metamorphosis Also called transformation. 2. A change in the form and often habits of an animal during normal development after the embryonic stage. Metamorphosis includes, in insects, the transformation of a maggot into an adult fly and a caterpillar into a butterfly and, in amphibians, the changing of a tadpole into a frog. 3.

Allele Allele, also called allelomorph, any one of two or more genes that may occur alternatively at a given site (locus) on a chromosome. Alleles may occur in pairs, or there may be multiple alleles affecting the expression (phenotype) of a particular trait. If the paired alleles are the same, the organism is said to be homozygous for that trait; if they are different, the organism is heterozygous.

- type I induction. The essential difference between these two types of induction was as follows: In type I, characteristic of mature hypostomes, one or two pairs of tentacles invariably grow out from the host Fig. 1, 1-6. Lateral aspect of successive stages in the development of the bud of Pelmatohydra oligactis.

Xenon Xenon is a chemical element with symbol Xe and atomic number 54. It is a colorless, dense, odorless noble gas, that occurs in the Earth's atmosphere in trace amounts.he first excimer laser design used a xenon dimer molecule (Xe 2) as its lasing medium, and the earliest laser designs used xenon flash lamps as pumps. Xenon is also being used to search for hypothetical weakly interacting massive particles and as the propellant for ion thrusters in spacecraft.

Xenomorph The Xenomorph physical form varies wildly depending on its life stage, hive caste, age and host, with numerous genetic varieties existing whose origins are completely unknown, as well as varieties which have been genetically engineered by host species or genetically grown.

- (Dr. Girish Chandra). Metamorphosis is the transition during the life history of some animals from birth or hatching to the adult stage. Metamorphosis is considered an indirect form of development, in that a metamorphic animal passes through morphologically distinct stages before reaching the adult form.In contrast, higher animals undergo direct development in which young and old resemble one another except in size and sexual maturity.hyroid hormones function somewhat like the molting hormones of insects, in that an increase of their concentration relative to prolactin leads to metamorphosis of the larva into the adult. Prolactin functions somewhat like the juvenile hormones of insects, in that it tempers the action of the thyroid hormones.

Metamorphosis A dragonfly in its final moult, undergoing metamorphosis from its nymph form to an adult. Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.

- Xeroderma pigmentosum, which is commonly known as XP, is an inherited condition characterized by an extreme sensitivity to ultraviolet (UV) rays from sunlight.eurological abnormalities are also thought to result from an accumulation of DNA damage, although the brain is not exposed to UV rays. Researchers suspect that other factors damage DNA in nerve cells. It is unclear why some people with xeroderma pigmentosum develop neurological abnormalities and others do not.

What Is A Xenograft? According to MedicineNet.com The proper definition of a xenograft is a surgical graft of tissue from one species to an unlike species (or genus or family). For example, a graft from a baboon to a human is a xenograft. The prefix “xeno-” means foreign.

Xenon: the essentials Xenon around us. Xenon has no biological role. Xenon is a noble or inert gas present in the atmosphere to a small extent. Xenon is present in the Martian atmosphere to the extent of about 0.08 ppm.

- Hox is short for homeobox genes, which are a set of genes involved in limb formation and creating the embryonic body plan of many animals. Many hox genes are regulatory genes, which just means that they are genes whose products (mRNA and proteins) increase or decrease the expression level of other genes.

First LED Headlights Appear, Unleash Astonishing Styling Possibilities The first production cars to use LED headlights will be the Audi R8 and Lexus LS, with more on the way. LEDs last longer and use less power, but by far the most appealing aspect of these tiny lights: the styling possibilities, where they take up much less room and can be distributed on the front of the car in unusual ways.

Xenomorph Xenomorph prehistory, and especially their origin, is an enigma, one that has resulted in a number of competing theories among the limited scientific circle that has access to the classified materials pertaining to the species.

protists Xenophyophores are one-celled, multinucleate creatures found at depths of 800 to 6000 meters on the ocean floor. A characteristic feature of xenophyophores is that they construct a sort of artificial exoskeleton by gluing together particles of sediment and the microscopic shells of foraminifera.

Teleomorph, anamorph and holomorph 1 Anamorph: an asexual reproductive stage (morph), often mold-like. 2  When a single fungus produces multiple morphologically distinct anamorphs, these are called synanamorphs. 3  Holomorph: the whole fungus, including anamorphs and teleomorph.

What are the limits on a Metamorphmagus? In the Harry Potter books, Metamorphmagi are people with the innate ability to change their own shape at will. Tonks is the main example of a Metamorphmagus, and she is shown changing the shape of her nose, the colour and shape of her hair, and once even taking the form of an entirely different old lady.

- Allomorph In linguistics, an allomorph is a variant form of a morpheme, that is, when a unit of meaning varies in sound without changing meaning. The term allomorph explains the comprehension of phonological variations for specific morphemes.
