Nitrogen is present in the environment in abundance but still we cant inhale nitrogen
<h3>
What is the role of nitrogen in our body?</h3>
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.

Answer:
Iodine has more protons
Explanation:
Iodine has an atomic number of 53 whereas sulfur has an atomic number of 16. The atomic number is equivalent to the number of protons, hence iodine has the greater amount.
Answer:
True
Explanation:
Although the amount varies, the overall amount of carbon on earth is stable.
The answer to finish this sentence would be ''Scientific law'' because statements that describe what scientists usually expect to occur each time in situations is this since scientists test things in order to gather data and certify it to make it a scientific law.
<u>Answer:</u> The weight of the person above the surface of a planet is 635.83N.
<u>Explanation:</u>
To calculate the weight of a person, we use the formula:
....(1)
where,
w = weight of an object
m = mass of the person = 65kg
g = acceleration due to the gravity of the planet
For the calculation of weight, we need to first find the acceleration due to gravity and for that we use the formula:
where, g = acceleration due to gravity = 
G = Universal gravitational constant = 
M = mass of the planet = 
r = distance of the person from the planet = 
Putting values in above equation, we get:
Putting this value in equation 1, we get:
Hence, the weight of the person above the surface of a planet is 635.83N.
