In neurogenic shock, the characteristic mechanism is the reduction of sympathetic outflow from the brainstem leading to the decreased in the blood vessel tone and eventually vasodilation. In the presence of vasodilation, there will be decreased blood pressure and eventually shock. Since there is reduced sympathetic outflow, there will also be a decreased heart rate, warm skin (from the vasodilation), and dry skin (from the reduced cholinergic stimulation of the sweat glands).
<span>a. organisms that live in different ecosystems
- if they live in different ecosystems, they won't compete, wrong answer!
b. organisms that use the same resource
-this is the best answer! they would compete over this resource!
c. organisms that live in the same area
-this makes competition possible, but more aspect are needed, for example they need to want the same resource (if you only eat apples and y our friend only eats ants, you won't compete)
d. organisms that are classified in the same phylum
-no, they can for example live in different ecosystems!
