Ferns attached to a forest rock
Ferns have small, branched leaves, not to reduce gas exchange and water loss, but to increase the surface area for spore producing structures. This demonstrates that plants develop certain characteristics for very different reasons.

2.3 Railways in Britain The railway age started with attempts to make a steam engine small enough to be fitted to a wagon for hauling coal at collieries, the wheels moving on a wooden or iron rail for guidance. Improvements to the drive mechanism led directly to the Locomotion designed by George Stephenson, and the opening of the first passenger and goods service for the 27 miles between Stockton and Darlington in County Durham. It was opened in 1825 and was quickly followed in 1830 by a line between Manchest
Living and non-living things
Living things often rely on non-living things to accomplish daily tasks. Living things have several characteristics that non-living things do not, such as the ability to move, eat, breathe, and reproduce. Living things and non-living things can interact even though they do not have the same characteristics.
