From these conclusions about plants and animals, two of the three tenets of cell theory were postulated. 1. All living organisms are composed of one or more cells 2. The cell is the most basic unit of life. Schleiden's theory of free cell formation through crystallization was refuted in the 1850s by Robert Remak, Rudolf Virchow, and Albert ...
The strong cosmic censorship hypothesis asserts that, generically, general relativity is a deterministic theory, in the same sense that classical mechanics is a deterministic theory. In other words, the classical fate of all observers should be predictable from the initial data.
Image from his textbook The Cell in Development and Inheritance, second edition, 1900. Edmund Beecher Wilson (October 19, 1856 – March 3, 1939) [2] was a pioneering American zoologist and geneticist. He wrote one of the most influential textbooks in modern biology, The Cell. [3] [4] He discovered the chromosomal XY sex-determination system in ...
It was mainly because of his friendship and correspondence with Schultze that Müller to some extent was able to follow the debate in Europe about Darwin's theory of evolution. Schultze periodically sent him scientific literature, among which was Darwin's On the Origin of Species , and a small microscope manufactured in Berlin, by Friedrich ...
The original theory by Lynn Margulis proposed an additional preliminary merger, but this is poorly supported and not now generally believed. [1] Symbiogenesis (endosymbiotic theory, or serial endosymbiotic theory [2]) is the leading evolutionary theory of the origin of eukaryotic cells from prokaryotic organisms. [3]

The novel would be an experiment where the author could discover and analyze the forces, or scientific laws, that influenced behavior, and these included emotion, heredity, and environment. The movement largely traces to the theories of French author Émile Zola .
Within the 20-year timespan, many scientists have actively contributed to examining and reevaluating Hager's acid-growth hypothesis. Despite the accumulation of observations that evidently identify the final target of the auxin-induced action to be H +-ATPase, which excretes H + protons to the apoplast and take in K + ions through its rectifying K + channel in the following years, the ...
