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
Answer:
The alleles for red and white coat color are co-dominant.
Explanation:
Co-dominance is the condition when none of the allele of a gene is dominant. The heterozygous genotype exhibits traits of both alleles.
In the given example, the offspring have roan coat color in which white hairs are mixed into a base coat of red. Since both the alleles are expressed in heterozygous offspring, the alleles for red and white coat colors are co-dominant over each other.
Answer:
He examined covered and uncovered meat to determine that maggots came from eggs.
Explanation:
Prior to Redi's experiment and other supporting experiments, it was formerly believed that life could emanate from non-living things, for example, the generation of maggots from rotting meat.
In 1668, a scientist called Francesco Redi disproved the idea of spontaneous generation. He did this when he experimented that the maggots from meats are only as a result of eggs laid by flies when they perched on the meat.
He placed the meat in two jars; an uncovered jar and another in a covered jar with a cloth, after several days, the uncovered jar had maggots on the meat, while the covered jar had no maggot on the meat, but on the cloth. With this experiment, he was able to demonstrate that the maggot arose from the eggs of the flies, not the meat itself which is nonliving and hence, disproved the idea of spontaneous generation.
