Relating back to your graphs from the previous question answer the following: a) name and briefly describe the biological processes that are operating in the lake to produce the observed data.  Explain how these processes would account for your prediction of the results for a heavily overcast day. b) Describe how the introduction of extremely high levels of nutrients such as nitrates and phosphates (basically algae fertilizer) would affect subsequent oxygen level observations over the next several months. Consider the fact that the algae will eventually die and get decomposed by bacteria and fungi.

Identify and explain the process in eukaryotic cells that will proceed normally whether oxygen (O2) is present or absent. How is this possible? Why is this such a necessary and positive adapation within cells?

Compare and contrast (IN DETAIL) synaptic signaling with hormone signaling. Consider all factors in how they work, the pathways they use, effects they have, etc. when deciding on similarities/differences.

Choosing one or more of the processes we learned about in this unit, create an analogy or multiple analogies from real life scenarios that can be used to compare to the cell process you chose. Explain how they are analogous.
