Biology
1 answer:
lukranit [14]3 years ago
3 0

Answer:

No, it is a cycle, so it repeats cyclic.

Explanation:

The cell cycle is divided into two main phases: interphase and mitotic phase.

Interphase is phase characterized by the the cell growth and DNA copy (replication). During this phase, the cell prepares for division, formation of two daughter cells (mitotic phase).

Mitotic phase is subdivided into four phases:

  • prophase, - nuclear envelope breaks down, condensed chromosomes are released
  • metaphase- chromosomes are lined up, mitotic spindle is formed
  • anaphase - the sister chromatids of each chromosomed move to the opposite ends of the cell
  • telophase-final stage, nuclear envelope reforms

Pepsi [2]

Nitrogen Cycle steps:

N molecules breaking apart via nitrogen-fixing bacteria.

Animals ingest nitrogen in nitrate-containing food after plants use nitrogen-containing compounds.

The organic matter decays via decomposers

N2 is formed via denitrifying bacteria.

Explanation:

The nitrogen-fixing bacteria removes atmospheric nitrogen by fixing nitrogen through nitrification. The atmospheric nitrogen cannot be absorbed by plants and hence has to be converted into nitrates. This conversion takes place by nitrifying bacteria present in leguminous plants.

Animals (herbivores) consume the plants that have absorbed nitrogen/

When these animals die, decomposing bacteria acts on the dead organic matter, decomposition takes place through ammonification, converting the organic nitrates into ammonia

The nitrates are converted back again to nitrogen by the action of denitrifying bacteria.  

The nitrogen thus formed is released to the atmosphere
