Select a type of renewable energy. Compare it to fossil fuels by explaining two pros and two cons for its implementation on a large scale. Maintain an environmental focus (do not just give economic reasons).

Bio gas

Explanation:

Bio gas is gotten from the anaerobic breaking down of biomass especially animal waste.

PROS:

A. it is renewable: biogas is renewable and has an endless supply of material since animals are the main source when compared to fossil fuels.

B. It doesn't involve a rigorous mining exersice to get to like fossil fuels and it is in accessible abundance.

CON:

A. A lot of waste is needed for the product of biogas and the final waste (sludge) from the production process can be a huge problem to dispose off.

B. Some of the gases liberated in the manufacturing process are greenhouse gas, especially methane. These gases if let out, will contribute immensly to global warming.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
