diffusion of “holes” (minute regions in which theelectrical chargepotential is positive) through asemiconductor, and the diffusion of calcium through bone tissue in living organisms. Einstein’s theory of Brownian motion Since higher temperatures also led to more-rapid Brownian motion, in 1877 it...
Toxic wastes may be disposed of by usingbioremediationprocesses, in which living organisms are added to the waste to degrade organically or transform contaminants or to reduce them to environmentally safe levels. Some microorganisms use oil as a source of food, producingcompoundsthat can emulsify oil...
Facilitated diffusion is the transport of molecules from the region of higher concentration to the region of lower concentration with the help of carriers.
Diffusion is the process wherein the molecules move from a region of higher concentration to a region of lower concentration down the concentration gradient.
The inside of a leaf and its external environment are coupled by the stomata, microscopic pores in the leaf surface that can change under different environmental conditions and are controlled by the plant. If these stomatal openings are relatively large, resistance to molecular diffusion is low —...
What is an original mathematical example of juxtaposition? What is the difference between Brownian motion and diffusion? Define/explain the following term and give an example and non-example. Vector space Give an example of weak equivalence which is not a homotopy equivalence. ...
Photosynthesisis a physio-chemical process carried out by photo-auto-lithotrophs by convertinglight energyintochemical energy. Among the endless diversity of living organisms in the world,producersare a unique breed. Unlikeconsumers(herbivores,carnivores,omnivores, ordecomposers) that rely upon other living...
In this paper, the direct doping of a furanone into the epoxy resin matrix allowed an active slow diffusion and AF effect through the polymer matrix. Measurements to characterise the release of furanone from the matrix were not performed in this study. However, other researchers found epoxy ...
include blood, bone, adipose, tendons, and ligaments. In humans, cranial bones derive from the ectoderm, but the other connective tissues come from the mesoderm. Functions of connective tissue include shaping and supporting organs and the body, allowing body movement, and providing oxygen diffusion...
(by living organisms) andinformation processing(by such devices as electronic computers). Indeed, it is from this information-processing approach that some of the more intriguing theoretical contributions (e.g., abstract models of perception) are currently being made. It is expected that such ...
