Which process must occur before any cell division can take place?
Fertilization
What k must happen before meiosis can begin?
A duplication of the chromosomes is what must happen before meiosis can begin.
Why must the life cycle of sexually reproducing species alternate between haploid and diploid stages?
Meiosis maintains the normal diploid number by halving the number to make the gametes and then allowing the diploid number to be restored through fertilization. For example in humans: Germ cells undergo meiosis --> Sex reproduction 2n germ cells --> 1n gametes --> 2n fertilization
What must happen before meiosis or mitosis can take place?
Before Meiosis 2, the cell must first go through Meiosis 1. This is when the cell splits into two cells, each with two chromosomes.
In order for the sperm cell to achieve a diploid state what must occur?
Fertilization
What process must occur first before any cell division take place?

When a cell undergoes meiosis one cell becomes four what also occur from meiosis?
B. Cells must divide twice before meiosis is complete C. Cells produced after meiosis I are diploid. D. Cells produced after meiosis II are haploid.
What events must be completed before implantation is successful?
before implantation,fertilization must occur followed by 3 -4 divisions of the zygote.implantation occurs at 16 celled stage.
