Answer:
Hi,
The correct answer option is a. deep sea corals
Explanation:
Deep sea corals are organism that habit the deeper and dark parts of the ocean and survive by feeding on tiny organisms washed by currents to obtain nutrients and energy.A major characteristics of these organisms is that they grow very slowly. Fishing practices such as dragging the sea floor with heavy fishing equipment and machines can destroy the homes of these organisms (coral gardens) thus affecting even the other organisms that live among them.
Best of Luck!
A biggie: the transcontinental railroad. Because it would economically improve wherever it was, both the North and the South competed for the railroad to be in their respective territory, evidenced by the Kansas-Nebraska Act and the Gadsen Purchase and induction of California as a free state in 1860.
In addition: people could get land cheap because it was abundant and might leave to start afresh economically.
There's other stuff I can't remember as clearly, but there's a little and I hope it helps :)
