The charcoal produced by the burning of the woods provides nutrients for reforestation.
Move three sodium ions out of a cell and two potassium ions into a cell while consuming an atp for each cycle
Explanation:
By pumping three (3) Na+ to the outside and two (2) K+ to the inside of the cell, there is a net positive charge on the outside leaving the inside of the cell electronegative. This process is achieved by the Na+/K+ pump and is a process that consumes ATP energy.
This is much more important in a neuron cell who ¾ of its energy is used to maintain a -70mV resting potential that is important for the nerve to pass impulse when depolarised.
In other cells, the gradient created in important in maintaining the homeostatic osmolarity inside the cell to avoid swelling and lysis of cells due to uptake of excess water by osmosis. The Na+ gradient is also used to import other molecules into the cell such as glucose and amino acids. These molecules are coupled with Na+ and then are absorbed efficiently as the Na+ flow back inside the cell down the Na+ concentration gradient.

A force is a push or a pull. When one object pushes or pulls another object, you say that the first object is exerting a force on the second object.
<span>Liquids have a medium shape and volume. The particles can move or slide past each other due to the small space available for movement. It cannot be compressed further due to the repulsive forces that act between them. The kinetic energy is medium too. These are the reason why liquids must be placed in a container or vessel to contain them. Beakers, Flasks, and graduated cylinders can contain the liquid. They are like glasses except they are shaped to achieve a specific measurement. Rulers cannot contain the liquid.</span>
Answer:
The cerebellum (back of the brain) and the brainstem (middle of the brain)
Explanation:
Muscle movement coordination can be<em> voluntary</em> or <em>involuntary</em>. There are different sections of the brain responsible for the two;
- Voluntary movement of muscles is coordinated by the brainstem in addition to other functions such as sneezing, swallowing, vomitting, etc.
- Involuntary coordination of muscles is controlled by the cerebellum in addition to maintaining posture, balance and body equilibrium.
Hence, both the cerebellum and the brainstem are responsible for coordinating muscle movement.
