Fasciation (pronounced / ˌ f æ ʃ i ˈ eɪ ʃ ə n /, from the Latin root meaning "band" or "stripe"), also known as cresting, is a relatively rare condition of abnormal growth in vascular plants in which the apical meristem (growing tip), which normally is concentrated around a single point and produces approximately cylindrical tissue ...
A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point of the wave. When the crests and troughs of two sine waves of equal amplitude and frequency intersect or collide, while being in phase with each other, the result is called constructive ...
Spindrift is derived from the Scots language, but its further etymology is uncertain. [4] Although the Oxford English Dictionary suggests it is a variant of spoondrift based on the way that word was pronounced in southwest Scotland, [5] from spoon or spoom ("to sail briskly with the wind astern, with or without sails hoisted") and drift ("a mass of matter driven or forced onward together in a ...
The outcome is the rapid movement of the base of the wave up the swash slope and the disappearance of the wave crest. The front face and crest of the wave remain relatively smooth with little foam or bubbles, resulting in a very narrow surf zone, or no breaking waves at all. The short, sharp burst of wave energy means that the swash/backwash ...
The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home.. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
Advanced Placement (AP) Biology (also known as AP Bio) is an Advanced Placement biology course and exam offered by the College Board in the United States. For the 2012–2013 school year, the College Board unveiled a new curriculum with a greater focus on "scientific practices".
Oscillations are an important type of cell signaling characterized by the periodic change of the system in time. [1] Oscillations can take place in a biological system in a multitude of ways.
What Wagner calls "a fringe movement in evolutionary biology", [2] the form of structuralism exemplified by Brian Goodwin, [2] [21] effectively denies that natural selection is important, [2] [22] or at least that biological complexity could be reduced to natural selection. [22] [23] This led to conflict with Darwinists such as Richard Dawkins ...
