6. Nitrogen Cycle - How can atmospheric Nitrogen become available for use by organisms?
Explanation:
Nitrates and ammonia resulting from nitrogen fixation are assimilated into the specific tissue compounds of algae and higher plants. Animals then ingest these algae and plants, converting them into their own body compounds. ... The action of these bacteria tends to deplete soil nitrates, forming free atmospheric nitrogen.
The atmospheric Nitrogen should become available for using the organism should be explained below.
Availability of atmospheric Nitrogen:Here the nitrated and ammonia that should be lead from the fixation of the nitrogen that should be assimilated into the specific tissue compound with regard to algae and higher plants.

Write a paragraph about air, land and water pollution.
Answer:
AIR POLLUTION:
This tern is not something new, it has been existing since he time of industrial revolution where in big chimneys are pointed out in the air which releases harmful gases into the atmosphere. This phenomenon has been increasing since then as the industries have been developing simultaneously. Today, air pollutants have shown a great effect on plantations, health and life, decreasing the enjoyment of living, rising medical costs, causes global warming and also causes the destruction of the ozone layer.
One of the major causes of air pollution is the release of carbon di oxide into the atmosphere. This happens because of deforestation and fossil fuel burning. Sulfur dioxide is another main air polluter and is released into the atmosphere by the burning of sulfur containing compounds of fossil fuels. Sulfur dioxide is very harmful for the humans on high concentration and sulfur in the atmosphere is the main cause of acid rains. Chlorofluorocarbons also contribute to air pollution by reducing the ozone layer in the stratosphere. CFC’s are produced by the burning of plastic foam items, leaking refrigerator equipment and spray cans.
WATER POLLUTION:
Contamination of available natural water by industrial wastes and other waste products can be defined as water pollution. Factors causing water pollution can be categorized into two different groups; Point sources and Non- point sources.
Point sources are easy to identify and control. Some point sources of water pollution include waste products from factories, waste from sewage, waste from power plants , waste from underground coal mines and waste from oil wells. They are called point sources because these are the direct sources of water pollution and be reduced and monitoredNon- point sources are ambiguously defined and are much harder to control. The term non -point source encompasses a large range of sources like when rain and snow moves through the ground and picks up major pollutants and mover towards a major body of water, the runoff of fertilizers from farms animals and crop lands, air pollutants getting washed or deposited to earth, and storm water drained from streets parking lots and lawns.
LAND POLLUTION:
The contamination of and with different kinds of wastes is called land pollution. The major causes of land pollution are construction, domestic waste , industrial waste and agriculture.
The rising construction of building takes away the trees that takes away the homes of the animals living there. As there are more and more people inhabiting on our planet, the demand for food increases and the forests are cut down to make farm lands. In addition, Herbicides, pesticides, artificial fertilizers and animal manure are washed into the soil and pollute it. Tons of domestic waste is dumped everyday from homes offices etc. They can be recycled or burnt in incinerators. There are still more waste machinery products such as refrigerators and washing machines that are dumped in landfills simply because they cannot be recycled. Plastic factories, oil refineries, nuclear waste disposals, and large animal farms, all lead to land pollution.
WAYS TO STOP POLLUTION:
We can help to reduce global air pollution and climate change by few ways:
Driving a car that gets at least 35 mpg, walking, biking, and using public transportation, using CFL bulbs over incandescent bulbs, buying only energy efficient appliances, recycling newspaper, aluminum, and others, planting trees, avoid purchasing products that contains CFC’s, supporting much stricter clean air laws and enforcement of international treaties to reduce ozone depletion and slow global warming

The difference in the climate is because of the latitude.
Explanation:
The climate of a particular region differs from that of another region because of many reasons. One of the reasons is the difference in the latitude of the regions. The difference is in the amount of solar radiation received by the different regions. In the polar region, the temperature is low and it is cold there. While, in the tropical regions, the temperature is high and therefore it is warm in these regions.

Answer:
Biodiversity is defined as the variety of life forms existing on the planet and the number of species living within an area. The notion also covers the way diversity changes over time and moves from one location to another (“Facts on biodiversity,” n.d.). There is terrestrial and marine biodiversity that includes species living on Earth and in the sea. A number of species dwelling in a particular area helps to monitor the aspects of biodiversity. Maintaining biodiversity is important for people’s well-being since it plays a significant role in the contribution to human health and provision of raw materials. However, currently people often face the loss of biodiversity. Today this process is happening at a much faster pace than it did 50 years ago (“Facts on biodiversity,” n.d.). As a matter of fact, around 90 percent of all the fish on the planet was exploited within the last 50 years, a quarter of bird kinds were killed, and 70 percent of forests was destroyed. In addition, extinction threatens 18 percent of all mammals, 5 percent of the fish, and 8 percent of plants. Thus, it is possible to assume that the loss of biodiversity on Earth, which takes place nowadays, is directly linked to anthropological factors, including overhunting, overfishing, consumerism, and agricultural practices.

Answer:
4. food, shelter and water
5. Sabre-toothed Cat and Woolly Mammoth
6. food and water resources
7. World Ocean
9. 3 specie
Explanation:
All living things depend on their environment that supply food, shelter and water that is necessary for their survival. Sabre-toothed Cat and Woolly Mammoth are the two species that have gone extinct due to unfavourable environmental condition. The best way to wipe out a species is to remove food and water resources. The largest ecosystem in the world is World Ocean where two third of all species live. Of the 30,000,000 species on Earth, three species are lost each hour. In conclusion, Bill Nye states that "As more and more species disappear, it's harder and harder to keep an ecosystem in balance because every specie in the ecosystem balances other specie.
1. The ecosystem is defined as the relation of plants and animals, which depend on each other and work efficiently with the surrounding. For an ecosystem to be healthy, the diversity of the organisms are necessary and proper availability of resources.
2. The four types of the ecosystem are terrestrial, artificial, lentic, and lotic. Terrestrial refers to the ecosystem on land, artificial ecosystems can be human-made, lentic and lotic are the types of aquatic ecosystems.
3. In the video, Bill Nye was trying to demonstrate that everything depends on its building block and resources.
4. The biotic components of the ecosystem depend on food, shelter, and water.
5. Extinction refers to the complete elimination of an organism due to natural or human-made factors. Examples of extinct animals are the Wolly mammoth and Dinosaurs.
6. The best way to wipe out species is the change of ecosystem or the habitat in which the organism is thriving.
7. The largest ecosystem in the world is the ocean, where the majority of the species are found and some of them are yet to explore.
8. The biodiversity can be increased by increasing vegetation, diversifying the resources, making shelters available, and plenty of water.
9. Each hour approximately 3 species are lost. It can be due to natural calamity or human factors.
10. The preservation of the ecosystem is necessary, and the soon endangering of the species will lead to unbalance of the ecosystem, as species depend on each other.

How did totalitarian regimes in the Soviet Union, Italy, Germany, and Japan come to
power after WW1?
I
Explanation:
A totalitarian ruler leads a government that maintains complete control over every
part of public and private life of the citizens in that country. The economic problems
that resulted from World War I and the Depression led people to question
whether democratic government could improve their lives. Totalitarian
governments appeared to provide a sense of security and offered a
strong direction for the future.
Both Communism and Fascism used aspects of totalitarianism
as part of their governments. In general, both used dictators, only
allowed one political party, and denied many individual rights.
Police terror was used for control and to get rid of any opposition.
Controlling media sources (newspapers, television, radio etc.)
with propaganda and limiting what was reported helped influence
what people thought. However, Fascism believed in an extreme form
of nationalism and pride in the country, while Communism focused on
the spread of their beliefs worldwide. Communism did not allow private
property and eliminated social classes. Fascism believed that each class
had a role to play in society and supported private property. During the 1920s
and 1930s, four major totalitarian governments developed – one was Communist,
The Soviet Union under Joseph Stalin
After Vladimir Lenin’s death, Joseph Stalin took power. He wanted to strengthen his power and the Communist state. He used
his secret police to stop any riots and arrest or kill anyone who spoke out against him. In 1933, he began the Great Purge to

eliminate his political rivals in the Communist Party and the government. He knew that in order to
compete with other modern countries, the U.S.S.R. (Soviet Union) needed to fix its economy. He
began a series of Five Year Plans to improve the Soviet Union’s industries. Production of steel,
coal, and oil increased dramatically, but Stalin set impossibly high production rates. Stalin took
control of all privately owned farms and began a program of collectivization. Hundreds of families
worked the collective farms to produce food for the country. Many landowners and peasants
resisted by destroying fields and killing their cattle and sheep. Millions died as a result of famine
from the damages and also attacks by the secret police to stop the rebellions. By the mid-1930s
Stalin changed the Soviet Union into a totalitarian state and made it into an industrial power.
Italy under Benito Mussolini
In the early 1920s, Italy was struggling economically and politically. Benito Mussolini’s Fascist
Party fought with the Communists for political power and won. Mussolini promised to restore the
power and glory of the Roman Empire. One way to do this was to expand Italy’s empire. In 1935, Mussolini invaded Ethiopia in
East Africa. Italy continued to expand by invading Albania in 1939. These invasions elevated Mussolini’s popularity and control.
Japan under Emperor Hirohito and Hideki Tojo
When the Great Depression hit Japan, many Japanese blamed the government for the economic problems. Military leaders
gained public support and won control of the government. Because the military kept Emperor Hirohito as the symbolic leader,

the diagram illustrates the three stages of cellular respiration. In which stage is carbon dioxide released?
Answer:
Kreb's cycle
Explanation:
As depicted in the image of this question, aerobic cellular respiration is made up of three stages namely; glycolysis, Krebs cycle and electron transport chain (ETC). Glycolysis is the first to occur in the cytoplasm of the cell, after which it is followed by Krebs cycle, which uses the products of glycolysis as a starting material.
At the end of Krebs cycle, 2 molecules of carbon dioxide (CO2) are released as waste products. This release of CO2 occurs specifically at stage 3 and 4 of the citric acid cycle or Krebs cycle.
