Answer:
wall
Explanation:
It is composed of peptidoglycan. The wall gives the cell its shape and surrounds the cytoplasmic membrane, protecting it from the environment.
The Sun is the basic source of energy for the Earth which affect the growth of all living things and the Sun also affect the all the biochemical processes. We know that the amount of radiation from the Sun changes day by day due to the distance of the Earth from the Sun. The rate of Solar energy affects the Earth in two ways.
The rate of solar heating which directly affects the processes like the evaporation and condensation and indirectly it affects the cloud forming processes of the Earth. The rate at which the solar energy reaches the Earth is called as the Total Solar Irradiance or TSI. This affects the climate of the Earth in many ways.
The change in rate of cloud formation increases of decreases with the distance of the Sun from Earth and hence a warm, moderate or cold climate is formed
It also affects the formation of winds due to the low or high pressure in the water bodies and hence affect the climate in the coastal areas.
The tropical areas have hot and humid climate due to the equator which has maximum exposure to the Sun’s heat.
Hence, the Sun is one primary feature that affects the climate in the Earth.
The answer is Law of Dominance
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.
