Crossing over does not prevent homologous chromosomes from separating during meiosis, hence, the statement is false.
CROSSING OVER:
- Crossing over is the process whereby non-sister chromatids of homologous chromosomes exchange their genetic materials.
- Crossing over occurs specifically during the prophase I stage of meiosis I. Via this process, genetic diversity is likely to occur in the daughter cells.
- Crossing over only assures that genes of homologous chromosomes are recombined, it does not stop them from separating in the Anaphase stage.
- Therefore, crossing over does not prevent homologous chromosomes from separating during meiosis, hence, the statement is false.

Answer:
The cycle has no beginning and no end. Rocks deep within the Earth are right now becoming other types of rocks. Rocks at the surface are lying in place before they are next exposed to a process that will change them.
