In the cells of some organisms, mitosis occurs without cytokinesis. this results in a. cell cycles lacking an s phase b. cells lacking nuclei c. cells that are unusually small d. cells with more than one nucleus

In the cells of some organisms, mitosis occurs without cytokinesis. this results in THE CELLs WITH MORE THAN ONE NUCLEUS. After the DNA duplication in the cell, mitosis occurs during which two chromosome sets are separated by the formation of two nuclei. Lack of mitosis would lead to lack of cytokinesis ie., cytoplasm and nuclei will not e divided and would be present in a single cell itself.

The answer is ozone layer.
