Explanation:
Picture A which shows an overall negative charge represents an anion. Anion are formed when an atom gains an electron. In doing that, the total number of electrons (negative charge) is greater than the number of protons (positive charge), hence it would have an overall negative charge.
Picture B which shows a neutral charge represents a neutral atom. In an atom, the number of electrons equals the number of protons.
Picture C which shows an overall positive charge represents a cation. Cation are formed when an atom loses an electron. In doing that, the total number of electrons (negative charge) is less than the number of protons (positive charge), hence it would have an overall positive charge.
The statement about
“Upwelling is a process in which warm, nutrient rich water from the deep ocean
rises to the surface” is false. It must be the cold, nutrient rich water from
the deep ocean that must rise to the surface and replaces warm surface water.
The cause of upwelling is when the local wind patterns blow along the northwest
coast of South America causing local surface currents to move away. The warm
water is then replaced by the deep cold water
