Compare Rutherford’s model of the atom with Bohr’s model.

Put the events of cultural eutrophication in the correct order.

aleksandrvk [35]

Answer:

c. Increase in nutrient levels

b. Algal blooms

d. Algae dies, microbes decompose using oxygen

a. Dead zones (hypoxic zones)

Explanation:

The term eutrophication refers to the enrichment of surface water with nutrients. This process is related to human pollution activities.

Eutrophication is the biological process that generates in water by an oversupply of nutrients or organic matter. This matter, mainly compounded with nitrogen or phosphorous, favors the phytoplankton multiplication (microscopic plants growing on the water surface) and other aquatic plants. This overgrowth leads to an enhance in primary productivity.

Little by little begin sedimentation is caused by the death of some vegetable organisms that sink in the bottom. These sediments rich in organic matter suffer decomposition in the presence of oxygen.

When oxygen disappears, anaerobic bacteria act and produce fermentation.

On the surface, plants and phytoplankton keep growing, creating a mantle that impedes the light reach deeper areas. The phytoplankton overgrowth on the water surface and the fermentation processes in the bottom originate toxic compounds that damage the animals. Animals die, creating more sediments in the bottom where there are anaerobic conditions.

Decomposition and fermentation processes increase, producing a bad smell.

The result of eutrophication is the stratification of the water mass:

· First superficial layer, the overgrowth of blue-green algae, produces toxins and interrupts the pass of light to deeper areas. The surface then becomes warmer.

· The second layer might have oxygen available for the animals.

· In the third layer, there is no oxygen, so life is impossible for animals or plants.

· In the fourth layer, there are animals and plant remains in the process of sedimentation.

· At the bottom, there are organic matter and anaerobic bacteria in charge of decomposition and fermentation, through which they produce toxic gases and smell.

Why do we say that "an enzyme is reusable"?

Tanzania [10]

enzymes are resuable as they are biologically catalyst which speeds up the rate of a reaction without being chemically changed themselves. However, if the enzyme is to be denatured under unfavourable conditions (extreme temperatures, extreme pH), the enzymes may not be reusable once denatured.

Describe three clean coal technologies and how they can mitigate the environmental impacts of coal. Explain how they work and pr

Andrej [43]

Clean coal technology refers to a gathering of technologies being created in order to reduce the environmental influence of coal energy production and to mitigate global climate change. There are three distinct technological procedures accessible for the aim of capturing carbon as demanded by the clean coal concept:

1. Pre-combustion capture: This includes gasification of a feedstock like coal to generate gas that may be shifted to develop a mixture of carbon dioxide and hydrogen gas, from which the carbon dioxide can be effectively separated and captured, transported, and eventually sequestered.

2. Post-combustion capture: This is the capturing of carbon dioxide from the exhaust gases of combustion methods.

3. Oxy-fuel combustion: The fossil fuels like coal are combusted in a mixture of oxygen and recirculated flue gas, rather than in air that hugely withdraws nitrogen from the flue gas allowing capturing of low-cost and efficient carbon dioxide.

An initial example of a coal-based plant utilizing carbon capturing technology is a Swedish company Vattenfall's Schwarze Pumpe power station situated in Germany.
