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
The answer is mitochondria.
The answer is the first choice: Blue Eyes.
Polygenic traits are those controlled by two or more genes (hence the name "poly" in the term). Other examples would be skin color and height.
Hope this helps! :)
Answer:
PpDD and PpDd
Explanation:
Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d).
The <u>possible genotypes of a pigment-eyed, dimple-chinned person</u> would be PPDD, PpDd, PPDd, PpDD while a blue-eyed person without a dimpled chin would have the genotype ppdd.
The genotype of a blue-eyed, dimpled chin child would be either of ppDd or ppDD, but in this case, the mother is ppdd and as such, the child cannot have two copies of D allele. Hence, the genotype of the child can only be ppDd.
In order for the child to have blue eyes (pp), it means that the father has to have the non-pigmented allele (p). This also means that the father is heterozygous for eye pigmentation (Pp).
<em>Hence, the genotype of the father is now limited to </em><em>PpDD</em> <em>and </em><em>PpDd</em>.
Same but like I got to answer questions before I can ask so sry
