Soil samples from the forests were collected, sterilized, and populated with one or a combination of three types of soil organisms (the fungus Botrytis cinerea, the bacterium Escherichia coli, and the nematode Caenorhabditis elegans). The microcosms were then kept at the mean soil temperatures of...
Therefore, to produce the different dynamics, the models need not undergo any change in structure, such as might occur in different systems or groups of organisms. Here we show that field populations of a predator, the zooplanktonic herbivore Daphnia and its algal prey exhibit three qualitatively...
In addition, soil physicochemical properties make the partitioning of chemical activities of Pb highly uneven, which leads to a great difference in the Pb absorption efficiency of organisms6. Nowadays, there are many remediation technologies for heavy metals contaminated soil. Conventional techniques for...
Use of model organisms and in vitro techniques relevant to developmental biology and medicine are acceptable, as are translational human studies.doi:10.1203/00006450-198507000-00096Gupta, Radhey SMehta, Kamal DPediatric ResearchGUPTA, R.S., and MEHTA, K.D. (1986). Genetic and biochemical char- ...
1.Biological Taxonomy: One prominent example of categorization in nature is biological taxonomy. Organisms are classified into different categories based on their shared characteristics such as morphology, behavior, and genetic makeup. The Linnaean system is a widely used hierarchical classification system...
Type III secretion systems represent a class of secretion systems first found in pathogenic organisms[17], and they have homology to genes involved in secreting flagellar subunit proteins during flagellar biosynthesis. In contrast to flagellar genes, which are often constituitively active, the type II...

Insect) but also to red and green, and Vegetable and Insect entail a context called Organisms (Fig. 4 right). All relations between objects and representations are shown in the top left of Fig. 5. A matrix expression (Fig. 5 left below) is obtained if all lines between representations (...
In a diverse array of organisms, retinal development occurs in waves. The best example of this is in Drosophila melanogaster, in which the eye differentiates in a wave defined by the morphogenetic furrow [52]. Cells ahead of the furrow express genes involved in cell division and the undifferent...
