A cell shows alignment of chromosomes along the equatorial plate. What will happen next? Formation of two complete sets of chromosomes Separation of sister chromatids and centromeres Replication of DNA to form two copies of chromosomes

Separation of sister chromatids and centromeres.

Explanation:

Once chromosomes align along equatorial plate during metaphase of mitosis,  the next step of mitosis is separation of the sister chromatids and the centromeres. The separation of sister chromatids and the centromeres occurs during anaphase of mitosis. During this phase, spindle fibres which are produced from centrioles in the centrosome at two opposite poles of the cell, attach to the centromere region of the chromosomes and drag each sister chromatid of the chromosome apart towards opposite pole of the cell. This is how each opposite pole receives one chromatid from each chromosome. Later during telpophase of mitosis, cytokinesis occurs which produces two daughter cells with equal number of chromatids.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
