Reproductive isolation must happen
<span>A cell can only grow so large in size because its
ability to exchange materials is affected by a growing surface-to-volume ratio.
Nature designed cells to be small in size because of the network of membranes
passing through it. If cells grow any bigger, membranes in it will not be able
to pass through its different parts and perform their purpose.
A cell is a network composed of many organelles (e.g. mitochondria, nucleus),
that communicate and work together to provide bodily functions. The cell is
small so that communication between organelles will be faster and much easier. When
cells are small they can be easily repaired when damaged and replicated when
needed.</span>
Plants would be the only option, they have no legs so they can't move. They are producers and make its own food and unable to move around its environment.
1. It can destroy the boidiversity. 2. The chemical input from the roads are washed into the water. 3. Also it can degrate the air quality. Hope this helps!!!
