The dependent variable is the variable which can be manipulated and can affect the independent variable. The dependent variable is on the x-axis while the independent variable is placed on the y-axis. In this case, the x-axis is the number of weeks while the y-axis is the height of the plant.
Active transport. Which the molecules are transported by a protein called carrier protein with the help of ATP.
There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. P waves cause the ground to compress and expand, that is, to move back and forth, in the direction of travel.
Answer:
B. After clearcutting, plant uptake stopped and nitrogen accumulated in the soil.
Explanation: Clear cutting leaves the soil bare and allows for direct penetration of sunlight this increases the soil temperature which favors the activity of soil microrganism. This microrganism activity increase the production of ammonium and nitrate hence the increase in soil Nitrogen level. Clearcutting then allows for accumulation of Nitrogen produce due to removal of plant or forest tree that could use up the Nitrogen produced.
