Answer:

D. Ecosystem

Explanation:

The living beings and the non-living conditions of a region interact with each other. They together make an ecosystem. In the given study, the aim was to restore the above-ground vegetation of the region. The "above ground vegetation" of the region is part of its biotic factors. The "below ground soil" is a component of the abiotic factors of the region. Since the study focused on both biotic and abiotic factors of the region, it focused on the ecosystem.

Which of these is least likely to be an adaptation of an organism to its environment?
Mkey [24]

Answer:

The correct answer is "C. Cave fish have evolved degenerated eyes because they have no use for vision in dark, underwater caves."

Explanation:

All of these statements about organism adaptation to its environment are true, but the real reason why cave-fish are blind is not because there's no use for their eyes in the dark, but because being blind saves them energy, as using one's vision requires the activity of photoreceptive cells and neurons, and underground caves are lacking in both food and oxygen.

Sympathetic neurons stimulate vasoconstriction in the gi tract, while sympathetic neurons stimulate vasodilation in arterioles s
Anvisha [2.4K]

It is because of the different neurotransmitters and their receptors.

Sympathetic stimulation of arterioles in skeletal muscle is mediated by epinephrine acting on its β-adrenergic receptors.  

Sympathetic stimulation   of vasoconstriction occurs as a result of activation of α-1 adrenergic receptors by norepinephrine released by post-ganglionic sympathetic neurons.
