Ways in which living organisms differ from each other There are many ways in which living organisms differ from each other. In this essay I will discuss the various ways of which this occurs. There are two different types of cells‚ there are prokaryotes and eukaryotes. Within eukaryotes there are different structures and similar structures. For example; in a plant cell they have a nucleus‚ mitochondria an ER‚ and a Golgi body. These are the same as animal cells; however they differ because plants

RETAINING WALLS AND REINFORCED SOIL SLOPES Retaining walls and reinforced soil slopes are used in areas where free-standing (natural) earth slopes are undesirable‚ usually because of space restrictions. These walls have‚ in the past‚ normally been poured reinforced concrete (gravity or cantilever)‚ timber‚ steel‚ or precast concrete cribbing‚ stone-filled wire-basket gabions‚ timber or steel sheeting‚ or steel soldier pile and lagging walls‚ all of which provide external support to the

ozone layer or ozonosphere‚ region of the stratosphere containing relatively high concentrations of ozone‚ located at altitudes of 12-30 mi (19-48 km) above the earth’s surface. Ozone in the ozone layer is formed by the action of solar ultraviolet light on oxygen. The ozone layer prevents most ultraviolet (UV) and other high-energy radiation from penetrating to the earth’s surface but does allow through sufficient ultraviolet rays to support the activation of vitamin D in humans.
