The water would freeze across the surface of the lake, blocking the dissolving of oxygen and nutrients. <span>Water is actually less dense when frozen, which is why ice cubes and ice bergs all float. This is also why you can ice skate on a lake if the ice gets thick enough on the surface. Many organisms that live in freezing lakes have special adaptations which help them survive.</span>
I think it's the evaporation of water through the stomata :)
The glycolysis of glucose occurs in the cellular component
of the cytosol. The cytosol is found in the organelles in the body in which
these substance or particles are usually suspended, in which is a vital part of
where glycolysis of glucose occurs.
running water can be used as an energy source to produce hydroelectric power.
Complex organisms need cells that can perform many different functions. they need to be supported on a cellular level. Without specialized cells you they won't be able to perform different functions.
