• osmotic pressures (n) about 6 bars lower,

• a bulk modulus of cell wall elasticity (s) about 50% lower.

We must note that cell wall elasticity is inversely related to s, i.e. the higher s the more elastic and the lower s the stiffer is the cell wall. With the relationship of

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
