B. because the match contains phosphorus, and it is unlit, so it has chemical POTENTIAL energy
Yes they do have a cell wall
All matter is composed of protons, neutrons, and electrons. Therefore the answer is sodium.
Explanation:
The speed of water in a stream is affected by the gradient of the geography. The steeper the geography the higher the speed of the water flow and the higher the erosion capacity of the stream. This means the stream will be narrow and deep. There is also less meandering of the stream.
When the gradient is less steep, the stream flow slows down and so does the erosion force it bears especially on the river bed. This therefore result in a higher horizontal erosion than vertical erosion. The steam becomes wide and shallow. The stream is also more likely to meander.
The volume of water in the stream also affects the size, shape, and flow of streams and rivers. A higher volume of water has more erosion power due to the weight of the water column. The stream is, therefore, more likely to be bigger in size than a stream that carries low water volume.
