Answer - It will allow the molecules move against the concentration gradient which is pretty much acting against it. (Low concentration gradient TO high concentration)
Reason - It will use energy. For example in a river theres a down flow but if you want to get up top of the river you must go against it by going against the current. Pretty much the same thing but its happening with the cell in a active mode.

Answer:
Ice cores are cylinders of ice drilled from ice sheets/glaciers. ice cores tell scientists about temperature, volcanic activity, atmospheric composition, precipitation, and wind patterns.
Explanation:
the thickness of each layer in the core allow scientists to determine how much snow fell in the area during a particular year. the layers are formed by layers of different types of snow. During the summer, when it is light for 24 hours, the snow on the top layer changes texture. When winter arrives, it turns dark and cold again and more snow falls on top of the summer snow, creating distinct layers.
