Answer:
The correct phases would be
Homologous chromosomes are separated: It occurs during anaphase I of the meiosis I. It is the third phase of meiosis I during which homologous chromosomes are separated and pulled in opposite direction with the help of spindle fibers.
Homologous chromosomes are paired: It occurs during prophase I. The pairing of homologous chromosomes is termed as synapsis. The pairing is initiated in the zygotene stage of prophase I of the meiosis I.
Nuclear envelopes form around separated chromosomes: It occurs during the telophase I. It is almost opposite to the prophase I. After this phase, cytokinesis takes place.
The centrosome replicates: The replication of centrosome takes place during the S phase of the cell cycle. They migrate to the opposite ends during the prophase.

Arteries carry away the blood from the heart, these are the oxygen riched blood and of course the Aorta for that matter since the largest artery is the AORTA. Veins are the vessels that carry blood to the heart (Superior and Inferior Vena Cava)</span>
Helper T cells are very important cells in the humans immune system. They help activate B cells to secrete antibodies and macrophages to destroy ingested microbes and cytotoxic T cells to kill infected target cells.
