While Lamb's analysis assumed a straight wavefront, it has been shown [8] that the same characteristic equations apply to cylindrical plate waves (i.e. waves propagating outwards from a line source, the line lying perpendicular to the plate). The difference is that whereas the "carrier" for the straight wavefront is a sinusoid, the "carrier ...
A cross-bred ewe suckles her lamb, which was the first of the 2008 spring lambing at a farm in Coventry, England Domesticated sheep are herd animals that are bred for agricultural trade. A flock of sheep is mated by a single ram , which has either been chosen by a farmer or, in feral populations, has established dominance through physical ...
The exact line of descent from wild ancestors to domestic sheep is unclear. [2] The most common hypothesis states that Ovis aries is descended from the Asiatic (O. gmelini) species of mouflon; the European mouflon (Ovis aries musimon) is a direct descendant of this population. [3]
In asexual reproduction, a propagule is often a stem cutting. In some plants, a leaf section or a portion of root can be used. In sexual reproduction, a propagule is a seed or spore. In micropropagation, a type of asexual reproduction, any part of the plant may be used, though it is usually a highly meristematic part such as root and stem ends ...
Poddy lamb, bottle lamb or pet lamb – an orphan lamb reared on a bottle. Also cade lamb, or placer. Rubbed wool indicating the presence of external parasites on sheep. Pour-on – see backliner. Raddle – coloured pigment used to mark sheep for various reasons, such as to show ownership, or to show which lambs belong to which ewe. May be ...
The cell plate grows outward from the center of the cell to the parental plasma membrane with which it will fuse, thus completing cell division. Formation and growth of the cell plate is dependent upon the phragmoplast, which is required for proper targeting of Golgi-derived vesicles to the cell plate.
The cell plate will transform into the new cell wall once cytokinesis is complete. The phragmoplast is a plant cell specific structure that forms during late cytokinesis . It serves as a scaffold for cell plate assembly and subsequent formation of a new cell wall separating the two daughter cells.
A mammal (from Latin mamma 'breast') [1] is a vertebrate animal of the class Mammalia (/ m ə ˈ m eɪ l i. ə /).Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones.
