Explanation:
Duplication of chromosomes, Homologous chromosomes separated, Crossing over, sister chromatids separated
A they are non-cellular they can’t make their own energy and only living host cells have the ability to mutate
Only eukaryotic organisms, or those whose cells contain nuclei, undergo mitosis.Our body cells are somatic cells(skin,cheek,stomach cells). These cells must go through mitosis to maintain daily functions of the cells like growth and repairing damaged tissue.
Total→$120×80=$9600__suppose all 80 is girls
extra→$9600-$9210=$390
difference→$120-$105=$15
opposite→$390÷$15=26boys
girls→80-26=54
