Darwins <em>theory</em> of <em>evolution</em> explains how modern organisms evolved over long periods of time through descent from common ancestors. <em>Darwin</em> meant that different, yet ecologically similar, animal species inhabited separate, but ecologically similar, habitats around the globe.
oxygen can only hold two bonds with other elements.
The term applied when water passes through a selectively permeable membrane from an area of high to low concentration is called osmosis. Osmotic pressure is defined as the amount of external pressure that is required to stop the net movement of the solution across the semi permeable membrane. In terms of biology, osmosis has great importance as most of the membranes in our body are semi permeable. Permeability depends on several factors such as charge, solubility, solute size and chemistry. Osmosis is the process that provides the primary means through which water travels in and out of the cells.
