•Address the letter to the editor of a local newspaper.
Julli [10]

The answer is; hydrothermal, geothermal, and wind

Hydrothermal, taped from the biggest river on the state contributes approximately 60% of the energy in the state. Geothermal is second,approximately 30% while wind power contributes approximately 10%.


The costs of the electricity in the state are relatively cheap compared with states whose main source of energy is hydrocarbon fuels.   Geothermal power is the cheapest (even though initial investment is prohibitive). Hydrothermal is slightly expensive than geothermal due to the maintenance required and also  is prone to fluctuations of the river regime. Winds are also cheap but initial investment if the wind farm is high.



Hydrothermal energy has the biggest environmental impact compared to the other two. Due to the walls of the dam on the river, migration of some aquatic species is impeded. The reduced flow of water (and sediments) downstream of the dam also impact these ecosystems. Geothermal and wind energy sources have a very minimal environmental impact on the environment .


The state could increase electronics with low power consumption (such as LED lights) in the market for availability to the population. This would be followed by a sensitization campaign on the ideal use of power in the household to conserve power when not in use.

Describe how the process of photosynthesis led to an increase in cellular respiration and more complex cells
koban [17]

Answer:

<u><em>BRIEF EXPLANATION</em></u>

Photosynthesis is the anabolic process of building up glucose and making O2 from CO2 and water while cellular respiration is the opposite catabolic process of breaking down glucose by oxidizing it with O2 to get CO2 and water.

Explanation:

<em><u>MAIN ANSWER TO THE QUESTION.</u></em>

Photosynthesis is like when you’re trying to gain muscle and you eat tuna and eggs to turn it into muscle tissue. This takes energy in the form of food just like how photosynthesis requires sunlight for energy.

Cellular respiration is like when impoverished people starve for a week because they don’t have sufficient food to eat for nutrients. They have to get them from somewhere else. So the body breaks down glycogen, body fat and muscle tissue to provide the energy.
