The illustration is a representation of the different ways molecules are transported across a cell membrane, that represents active transport is IV.
Active Transport is described as a process that involves the movement of molecules against a gradient or an obstruction from a location of lower concentration to a region of greater concentration.
A protein pump uses ATP, which is a form of stored energy, to move molecules during active transport.The process of active transport, which moves molecules using ATP as an external energy source.
Some examples of active transport include the absorption of glucose in the human intestine and the uptake of minerals or ions into the root hair cells of plants.
Active transportation comes in two flavors:
Primary active transport
Secondary active transport.

This statement is true. Developing countries indeed tend to have more people in urban areas than rural areas. For example, New York City has the massive population in the state of New York, compared to its rural areas upstate.
