Compost rich in cellulose is likely to be poor in nitrogen because cellulose is a structural component of plant material that is harder to break down compared to nitrogen-rich components like proteins. Microorganisms that break down cellulose need nitrogen to do so, and if there is insufficient nitrogen present, they may not be able to efficiently decompose the cellulose, leading to lower nitrogen content in the compost.

Atmospheric nitrogen is the nitrogen gas present in the Earth's atmosphere, primarily in the form of N2 molecules. Laboratory nitrogen typically refers to pure nitrogen gas produced in a lab setting. While both contain nitrogen gas, laboratory nitrogen is often purified and free of impurities, making it suitable for various scientific experiments and applications.

The process of converting nitrogen into nitrogen compounds by bacteria is called nitrogen fixation. This process is essential for making nitrogen available for plant uptake and for supporting all forms of life.

Refractory nitrogen refers to nitrogen compounds that are resistant to breakdown by microbial activity in soil, making them less available to plants. These compounds can accumulate in soil over time, impacting nitrogen cycling and plant growth. Examples include organic nitrogen compounds like lignin and humus.

Yes, nitrogen can be an asphyxiant in high concentrations. When nitrogen displaces oxygen in a closed space, it can create an oxygen-deficient environment that can lead to asphyxiation if breathed in for an extended period of time.

No, most organisms cannot use nitrogen gas directly. They rely on nitrogen-fixing bacteria to convert atmospheric nitrogen into a usable form such as ammonia or nitrate, which can then be absorbed by plants and other organisms.

Nitrogen can be fixed in ecosystems through biological processes, like by nitrogen-fixing bacteria that convert atmospheric nitrogen into a usable form for plants. It can also be fixed through human activities, such as the use of nitrogen fertilizers in agriculture.

Nitrogen was not "born" but it has existed since the formation of our solar system, about 4.6 billion years ago. It is one of the most abundant elements in the universe and plays a crucial role in various biological processes on Earth.

Nitrogen gas (N2) does not have a physical address as it is a gas that exists in the Earth's atmosphere in large quantities (about 78% of the air we breathe).

In vivo nitrogen fixing occurs inside living organisms, such as through symbiotic relationships between plants and bacteria in root nodules. In contrast, in vitro nitrogen fixing refers to nitrogen fixation that is carried out outside of living organisms, typically in a laboratory setting using isolated enzymes or bacteria.

'Nitrogen drawdown' refers to the process by which nitrogen is removed from the atmosphere or soil and stored in plants, soil organic matter, or aquatic systems. This process helps to reduce the amount of nitrogen available for activities such as plant growth or water pollution.

The nitrogen shuttle refers to the process by which nitrogen is transferred between different biomolecules and cellular compartments within an organism. This process is crucial for maintaining nitrogen balance and supporting various biological functions, such as protein synthesis and energy production. The nitrogen shuttle typically involves the conversion of nitrogen-containing compounds, such as amino acids, within the cell.

Plants mainly obtain nitrogen in the form of nitrates from the soil through their roots. This nitrogen is then used by plants to build proteins and other essential molecules. When plants die or shed leaves, nitrogen is returned to the soil through decomposition, where it can be taken up by other plants.

Nitrogen-fixing bacteria get nitrogen from the atmosphere, specifically from nitrogen gas (N2). They convert this nitrogen gas into a form that plants can use, such as ammonia or nitrate, through a process called nitrogen fixation.

Nitrogen has the chemical symbol N and atomic number 7. It is a non-metal element on the periodic table. Its most common form is diatomic nitrogen gas (N2), which makes up about 78% of Earth's atmosphere.

Yes, high concentrations of nitrogen can displace oxygen in the air, leading to oxygen deprivation and suffocation, a condition known as nitrogen asphyxiation. This is more likely in confined spaces with poor ventilation.

The person is in negative nitrogen balance, as they ingested less nitrogen (16g) than they lost (19g), meaning their body is breaking down more protein than it is building up. This can indicate a potential loss of lean body mass.

Yes, nitrogen gas consists of diatomic molecules composed of two nitrogen atoms bonded together (N2).

The balanced equation for nitrogen (N₂) reacting with hydrogen (H₂) to form ammonia (NH₃) is:

N₂ + 3H₂ -> 2NH₃

they turn the nitogen gas into the nitrates and nitrites essential for the soil

In 1 mole of nitrogen dioxide (NO2), there are 1 nitrogen atom present because each molecule of nitrogen dioxide contains one nitrogen atom.

No, nitrogen is not a solvent. Nitrogen is a colorless, odorless, and inert gas that is commonly found in the atmosphere. It is not typically used as a solvent in chemical reactions or processes.

Using ordinary air between the panes of double-pane windows can lead to condensation forming inside the window due to the presence of moisture in the air. This condensation can reduce the insulating effectiveness of the window and cause visibility issues. Nitrogen gas or very dry air is used to prevent condensation and maintain the insulating properties of the window.

Nitrogen is not commonly used as a refrigerant in typical refrigeration systems. It is usually used in applications where an inert gas is needed, such as purging and pressure testing. Refrigerants like ammonia, CFCs, HCFCs, HFCs, and hydrocarbons are more common in refrigeration systems.

They use the nitrogen in the food they eat to form their bodies, particularly proteins. They throw out excess nitrogen with the help of excretion, and their bodies are decomposed after death into various forms of nitrogen, too.
