in limb bud formation during early development. Diagnosis may occur before birth via prenatal ultrasound as early as nine weeks. X-rays may be useful after a child is a year old. The opposite is oligodactyly (fewer fingers or toes). Treatment varies from removal by cautery to more involved surgery. While putting a tight band around the base has been carried out, this is not typically recommended. If surgery is required, this is often done around two years of age. Occasionally multiple surgeries are required. Polydactyly is present in about 4 to 12 per 10,000 newborns. It is the most com ...

Ligand (biochemistry)
In biochemistry and pharmacology, a ligand is a substance that forms a complex with a biomolecule to serve a biological purpose. The etymology stems from Latin ''ligare'', which means 'to bind'. In protein-ligand binding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein. The binding typically results in a change of conformational isomerism (conformation) of the target protein. In DNA-ligand binding studies, the ligand can be a small molecule, ion, or protein which binds to the DNA double helix. The relationship between ligand and binding partner is a function of charge, hydrophobicity, and molecular structure. Binding occurs by intermolecular forces, such as ionic bonds, hydrogen bonds and Van der Waals forces. The association or docking is actually reversible through dissociation. Measurably irreversible covalent bonding between a ligand and target molecule is atypical in biological systems. In contrast to the definition o ...

Hemoglobin
Hemoglobin (haemoglobin, Hb or Hgb) is a protein containing iron that facilitates the transportation of oxygen in red blood cells. Almost all vertebrates contain hemoglobin, with the sole exception of the fish family Channichthyidae. Hemoglobin in the blood carries oxygen from the respiratory organs (lungs or gills) to the other tissues of the body, where it releases the oxygen to enable aerobic respiration which powers an animal's metabolism. A healthy human has 12to 20grams of hemoglobin in every 100mL of blood. Hemoglobin is a metalloprotein, a chromoprotein, and a globulin. In mammals, hemoglobin makes up about 96% of a red blood cell's dry matter, dry weight (excluding water), and around 35% of the total weight (including water). Hemoglobin has an oxygen-binding capacity of 1.34mL of O2 per gram, which increases the total blood oxygen capacity seventy-fold compared to dissolved oxygen in blood plasma alone. The mammalian hemoglobin molecule can bind and transport up to four ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swedish ( ) is a North Germanic languages, North Germanic language from the Indo-European languages, Indo-European language family, spoken predominantly in Sweden and parts of Finland. It has at least 10 million native speakers, making it the Germanic_languages#Statistics, fourth most spoken Germanic language, and the first among its type in the Nordic countries overall. Swedish, like the other North Germanic languages, Nordic languages, is a descendant of Old Norse, the common language of the Germanic peoples living in Scandinavia during the Viking Age. It is largely mutually intelligible with Norwegian language, Norwegian and Danish language, Danish, although the degree of mutual intelligibility is dependent on the dialect and accent of the speaker. Standard Swedish, spoken by most Swedes, is the national language that evolved from the Central Swedish dialects in the 19th century, and was well established by the beginning of the 20th century.

Norwegian Language
Norwegian ( ) is a North Germanic language from the Indo-European language family spoken mainly in Norway, where it is an official language. Along with Swedish and Danish, Norwegian forms a dialect continuum of more or less mutually intelligible local and regional varieties; some Norwegian and Swedish dialects, in particular, are very close. These Scandinavian languages, together with Faroese and Icelandic as well as some extinct languages, constitute the North Germanic languages. Faroese and Icelandic are not mutually intelligible with Norwegian in their spoken form because continental Scandinavian has diverged from them. While the two Germanic languages with the greatest numbers of speakers, English and German, have close similarities with Norwegian, neither is mutually intelligible with it. Norwegian is a descendant of Old Norse, the common language of the Germanic peoples living in Scandinavia during the Viking Age. Today there are two official forms of ''written'' ...

Danish Language
Danish (, ; , ) is a North Germanic languages, North Germanic language from the Indo-European languages, Indo-European language family spoken by about six million people, principally in and around Denmark. Communities of Danish speakers are also found in Greenland, the Faroe Islands, and the northern Germany, German region of Southern Schleswig, where it has minority language status. Minor Danish-speaking communities are also found in Norway, Sweden, the United States, Canada, Brazil, and Argentina. Along with the other North Germanic languages, Danish is a descendant of Old Norse, the common language of the Germanic peoples who lived in Scandinavia during the Viking Age, Viking Era. Danish, together with Swedish, derives from the ''East Norse'' dialect group, while the Middle Norwegian language (before the influence of Danish) and Bokmål, Norwegian Bokmål are classified as ''West Norse'' along with Faroese language, Faroese and Icelandic language, Icelandic.
