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.

The question is incomplete as it does not have the option which are:

  • Favorable genes from parental generations provide advantageous characteristics to the hybrid species.
  • Hybridization produces offspring traits that allow different species to survive in extreme environments.
  • Inherited traits passed on from parental generations make hybrid species more susceptible to disease.
  • Hybrid species display more adaptation due to their reduced genetic diversity

Answer:

Favorable genes from parental generations provide advantageous characteristics to the hybrid species.

Explanation:

The white cattail is the plants which grow in the wetlands that are they are adapted to grow in the wetlands. The white cattail species in nature is the result of natural hybridization that is mixing of the genes of two different species of the same genus.

The white cattail can when grown in the Midwestern states well adapted to grow in that area and the reason for this could be accounted that the genes from the parental plants provided many advantages to the newly formed hybrid species.

Thus, the selected option is correct.
