Explain the mechanism by which mechanical stimulation of the skin produces a flare?

As found on Page 504 of the Pearson Human Anatomy and Physiology Laboratory Manual 9th edition.
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".

Explain why a marsh provides an environment that produces biogas?
It's generated by decaying organic matter in the swamp.
What was the major weakness in Charles Darwin's theory during his life time?
The lack of a mechanism to explain how traits were passed to offspring intact when most believed inheritance worked through blending.
How did Charles Darwin explain the mechanism for evolution?
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.
Describe the pressure flow mechanism of sugar transport?
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."

Explain why the homeostatic mechanism of decreasing peripheral blood flow is critical to survive?
In cases of extreme trauma, such as blood loss, the body tries to preserve the internal organs by restricting peripheral blood flow.
