What is special about nitrogen, and what is its main function in the atmosphere
inna [77]
Nitrogen is the most abundant of the gases present in the atmosphere. 78 percent of the atmospheric air comprises of nitrogen, oxygen makes up for 21 percent and all other gases make up for the remaining one percent. Oxygen is a highly flammable gas and in the absence of nitrogen it would not have been possible to utilize this atmospheric oxygen, hence the presence of nitrogen reduces its flammability and also neutralizes the toxicity of other gases. Another way to explain this question is - The vital thing about Nitrogen is that it gives air to people to take in, 78% of the air we take in is Nitrogen and just 21% is oxygen, 1% is different gasses. On the off chance that the air was unadulterated oxygen then everything would be to a great degree flamable, and it would likewise be hurtful to people. Nitrogen assumes a vital part in our lives. Oxygen can be poisonious on the off chance that it was the main gas noticeable all around... Nitrogen is too much critical, else we would all die.... Also, I seek oxygen stays 21% after it can be hazardous. Definitely, you ought to realize that Nitrogen can likewise be risky in A few ways, you can look that up and take in more about it, however at this moment we're looking at something else and I would prefer not to be insignificant by any stretch of the imagination, so I'll simply adhere to the Inquiry on the point as apose to the Entire whole theme. I know I have addressed your inquiry, and I believe this was useful.

Hope this helps

Which of the following are part of the body’s first line of defense against pathogens?
Fed [463]

The answer is "D"

The body's first line of defense is also known as Innate immunity and incudes mucous membranes. Both the intact skin and mucous membranes of the body offer a high degree of protection against pathogens.

 A good example is the mucous membrane of the respiratory tract. It is lined up with cilia and covered with mucus. The coordinated beating of the cilia drives the mucus up to the nose and mouth where the trapped bacteria can be expelled.

(Lymph nodes and white blood cells belong to the second line of defense, not the first)
