Nitrogen is present in the environment in abundance but still we cant inhale nitrogen
What is the role of nitrogen in our body?
Nitrogen is physiologically inert. It contributes nothing to the functioning of our bodies. The cells in our body need oxygen to live, not nitrogen. we can find nitrogen in our body in form of nitrogeneous base in nucleotide.
We inhale all gases present in air fills our alveoli, by the process of diffusion, only oxygen in the air is taken into the blood stream while the other gases along with the waste CO2 is exhaled. So you do breathe in nitrogen, but it is exhaled as it is by the body.

Why are seeds an evolutionary advantage for seed plants?
Seeds allow for the transport of water and nutrients.
Seeds develop into adults without s x u a l reproduction.
Seeds protect the plant embryo and its food source.
Seeds provide the materials for photosynthesis.
The seeds an evolutionary advantage for seed plants because seeds develop into adults without sxual reproduction which means letter B.
What is the evolutionary importance of the seed?Seeds play an important role in the dispersion of plant species, that is, they ensure that plants spread throughout the environment. In addition to guaranteeing a greater area of domain for the species, competition between the newly born plant and the mother plant is also avoided.
Seeds allow the expansion of a type of plant around the world in addition to being a form of asexual reproduction that makes it unnecessary to join gametes.

what happens when a cold front replaces a warm front
Answer:
When a cold front overtakes a warm front, it creates what's called an occluded front that forces warm air above a frontal boundary of cooler air masses.
Explanation:
The presence of a cold front means that cold air is advancing and pushing underneath warmer air. This is because the cold air is ‘heavier,’ or denser, than the warm air. Cold air is thus replacing warm air at the surface.

Which of the following best explains the impact urbanization has on the carbon cycle? (4 points)
An increase in the population results in the depletion of groundwater, causing sinkholes to occur.
Decaying organic matter increases in landfills, which increases the amount of carbon dioxide in the atmosphere.
Human-made structures absorb solar radiation and cause an acceleration of the greenhouse effect.
Increased runoff causes soil to erode and prevents the growth of vegetation.
The option that best describes the impact of urbanization on carbon cycle is : ( B ) Decaying organic matter increases in landfills, which increases the amount of carbon dioxide in the atmosphere.
Effects of the organic matter on the environmentWhen organic matter decays, this leads to an increase in landfills and as the landfills increases there is also a corresponding increase in the amount in the carbon dioxide which will be released into the atmosphere.Also an increase in the population of an area does not result in the increase of carbon dioxide in the atmosphere.
Hence we can conclude that The option that best describes the impact of urbanization on carbon cycle is Decaying organic matter increases in landfills, which increases the amount of carbon dioxide in the atmosphere.
