‘’Understanding the population structure of a country and potential changes is extremely important for governments. Using examples explain this statement.’’ A population pyramid is an illustration that shows the distribution of various age groups and gender in a population-typically a country or a region. It can be drawn up for any area‚ from a whole continent or country to an individual town‚ village or city. They are also used in Ecology to determine the overall age distribution of a population;

Your last paragraph was very detailed with great information about the cell membrane‚ you stated “ The cell membrane is very thin and fragile‚ and it contains two different types of proteins. “Integral proteins are part of the membrane structure and cannot be removed without damaging or destroying the membrane. Peripheral proteins are bound to the inner or outer surface of the membrane and are easily

mosaic model of the cell membrane. What is the fluid mosaic model? The fluid mosaic model is a model conceived by S.J. Singer and Garth Nicolson in 1972 to describe the structural features of biological membranes. The membrane is described to be fluid because of its hydrophobic integral components such as lipids and membrane proteins that move laterally or sideways throughout the membrane. That means the membrane is not solid‚ but more like a ’fluid’. The membrane is depicted as mosaic because

Less guns‚ Less crime? “‘If a preschool child hits another child with a rock‚ the solution is not for every child to have a rock!”’(NICHOLS) More gun control is needed with the advances of fire arms.
