Which organisms transform nitrogen to a form that is useful to plants?          

Answer : Bacteria transform nitrogen to a form that is useful to plants.              

Bacteria helps in a process called ammonification where ammonia is oxidized to nitrites and then to nitrates and these nitrates are the most usable form for plants.    

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
