Answer:
Inside a vacuum flask :
Screw-on stopper. Outer plastic or stainless steel case. Outer layer of glass coated with reflective material (or stainless steel in unbreakable flasks). .Inner layer of glass (or stainless steel in unbreakable flasks). One or more supports keep inner vacuum container in place.The vacuum flask was devised to preserve liquefied gases by preventing the transfer of heat from the surroundings to the liquid. The evacuated space between the walls (which are ordinarily glass or steel) is practically a nonconductor of heat; radiation is reduced to a minimum by silvering the glass or steel.

What are some ways that the nitrogen cycle overlaps with or influences the oxygen and carbon cycles?
Are any of these interactions between the cycles positive?
Are any negative?
What about when the nitrogen cycle is thrown off balance by the Haber-Bosch process and others like it?
How can that influence the oxygen and carbon cycles?
Are there other cycles involved that have not been mentioned in this question?
What does this discussion suggest about the nature of the Earth as one large system?
Answer:
1. Nitrification occurs when soil microbes convert ammonium into nitrate. Much of the overlap between the carbon cycle and the nitrogen cycle occurs in the soil, in processes conducted by soil microbes. Microbes break down nutrients, build new compounds for their own growth, and eventually die.
The second question im not sure sorry- the positive and negative one ;(
3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.
4. Carbon makes its way through living things as carbon-based compounds, like energy molecules, fats and proteins, eventually cycling its way back into the atmosphere. Nitrogen is mainly found in the atmosphere as well and enters the ecosystems as nutrients for plants. Water, nitrogen and carbon cycles. Carbon moves from the atmosphere and back via animals and plants. Nitrogen moves from the atmosphere and back via organisms. Water moves on, above, or below the surface of the Earth.
5. Carbon cycle, Nitrogen cycle, Nutrient cycle, Oxygen cycle, Phosphorus cycle, Sulfur cycle, Rock cycle, Water cycle.
6. Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth's plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and Antarctica.
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Earth's surface is the only habitat available to the human race. Understanding the processes by which that habitat has been created and continually altered is important to determine the causes of environmental degradation.

THIS IS DUE TOMORROW - Why is it important to reduce your ecological footprint? What services do ecosystems provide for us/future generations?
Answer:
The ecological footprint (EF) estimates the biologically productive land and sea area needed to provide the renewable resources that a population consumes and to absorb the wastes it generates—using prevailing technology and resource-management practices—rather than trying to determine how many people a given land area
Ecosystem services are the benefits that people obtain from ecosystems. Ecosystem services are indispensable to the wellbeing of all people, everywhere in the world. They include provisioning, regulating, and cultural services that directly affect people, and supporting services needed to maintain the other services.

The cause of humanity's increased water consumption is an increased population. What is the effect?
Option are not provided in the question. The complete question is as following:
The cause of humanity's increased water consumption is an increased population. What is the effect?
A. less potable water, a growing threat to biodiversity
B. more potable water, a growing threat to biodiversity
C. less potable water, a decreased threat to biodiversity
D. more potable water, a decreased threat to biodiversity
Answer:
A. less potable water, a growing threat to biodiversity
Explanation:
The increasing population of human causes increase in water consumption that leads to reduction in portable water, which is a growing threat to biodiversity .
Portable water or freshwater is used for drinking by humans beings along with that it provide habitat to many diverse marine wildlife and they are important to local ecosystems as they provide sources of income and food to humans and other wildlife.
Freshwater or portable water play very important role to control flood and erosion.
So, decrease in portable water result into decrease in biodiversity.
Hence, the correct option is A. less potable water, a growing threat to biodiversity .
