Forest fires actually help the environment, they remove plants and trees that are useless and leave space for new plants and trees to grow. After 26 years after the fire, the forest will start to grow again and will be green once again.
Have a nice day! :)
Passive transport is a movement ofbiochemicals and other atomic or molecularsubstances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy. The rate of passive transport depends on thepermeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids andproteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration and osmosis.
The answer is A. The ratio goes down as the size of the cell gets larger.
