Three cores were recovered from an Oligo-Miocene sequence of rocks at offshore scientific drilling sites 1, 2, and 3. Figure 7 shows the logs of the recovered cores; each log displays several different lithologic units (rock units indicated by different drawing patterns). You can consider these units as "Formations", which are the basic units of geologic mapping (Maurrasse & Collins, 2015).Your task is to correlate the three core sites in figure 7. You must use the superposition and lateral continuity principles and focus on the core's lithology. For example, we identified a unit of sandstones at the bottom of site 1 and called it Unit A. We correlated the base and the top of unit A between sites 1 and 2; now, you can identify Unit A at Site 3 and extend the correlation. Identify, name, and correlate all the lithological units present at the core sites below.

You decide that the introduction should also discuss the extremophiles that are referred to as the archaea. these single-cell organisms are considered "extremophiles" due to their ability to survive and reproduce in environmental conditions that would be hostile for most living organisms. archaea species have been isolated from highly acidic sulfur springs, ocean floor thermal vents with temperatures that exceed boiling, and subarctic ice well below freezing. while still considered to be prokaryotic, the archaea have numerous differences that place them apart from the bacteria. choose the characteristics that separate the archaea from other prokaryotic cells. select all that apply. view available hint(s) select all that apply. archaea lack true peptidoglycan in their cell walls. the morphology of the cell is rigid and is geometric in shape, similar to a sphere or cylinder. the cytoplasmic membrane lipids of archaea have branched or ringform hydrocarbon chains. all currently identified and characterized archaea have been linked as the causative agent to an animal or human disease.
