Damask. Damask ( /ˈdæməsk/; Arabic: دمشق) is a woven, reversible patterned fabric. Damasks are woven by periodically reversing the action of the warp and weft threads. [ 1] The pattern is most commonly created with a warp-faced satin weave and the ground with a weft-faced or sateen weave. [ 2] Fabrics used to create damasks include silk ...
An aphid giving viviparous birth, an unusual mode of reproduction among insects. In animals, viviparity is development of the embryo inside the body of the mother, with the maternal circulation providing for the metabolic needs of the embryo's development, until the mother gives birth to a fully or partially developed juvenile that is at least metabolically independent.
Vivipary. Watsonia meriana, near the end of flowering, has cormlets that eventually drop and root. Red mangrove seeds germinate while still on the parent tree. In plants, vivipary occurs when seeds or embryos begin to develop before they detach from the parent. Plants such as some Iridaceae and Agavoideae grow cormlets in the axils of their ...
Viviparus. Viviparus, commonly known as the river snails, is a genus of large, freshwater snails with an operculum, aquatic gastropod molluscs. [2] They are primitive members of the clade Caenogastropoda. The old name of the genus was Paludina .
Lacerta vivipara Lichtenstein, 1823. The viviparous lizard, or common lizard, ( Zootoca vivipara, formerly Lacerta vivipara) is a Eurasian lizard. It lives farther north than any other species of non-marine reptile, and is named for the fact that it is viviparous, meaning it gives birth to live young (although they will sometimes lay eggs ...
Traditional modes. The three traditional modes of reproduction are: [ 1] Oviparity, taken to be the ancestral condition, where either unfertilised oocytes or fertilised eggs are spawned. [ 1] Viviparity, including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of ...
The height of the shell is 25–35 mm. The width of the shell is 20–26 mm. Males are 2 mm smaller than females of the same age. The shell colour is dark greenish brown or greyish yellow, with three reddish brown spiral bands. The shell is striated but has no hammer pattern. The shell apex is blunt (more pointed in other Viviparus species).
The earliest archeological evidence of fabric clothing is inferred from representations in figurines in the southern Levant dated between 11,700 and 10,500 years ago. [42] The surviving examples of woven cloth are linen from Egypt dated 5,000 BCE, although knotted or twisted flax fibers have been found as early as 7000 BCE. [43]
