Mitosis does not differ from meiosis in which of the following aspects?

Identify the correct statements:
$(i)$ Synapsis occurs between homologous chromosomes during Prophase-$I$ of meiosis.
$(ii)$ Centromere division occurs during Anaphase-$II$ of meiosis.
$(iii)$ Spindle fibers completely disappear during Telophase of mitosis.
$(iv)$ The nucleus reappears at the Telophase-$I$ stage of meiosis.

Programmed cell death is scientifically termed as

What is the number of chromosomes in human cells during the following stages,respectively: Anaphase and Anaphase-$I$?

Match the following columns and select the correct option:

Column-$I$	Column-$II$
$(1)$ Attachment of spindle fibers to kinetochores	$(a)$ Prophase
$(2)$ Formation of contractile ring in cytoplasm	$(b)$ Telophase
$(3)$ Decondensation of chromosomes	$(c)$ Cytokinesis
$(4)$ Condensation of chromosomal material	$(d)$ Metaphase

The stain used for cell division is :- .........
