Answer:
The correct answer is a. sympathetic nervous system.
Explanation:
The sympathetic nervous system involves the rapid involuntary response called fight and flight response during stress conditions. In a stressful condition, our body parts give signals to the hypothalamus which stimulates the sympathetic nervous system of the body.
The activated sympathetic nervous system then stimulates the release of a hormone called adrenalin and nor-epinephrine from the adrenal gland. These stress hormone together with neural activity give rise to fight and flight response.
During this response our mind becomes alter, breathing becomes deep, heart rate becomes high, pupil diabetes, and excess sweating occurs. Therefore the correct answer is a.
Answer:
The answer is option D "Succession rates would depend on the number of early arriving facilitator species"
Explanation:
Ecologists have a solid interest in knowing how communities structure and change over the long run. Indeed, they have invested a ton of energy seeing how complex communities, such as forests, emerge from void land or uncovered stone. They study, for instance, locales where volcanic eruptions, ice sheet retreats, or out of control fires have occurred, clearing land or uncovering rock.
In examining these destinations over the long haul, ecologists have seen steady cycles of progress in natural communities. As a rule, a community emerging in an upset territory experiences a succession of movements in synthesis, frequently throughout numerous years. This arrangement of changes is called natural succession.
Succession is a progression of reformist changes in the structure of an ecological community over the long run.
In primary succession, recently uncovered or recently shaped stone is colonized by living things unexpectedly.
In secondary succession, a territory recently involved by living things is upset then recolonized following the aggravation.
Answer:
D
