Answer:
Low - The generation of nitrates (NO 3-) requires oxygen, so the oxygen levels will be low
Explanation:
Nitrates are formed when the ammonia react with oxygen present in water. The oxygen which react with ammonia is not the oxygen of water molecule, it is the dissolved oxygen. This oxygen is used by aquatic animals for breathing. If nitrates are formed so the concentration of dissolved oxygen will be lowered which causes suffocation and bad impact on marine organisms and the whole ecosystem will be disturbed.
Answer: lithosphere (land), hydrosphere (water), biosphere (living things), and atmosphere (air).

The plants that were allowed to self pollinate were the F1 plants.
The plants that are true breeding are P generation plants.
The plants where there were 3times as many tall plants as short plants are in F2 generation.
<h3><u>Explanation:</u></h3>
This question is based on the Mendel’s Experiment. Sir Gregor Johann Mendel was the father of genetics who experimented on garden pea plants <em>Pisum</em> <em>sativum</em> to see whether the characters got mixed or not and to know the real cause behind different traits of same character in plants.
He took the pure homozygous tall and short plants separately which he called as parental generation or P generation. These plants were homozygous, hence pure breeding.
As these plants were crossed between themselves, then the F1 generation showed all tall plants. This is because of the heterozygous plants which showed character of dominant trait. These plants were allowed to self pollinate.
As a result of self pollination of the F1 plants, the F2 plants were 75% tall in number whereas the other 25% short, which gave the phenotypic ratio of 3:1.
In the course of recent years, 60 percent of all biological community administrations have declined as an immediate consequence of the change of area to the creation of nourishments, powers and strands. This ought to shock no one, say seven of the world's driving ecological researchers, who met to all things considered study the pitfalls of using markets to prompt individuals to assess the natural expenses of their conduct and arrangements. We are getting what we pay for.
