This happens during meiosis I, in the Anaphase I stage. Meiosis is a type of cell division in sexually reproducing organisms consisting of two rounds of cell division ( meiosis I and meiosis II) but only one round of DNA replication, result in cells with half the number of chromosomes sets as the original cell. In meiosis I homologs pair and segregate away from each other, the cell division in meiosis that separates homologous chromosomes, and after that the cells are haploid.
The answer to this question is rather simple, it's true. You are to use the Heimlich maneuver, or abdominal thrust when someone is choking. This is the most efficient way to recover someone from this state of choking.<span />
A they belong to the same group on the periodic table
In seedless plants, a fertilized egg will develop into a sporophyte. The sporophyte releases haploid spores. Seedless plants include ferns, club mosses and horsetails. They are seedless because they do not produce seeds and are instead dispersed like bryophytes.
By trapping harmful substances I believe :)
