The rate of diffusion of ions through the membrane of a nerve cell is proportional to the surface area of the membrane. Nerve cells are basically cylindrical in shape. If the rate of diffusion through the membrane of a cell with diameter dis R, the rate through the membrane of a cell of the same length but with diameter 2d will be

Answerthe global climate during the paleogene departed from the hot and humid conditions of the late mesozoic era and began a cooling and drying trend which dispite having been periodically disrupted by warm periods such as the paleocene-eocene thermal maximum, persists today;

An adiabatic process is one which occurs without the transfer or matter or heat in a system.
