Answer:
In species with polyploid, there are more chromosomal sets than in diploid one. Becouse there are more chromosomal structures available, events like mutation, recombination, DNA lose, are more probable to occur.
As the generations pass, the accumulation of these changes tend polyploid to speciation.
Meiosis I produces 2 haploid cells and meiosis II produces four haploid cells.
As food moves through the digestive tract, it spends the most time in the large intestines. This is because of the need to absorb water and partially digest fiber.
There's a great picture that I attached below that is a great representation
