How is energy from flowing water different from iron,petroleum or coal ?

Sati [7]3 years ago

The energy produced from flow of water or "Hydro-power" is different to energy produced from iron, petroleum and coal as it is a clean and renewable form of energy. Hydro-power is derived from the kinetic energy of the natural flow of water like in the case of a water mill whereas the other forms listed require combustion of the fuel source that produces harmful gases leaving a negative impact on the environment. Also, hydro-power is one of the cheapest forms of energy production.  
However, it should be noted that large-scale production of electrical energy from flowing water known as "Hydroelectric Power" uses man-made dams to store water in lakes as a source of potential energy. These dams can also have a negative impact on the environment as the natural flow of water is restricted. Some scientists also suggest that the construction of a dam leads to an increase in the number of earthquakes in and around the area of construction.

As a cell grows, what happens to its surface area to volume ratio? (hint: think of a balloon being blown up). how does this rati
iren [92.7K]
The surface area to volume ratio of the cell decreases.
This decrease is due to the fact that the volume of the cell increases at a greater rate than the surface surrounding the cell, the cell membrane, increases. This change is also visible when we are blowing up a balloon. 

When considering the cell division, the ratio remains roughly the same. It is advantageous for the cell to preserve its surface area to volume ratio, since a higher ratio means that substances are able to diffuse into and out of the cell at a fairly higher rate.

Tomtit [17]

Answer: SECONDARY CELL WALL.

Explanation: When cell wall grow,it becomes thickened,then it further deposits new layers of a different material (different from that of the primary cell wall) from where secondary cell wall is formed.

This secondary cell wall is made up of cellulose,hemicellulose,and lignin.

They function in providing additional strength,support, rigidity to cells and the larger plant.
