Answer:

Transcription is the process through which DNA is copied into mRNA

Explanation:

The transcription is the process that copies the DNA  in to mRNA. It is also referred as the initial step in the dual step process for protein synthesis, which happens inside the nucleus of the cell.  After transcription, the translation step happens. In this step i.e. transcription, the genetic materials are transferred to the mRNA. mRNA strand made is exactly similar to that of strand of DNA in transcription as the DNA requires a base strand for sequence.

Which of the following is not important in determining the distribution of organisms in aquatic biomes? A. light penetration B.
Vlada [557]

Answer: Option C) water

Explanation:

The factors affecting the distribution of organisms in aquatic biomes include:

- Light penetration: Plants life is limited to the upper layers of the ocean where light cab penetrate and be used to produce food. Thus, very few organisms are found in the ocean deep.

- Waves: the movement of surface water of the oceans, and it's direction affect the placement of organisms as they must have strong anchor or body parts suited for buoyancy

- salinity: not all organisms can survive in water with high salt content. Thus, some live in salty water, and others in fresh water or the mixture.

- Mineral content: the levels of hydrogen ion could make a water bidy alkaline or acidic thus affecting organism that can survive in it

Thus, since water ordinarilly is Universal, it is not an important factor in determining distribution of organisms in aquatic biomes

answer 1:

Environmental Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal, and light

Air Pollution

Water Pollution

Soil pollution

Noise pollution

Radioactive pollution

Light pollution

Humans are the main cause of water pollution, which is triggered in many ways: by the dumping of industrial waste; due to temperature rise, that cause the alteration of water by reducing the oxygen in its composition; Or due to deforestation, which causes sediments and bacteria to appear under the soil

Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles. Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result.

Effects:

Nutrient pollution can cause toxic algal blooms in drinking water sources that create toxins that kill fish and other aquatic animals. Direct exposure to this toxic alga causes serious health problems in humans including neurological effects, respiratory problems, stomach and liver illness, and rashes.

answer 2:

The Industrial Revolution brought rapid urbanization or the movement of people to cities. Changes in farming, soaring population growth, and an ever-increasing demand for workers led masses of people to migrate from farms to cities. Almost overnight, small towns around coal or iron mines mushroomed into cities.

anwer 3:

advantages are

1_A Fuel Supply That Never Runs Out

2_Zero Carbon Emissions

3_Cleaner Air and Water

4_A Cheaper Form of Electricity

5_Renewable Energy Creates New Jobs

disadvantages are

1_Higher Capital Costs

2_Electricity Production Can Be Unreliable

3_Energy Storage Is a Challenge

4_It’s Impacted by Environmental Conditions

5_Renewables Still Have a Carbon Footprint

anwer 4:

Hazardous waste can be treated by chemical, thermal, biological, and physical methods. Chemical methods include ion exchange, precipitation, oxidation and reduction, and neutralization. Among thermal methods is high-temperature incineration, which not only can detoxify certain organic wastes but also can destroy them.

answer 5:

You could do this by:

1_Try to stay away from disposable goods. In particular, paper plates, cups, bottles, and plastic utensils.
