What are the phases in meiosis and explain
densk [106]

Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.

prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)

metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.

anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.

telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.

interphase This is a resting period.

SSSSS [86.1K]

The correct flowchart is energy - > atmosphere - > air pressure - > convection - > global winds. This is a very simple process as explained.

<h3><u>Explanation:</u></h3>

The energy from the sun actually heats up the land surface and the water surface of the earth. As the land gets heated up, the layer of atmosphere that is adjacent to the land and water also gets heated up. This leads to the decrease of air density as the heat causes expansion of gases. With decrease in air density, the air pressure also drops and the air from the cooler layer of atmosphere above comes to fill up the space and this heated air goes up. This causes the convection current to get set up. This causes the global winds and different oceanic currents to flow all over the earth throughout the year.
