An endospore is a dormant, tough, and non-reproductive structure produced by some bacteria in the phylum Bacillota. [1] [2] The name "endospore" is suggestive of a spore or seed-like form (endo means 'within'), but it is not a true spore (i.e., not an offspring). It is a stripped-down, dormant form to which the bacterium can reduce itself.
The location of an endospore within a cell is species-specific and can be used to determine the identity of a bacterium. Dipicolinic acid is a chemical compound which composes 5% to 15% of the dry weight of bacterial spores and is implicated in being responsible for the heat resistance of endospores.
The question of how humans would get to Mars was addressed in several ways: when not travelling there via spaceship as in the 1911 novel To Mars via the Moon: An Astronomical Story by Mark Wicks, [24] they might use a flying carpet as in the 1905 novel Lieut. Gullivar Jones: His Vacation by Edwin Lester Arnold, [14] [18] [20] a balloon as in A Narrative of the Travels and Adventures of Paul ...
Endospore staining is a technique used in bacteriology to identify the presence of endospores in a bacterial sample. [1] Within bacteria, endospores are protective structures used to survive extreme conditions, including high temperatures making them highly resistant to chemicals. [ 2 ]
The book includes experiments on plant stimuli using a polygraph, a method which was pioneered by Cleve Backster. [6] [7] Parts of the book attempt to disparage science, particularly plant biology, for example by claiming science is not concerned with "what makes plants live", in order to promote its own viewpoint that plants have emotions. The ...
He called it "an invaluable compendium of and contribution to fifty years of science fiction research", representing "a true conceptual breakthrough" for the field of science fiction studies, and noted that even more than the encyclopedia's previous edition, this one "is the one essential reference book for anyone interested in science fiction ...
