A species specific use of the biotic and abiotic factors in an environment is collectively called the species' habitat. It is because the abiotic and biotic factors plays an important role in the habitat of the species where it helps it in certain ways.

1. Homologous chromosomes are separated- Anaphase I

2. Homologous chromosome are paired- Prophase I

3. Nuclear envelopes form around separated chromosomes- Telophase I

4. The centrosome replicates- S phase

Explanation:

1. Anaphase I- the phase marked with the separation of the homologous chromosomes present in the diploid organisms

2. Prophase I - During pachytene of prophase I, the homologous chromosomes are paired at a synaptonemal complex

3. Telophase I- The separation of homologous chromosomes are surrounded by a temporary nuclear envelope

4. S phase- the phase during which the centrosome replicates which forms the mitotic spindle.
