The redness or flare observed after mechanical stimulation of the skin results from a local inflammatory response promoted by chemical mediators released by injured tissues.
These mediators stimulate increased blood flow into the area and leaking of fluid (from the capillaries) into the local tissues.
Note about an extremely sensitive skin condition:
Dermatographism: a condition in which the direct line of stimulation will swell quite obviously is called a "wheal".
This results from a local inflammatory response promoted by chemical mediators released by injuries.

The lack of a mechanism to explain how traits were passed to offspring intact when most believed inheritance worked through blending.
He did not and could not. Charles Darwin's "On the Origin of Species" was published in late 1859, Mendel published "Experiments in Plant Hybridization" in 1865 (6 years later) which might have led Darwin into r question in this areas, but his theories were not widely embraced until the 1900s. Nucleic Acids were not studied completely until 1950s.Added:The mechanism for evolution is natural selection. Charles Darwin had trouble explaining the mechanism of heredity.
Phloem transports sugar in the vascular tissue system. In the ground tissue system, it is stored and includes mesophyll, where most photosynthesis occurs. Understanding this, I believe , sugar-flow mechanism or transpirational-pull mechanism; this would explain the mechanism of sugar transport. This is because "a vascular tissue called phloem, sends sugars from leaves or storage tissues to all parts of the plant."

in order to explain the mechanism of enzymes action a German chemist Emil fischer,in 184,proposed the lock and key model.According to this model both the enzymes and the substrate possess specific complementary geometric shapes that fit exactly into one another.This model explain enzyme specificity.
Explain the access mechanism of a Magnetic disk. How is this access mechanism different in RAID level 5?
it depends on the stimulation. if the stimulation is not strong enough, there might be no action potential. However, if the stimulation is strong enough, there will be an action potential

Explain how the mechanical advantage of a wheel and axle change as the size of the wheel increases?
explain the mechanism of diffusion in the separation of isotopic mixtures

Pulleys are considered part of the lever family because they operate on similar principles of transferring force. Pulleys use a wheel and axle system to redirect and amplify force, just like how levers use a rigid bar to do the same. Both pulleys and levers help make it easier to lift heavy objects by trading off force over distance.
Its a machine that harvests grain and pulse crops.
