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.
The awnser is the last one
The answer for this question is C.
Eutrophication results in the death of trout and other fish as a result of asphyxiation from the lack of oxygen. Eutrophication involves the enrichment of water by nutrients salts such as phosphates, nitrates among others, that causes structural changes of the aquatic ecosystem such as; increased production of algae and aquatic plants, depletion of fish species, deterioration of water quality and other effects that impact negatively the aquatic ecosystem.

Explanation:
The water cycle is the path that all water follows as it moves around our planet.
