Comparative anatomy essay A study in comparison of Crocodilia to the major four vertebrate groups of mammal, bird, amphibian and bird and how these have evolved, and the differences between the groups and whether they are due to ancestry, development or adaptation. Crocodilians and birds are closest relatives in comparison to the major vertebrate groups as they share a common ancestor that existed around 240 million years ago. Crocodilians are reptiles having scaly bodies, breathing air and…

their near-vertical bombing runs. Airframes were strengthened to accommodate the stresses of diving at nearly 400 miles per hour and pulling up with enough force to cause a pilot to black out. A swinging trapeze that lofted the bomb clear of the propeller became commonplace. Furthermore, as the state of aviation generally advanced with techniques such as metal monocoque construction, monoplane design, forced-induction engines, and the general improvement of power plants, larger bomb loads and…

Lives and millions of dollars are also the cost of fossil fuels in the Middle East. Terrorist groups such as ISIS thrive on the world's dependency for oil. ISIS stands for Islamic State in Iraq and Syria. They are an extremist military group under corrupted Shar'ah law and the Shi'ah Islamic sect. They control 2/3rd of Syria's petroleum pockets.

but also plays a very crucial role in bacterial pathogenicity(14). A flagella has mainly three parts: The basal body, Hook and filament. The basal body acts as a rotary motor while the hook is the universal joint and the filament acts as helical propeller(7). The flagella is made up of nearly 50 proteins. These form the export apparatus consisting…
