Answer:
a. growing cities in the East
b.new railroads and refrigerated cars.
c.barbed-wire fences
Explanation:
The 1800s were a period of discovering economic potentials in the United States that saw many ventures being initiated. Coupled with new technologies, theses ventures such as meat production and mining, saw profits increase and became big businesses.
Cattle for example experienced a massive growth that was brought by the cities in the east growing in size and demanding more meat to feed their populations. This demand coupled with new railroads and refrigerated cars meant that the meat could be transported long distances to these cities without worrying about them getting spoiled.
Also, with improvements in barbed-wire technology, land-owning ranchers could prevent other livestock from grazing on their fields while they themselves allowed theirs to graze. This led to cows eating healthier and therefore having more meat.
Mary would start with a hypothesis such as, "I believe that plants with no soil will not grow because there are no nutrients coming from the soil for the plant to grow"
Then she would put the plan in place to start her experiment. She will get the same type of seeds, the same amount of water and sunlight. The only difference between the 3 plants is that one plant will have no soil, the second plant will have 1 inch of soil, the third plant will have the correct amount of soil.
She will run the experiment for 2 weeks to see whether the plants have grown and what the conclusion is. She will record how much the plants have grown every day, she will measure the height of each plant.
At the end of 2 weeks, she will gather all her data and come to a conclusion.
They wanted more power for state governments.
