A. the distribution of sand on an ocean floor
Homologous chromosome pairs are separated
Meiosis 1 refers to the initial stage of meiosis where one parent cell divides into two daughter cells. This stage is where homologous pairs of chromosomes will segregate and separate from each other and move into the two daughter cells which result in the division of the total chromosomal number by half.
<h3>What happens during Meiosis 1 ?</h3>
Meiosis I ends when the chromosomes of each homologous pair arrive at opposing poles of the cell.
- The microtubules disintegrate, and a new nuclear membrane forms around each haploid set of chromosomes.
- The chromosomes uncoil, forming chromatin again, and cytokinesis occurs, forming two non-identical daughter cells.

Answer:
Nanotechnology has bring up major advances in our everyday life. For example, the use of Nanobots that are extensively used now a days in medicine to make surgeries faster and accurate. By the use of nanotechnology, major problems like cancer can be treated by using cell by cell therapy. It is also utilized in curing genetic defects. Major drug designing and drug delivery has been made easier using nanotechnology.
Nanotechnology doesn't have any visible disadvantages but there always remains a fear like introduction of some extra contaminants and toxins in the environment. But mostly i agree with use of nanotechnology for the betterment. Furthermore we don't have any more advance techniques to fight problems than this technology.
