The answer is B) Perissodactyls
True. isotopes of uranium i.e U 235 is used as nuclear fuel in power plants
The greater the surface area of a cell, the faster the cell can transport materials across its membrane because there is more area to absorb/excrete materials. We also want the surface area much higher than the volume of a cell. the more volume a cell has the slower the transport of diffusion will be. If the cell is smaller because it has a higher surface area than it does volume. Because of this larger SA:V ratio, smaller cells will transport materials faster.
Because there will eventual reach a point where the food or some other necessity runs out and instead of growth continuing, it stays at relatively constant.
Converting solar energy does not affect the earth system
