The correct order of sequence is B-A-C.
Anaphase begins with separation of the duplicated centromeres of each pair of sister chromatids. The daughter chromosomes starts moving toward opposite poles due to the action of the spindle fibres. As this stage chromosomes appear like V or J shape. At the end of anaphase, a complete set of chromosomes has gathered at each pole of the cell.
Identical twins don't have the exact same chromatic make-up, the chances of a meteor hitting the earth within the next 60 seconds are higher than someone having the same chromatic make-up, hope this helps
Answer:
The outcome resulting from crossing over is increase in the variability of phenotypes.
Explanation:
The non-sister chromatids tend to exchange some of the segments of chromosomes during the process of meiosis. This phenomenon is termed as crossing over or recombination.
Due to crossing over, a variety of different combinations are achieved in the genes. Hence, crossing over results in increased number of variability of phenotypes. The wide variety of genetic diversity produced is due to this phenomenon i.e crossing over or recombination.

The algae increase the autotrophy by offering photosynthesis to the fungi in the lichen organism.
A lichen is an organism consisting of a symbiotic association between a fungus (the mycobiont) and algae. The mushroom brings water and mineral salts. The alga produces, by photosynthesis, various organic compounds of which it gives a part to the mushroom.
