Hello there!
Ripping up a peice of paper is considered physical change.
Physical change means its still the same, it just changed shape.
Chemical change cannot be changed back.
For ex) Burning paper.
Its a chemical change because it cant be undone
hope this helps!

Answer:
<h2>Meiosis I</h2>
Explanation:
1. Meiosis (meiosis I and meiosis II) produce four daughter cells from a single cell, each daughter cell contains half the number of chromosomes as compared to parental cell.
2. Meiosis have two cycles , i) meiosis I and ii) meiosis II.
3. In meiosis I, chromosomes first go replication and become double. It is the first step (meiosis I) that generates genetic diversity. During prophase I of meiosis I, homologous chromosomes pair and form synapses, a special step of meiosis.
4. There is crossing over in meiosis I which produce genetic diversity.
5. The four cells produced from a single cell become genetically different due to crossing occur which occur in meiosis I.
