Answer:

Stone

Explanation:

These houses are more like our houses than any others in the Stone Age. They had foundations and they were built of wood and wattle and daub (a mixture of manure, clay, mud and hay stuck to sticks). They were sometimes made of stones. The roofs were made of straw.

When NADH is the electron donor to the respiratory chain, 2.5 ATP are formed, but when FADH2 is the electron donor, only 1.5 ATP
Fofino [41]

Answer:NADH donates it electron to complex I a higher energy level than other complexes while FADH donates it electron to complex II a lower energy complex.

Explanation:

Both NADH and FADH are shuttle of high energy electrons originally extracted from food into the inner mitochondrial membrane.

NADH donate it electron to a flavoprotein consisting of FMN prosthetic group and an iron-sulphur protein in ETC complex-I. Two electrons and one hydrogen ion are are transferred from NADH to the flavin prosthetic group of the enzyme.

While the electrons from FADH2 enters the ETC (electron transport chain) at the level of co-enzyme Q (complex II). This step does not librate enough energy to act as a proton pump.

So NADH produces 2.5 ATP during the ETC and oxidative phosphorylation because it donates its electron to Complex I, which pump more electrons across the membrane than other complexes.

•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.
