Answer:
Prophase II meiosis-chromosomes-6 and 12 DNA molecules per cell.
Explanation:
Meiosis is a unique type of division that occur in cells in which the chromosome number is decreased to half with the creation of haploid cells. It can be referred to as reduction division and it mostly occurs in organisms which go through sexual reproduction.
In prophase II , the nucleoli and nuclear membrane disappear.
The chromatids reduces in length to become short and thick .
The centromeres migrates to the polar regions and set the spindle fibres in place for the second meiotic division.
Therefore, at Prophase II of meiosis
The daughter cells are haploid. Its haploid cells should possess six chromosomes and 12 DNA molecules.
Answer: Precipitation -> evaporation -> condensation
Explanation: precipitation is when it rains, so water is delivered by the atmosphere into the ocean. Evaporation happens when water in the ocean is heated up and returned to the atmosphere. Condensation occurs when water condenses due to pressure/temp differences creating clouds.
