Give three instantaneous scale (time) examples of Earth's systems, two long-term scale (time) examples of Earth's systems, and three examples of cycles of Earth's systems. Why are volcanoes and volcanic activity a good example of system interactions?

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

a electronegativity decreases beacuse the size of nucleus is bigger.
