The Interpolation Theory suggests that the sporophyte generation progenated from a haploid, green algal thallus in which repeated mitot... |

https://en.wikipedia.org/wiki/Zero%20divisor | In abstract algebra, an element of a ring is called a left zero divisor if there exists a nonzero in such that , or equivalently if the map from to that sends to is not injective. Similarly, an element of a ring is called a right zero divisor if there exists a nonzero in such that . This is a partial case ... |

https://en.wikipedia.org/wiki/Spermosphere | In plant science, the spermosphere is the zone in the soil surrounding a germinating seed. This is a small volume with radius perhaps 1 cm but varying with seed type, the variety of soil microorganisms, the level of soil moisture, and other factors. Within the spermosphere a range of complex interactions take place amo... |
https://en.wikipedia.org/wiki/Carotid%20canal | The carotid canal is a passage in the petrous part of the temporal bone of the skull through which the internal carotid artery and its internal carotid (nervous) plexus pass from the neck into (the middle cranial fossa of) the cranial cavity.
Structure
The carotid canal is located within the middle cranial fossa, at ... |
https://en.wikipedia.org/wiki/Extension%20%28predicate%20logic%29 | The extension of a predicatea truth-valued functionis the set of tuples of values that, used as arguments, satisfy the predicate. Such a set of tuples is a relation.
Examples
For example, the statement "d2 is the weekday following d1" can be seen as a truth function associating to each tuple (d2, d1) the value true or... |
https://en.wikipedia.org/wiki/Inverse%20curve | In inversive geometry, an inverse curve of a given curve is the result of applying an inverse operation to . Specifically, with respect to a fixed circle with center and radius the inverse of a point is the point for which lies on the ray and . The inverse of the curve is then the locus of as runs over . The ... |

https://en.wikipedia.org/wiki/Gauss%27s%20law%20for%20magnetism | In physics, Gauss's law for magnetism is one of the four Maxwell's equations that underlie classical electrodynamics. It states that the magnetic field has divergence equal to zero, in other words, that it is a solenoidal vector field. It is equivalent to the statement that magnetic monopoles do not exist. Rather than... |
https://en.wikipedia.org/wiki/Potential%20natural%20vegetation | In ecology, potential natural vegetation (PNV), also known as Kuchler potential vegetation, is the vegetation that would be expected given environmental constraints (climate, geomorphology, geology) without human intervention or a hazard event.
The concept was developed in the mid 1950s by phytosociologist Reinhold T... |
https://en.wikipedia.org/wiki/Zoll%20surface | In mathematics, particularly in differential geometry, a Zoll surface, named after Otto Zoll, is a surface homeomorphic to the 2-sphere, equipped with a Riemannian metric all of whose geodesics are closed and of equal length. While the usual unit-sphere metric on S2 obviously has this property, it also has an infinite... |
