That would be PH and Salinity and Temperature
Cyanobacteria don't need oxygen to survive they produce oxygen. They where the first ever known organisms on the planet and they produced oxygen in the oceans which was absorbed by iron deposits and then once the iron had oxygen the ocean got the oxygen until it got into the atmosphere and Eukaryota bacteria evolved. So the answer would be: <span>They convert nitrates from the water into nitrogen gas (N2) that is released into the atmosphere.</span>
B. because a metabolism is the breaking down of food reacting in chemical actions including homeostasis.
Sister chromatids are separated during meiosis II because homologous chromosomes separate during meiosis I.
<h3>What is Meiosis?</h3>
Meiosis is a particular type of cell division by which gametes (germinal cells are generated) through two division cycles known as Meiosis I and Meiosis II.
During Meiosis I homologous chromosomes are separated, thereby ensuring the correct segregation of sister chromatids during Meiosis II.
In conclusion, sister chromatids are separated during meiosis II because homologous chromosomes separate during meiosis I.
