<span>Prior to the standard gauge track, railroad travel was much more arduous and painstaking. There were originally several types of gauges used on a railway track. This caused long train trips to require multiple stops in order to change train cars. With the standard gauge track on trains in the 1800s, multiple changes were no longer necessary and so the trips were shorter.</span>
It would be 3/8 m/s because V= (xf-xi)/(tf-ti) so (7-4)/(8-0)= 3/8
Answer:
Option B. The lowlands is the region that labeled with the number 4 on the map presented in the question.
Explanation:
The Hudson Bay-Arctic Lowlands is a land-form region of Canada, located through the provinces of Ontario, Quebec, Manitoba, Yukon, Northwest Territories and Nunavut. The region was formed in the Paleozoic Era, when the weight of a glacier sunk the Canadian Shield and the area became a lowland due to the glaciers retreating.
The correct answer to this open question is the following.
Although the question does not include options, we can say the following.
This is a photograph of !Kung hunter-gatherers, a group of modern foragers. The study of the !Kung and other modern foragers as well as the geometry of ancient bones provide insight into whether people had to work harder to acquire their food as hunter-gatherers or as agriculturalists. The statements that correctly reflect related research findings are the following:
"There is a great deal of variation in how much both hunter-gatherers and agriculturalists work." And "bone signatures in Coastal Georgia indicate a lessened work load with the onset of agriculture."
For the !Kung, the work load heavily depended on the conditions of the environment. They had to consider their living conditions and necessities to know what to do and the way to work to fulfill their necessities. Researcher Christopher Ruff shared important knowledge about how bones found in the Coastal area show that these people had less stress due to the fact that their level of work and general activities were lower. The weather conditions of the region allowed them to grow crops and harvest successfully in the coastal region. Raw materials and natural resources were plenty in this area.
