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).
Multicellular animals have some mechanism to control cell mass that we do not understand; for in case, salamanders of different ploidies are the same size such that a haploid, a diploid, and a pentaploid organism are about the same size.
Stand in a doorway. With the arms at the side and the elbows extended press the backs of the hands against the door frame with maximal force for thirty seconds.

A forty-two year old woman decides to lose weight on a diet prescribed by an anorexic friend. She loses about thirty pounds in 45 days, but her serum potassium level falls to 2.1 mmol/L.
Discuss what determines the shape of fungal spores that are ejected into the air? Develop an hypothesis and suggest an experiment
Cyanide binds to complex IV of the electron transport system, preventing the reduction of oxygen to water. Explain the ultimate effects of cyanide on electron transport, oxygen consumption, and ATP production. How can these in turn affect a person.
