1. You are studying 2 wetlands in eastern Ohio - one that has become highly invaded by purple loosestrife (Lythrum salicaria). These wetlands typically contain over 100 species, but in an amazing coincidence, both your sites only have 6 total species:Species Site 1 # of Individuals site 2 of IndividualsCarex / Site 1 # of Individuals= 167 + Site 2 # of Individuals 76Conocarpus/ Site 1 # of Individuals=52 +Site 2 # of Individuals=0Daucus carota/Site 1 # of Individuals= 94 +Site 2 # of Individuals=32Lythrum salicaria/Site 1 # of Individuals= 0 +Site 2 # of Individuals= 347Poylgonum / Site 1 # of Individuals= 63+ Site 2 # of Individuals= 29Rumex crispus/ Site 1 # of Individuals= 23 +Site 2 # of Individuals= 4Typha latifolia / Site 1 # of Individuals= 309 +Site 2 # of Individuals= 85 A. Calculate the Shannon-Weiner Diversity Index for this community. Has purple loosestrife influenced diversity?2. You are studying bird immigration to 2 small islands off the coast of San Diego, California; the islands are identical in size and habitats, but one is substantially further from the mainland. The maximum immigration rate is eight new bird species to one island each a year, and a maximumextinction rate of 2. The other island has a maximum immigration rate of only 3. Based on the above information, you can make an appropriate assumption about extinction rate on the second island. There are 492 resident bird species in San Diego.A. Assuming equilibrium on these islands, draw an appropriately labeled figure (with correct values) that includes the predicted patterns for the near and far island.B. How many species do you predict to be on each island? (Note: I'm only looking for an estimation here, a specific pattern of diversity.)C. Imagine 2 different islands - one close to the mainland and small, the other far from the mainland and large. Which island has more species? Defend your answer with 1 or more appropriately labeled figure(s).

The idea is that this arrangement will allow animals and plants to migrate between refuges. Why would such migration be significant. Examine the F1 offspring from this cross.
If all other variables remain constant, when 2-action potentials enter synaptic terminal and produce pair of EPSPs in the muscle fiber, larger EPSP is produce by the secretion of:
The mitochondria in them have a protein called thermogenin, which allows the flow of hydrogen ions through an inner mitochondrial membrane (bypassing the ATP synthase). Based on this and your understanding of cellular respiration, propose a mechanism..
