Which of the following occur as a result of inhibiting the release of chemical mediators of inflammation shortly after injury in a tissue? (1) stimulation of pain receptors (2) reduced stimulation of pain receptors (3) increased permeability of blood vessels (4) reduced permeability of blood vessels (5) edema (6) reduced redness

(2) reduced stimulation of pain receptors

(4) reduced permeability of blood vessels

(6) reduced redness

Explanation:

Chemical mediators released just after the injury cause stimulation of pain receptors , edema and increased permeability of the blood vessels. In this case, we are inhibiting the release of chemical mediators so no such actions would be observed.

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.

explanation:

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
