MacConkey’s Agar (MAC) plates. After 48 hours of incubation‚ it was unclear that two different bacterial colonies had grown on my TSA plate. Only one type of colony was evident. However‚ it was apparent that I had successfully isolated two different bacterial species by examining my MAC and CNA plates. Only one type of colony had grown on my MAC plate indicating a gram negative species‚ which I chose to be organism A. Similarly‚ only a single type of colony had grown on my CNA plate‚ indicating a gram

towards providing that plate techtonics theory is valid. Discuss the extent to which you agree with the statement. (40 marks) Throughout close analysing we can see patterns in the occurance of seismic and volcanic activity worlwide. These patterns can be used as clues to help discover why such events occur‚ and it is clear that both volcanic and seismic activity is most abundant on and around plate margins. However despite there being a clear link between he events and the plate boundries does this

surfaces are continually changing and other evidence was that the continents had once been joined‚ and over time had drifted apart but he couldn’t explain the mechanism behind it. 2. Evidence gathered by Ewing‚ Tharp and Hess that lead to the theory of plate tectonics was: ⦁ In the early 1950s Ewing‚ with the help of Marie Tharp‚ a cartographer‚ mapped the seafloor using available echo profiles‚ the resulting mapped showed a large canyon that traversed the length of the ridge. ⦁ Hess explains that as

Asthenosphere-lithosphere relationship is important to understanding plate tectionics. 4.
