Describes how energy is produced from the power of water. In your answer, include the terms: ocean water, turbine, electricity,
lapo4ka [179]

Most hydroelectric power plants have a dam and a reservoir. These structures may obstruct fish migration and affect their populations. Operating a hydroelectric power plant may also change the water temperature and the river's flow. These changes may harm native plants and animals in the river and on land. Reservoirs may cover people's homes, important natural areas, agricultural land, and archaeological sites. So building dams can require relocating people. Methane, a strong greenhouse gas, may also form in some reservoirs and be emitted to the atmosphere. Reservoir construction is "drying up" in the United States  Gosh, hydroelectric power sounds great -- so why don't we use it to produce all of our power? Mainly because you need lots of water and a lot of land where you can build a dam and reservoir, which all takes a LOT of money, time, and construction. In fact, most of the good spots to locate hydro plants have already been taken. In the early part of the century hydroelectric plants supplied a bit less than one-half of the nation's power, but the number is down to about 10 percent today. The trend for the future will probably be to build small-scale hydro plants that can generate electricity for a single community.  As this chart shows, the construction of surface reservoirs has slowed considerably in recent years. In the middle of the 20th Century, when urbanization was occurring at a rapid rate, many reservoirs were constructed to serve peoples' rising demand for water and power. Since  Hydroelectric energy is produced by the force of falling water. The capacity to produce this energy is dependent on both the available flow and the height from which it falls. Building up behind a high dam, water accumulates potential energy. This is transformed into mechanical energy when the water rushes down the sluice and strikes the rotary blades of turbine. The turbine's rotation spins electromagnets which generate current in stationary coils of wire. Finally, the current is put through a transformer where the voltage is increased for long distance transmission over power lines.   Hydroelectric-power production in the United States and the world!

bacteria culture starts with 400 bacteria and grows at a rate proportional to its size. After 4 hours, there are 9000 bacteria.
yawa3891 [41]

Answer:

A) P = P_0 e^{rt}

B) 19564

C) 5.5 or 6 hours

Explanation:

A) The formula that can be used for bacteria after "t" hours is

P = P_0 e^{rt}

Where ,

P represents the population after "t" hours

P_0 represents the initial population.

r represents the rate of growth of population

t represents the time taken by the population to grow

B) Here let us first find the rate of population growth.

9000 = 400 * e^{r*4}\\3.11 = r* 4\\r = 0.778

Thus, the population of bacteria after 5 hours

P = 400 * e^{0.778 * 5} \\P = 400* 48.91\\P =  19564\\

C)

30000 = 400 * e^{0.778 * t) \\\\4.317 = 0.778 * t\\t = 5.549\\or t= 5.5 or 6

Skin and nerve cells have different appearances and characteristics from each other, although they contain the same DNA. Why? A.
meriva
I think the correct answer from the choices listed above is option A. Skin and nerve cells have different appearances and characteristics from each other, although they contain the same DNA because the genes expressed in inskin cells may not be expressed in nerve cells and vise versa.
