The second reason, a communications tool to convey the distribution of human activities or physical features. Absolute location, position as expressed in degrees,minutes, and seconds of latitude and longitude. Relative location, is the regional position or situation of a place relative to the position of other places. Longitude is a geographic coordinate that specifies the north-south position of a point on the Earth's surface. Latitude is measured by imaginary lines running parallel to the equator, and used ti measure distance by degrees North or South of the equator.

Some other place the population will decline because of how many people are in the post reproductive stage. If the pre-reproductive stage had a lot of kids then the population will rise due to how many people will make it to the reproductive stage, and the total fertility rate of their country.

here are some bio notes because i want to study a lot

\Diffusion - Movement of particles from an area of higher concentration to an area of lower concentration. Facilitated Diffusion - Diffusion of molecules through a protein channel. (Does not require energy) Osmosis - Diffusion of water through a selectively permeable membrane. Osmosis Pressure - Pressure that most be applied to prevent osmotic movement across a selectively permeable membrane. Active Transport - Process can move molecules from a lower concentration solution on one side of the membrane to a higher concentration solution on the other side. (Does require energy) Endocytosis - Process in which a substance gains entry into a cell without passing through the cell membrane.(Substance entering the cell) Exocytosis - Process of cellular secretion or excretion in which substances contained in vesicles are discharged from the cell by fusion of the vesicular membrane with the outer cell membrane. (Waste exiting the cell) Homeostasis - Relatively constant internal p...
