Using information from the primary literature (several references have been provided as a starting point below) please answer the following question: Based on your review of the literature on rewilding, what are the major scientific pros and cons for rewilding?   Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions.   Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly. Recall Nietzche’s…

Now draw a rough sketch of what the control data might look like if in addition to the specific binding, there was also a considerable amount of nonspecific binding (again using a normal dose/response curve) (do % total bound ligand vs concentration)

question1 In plants, epithelial tissue is only found as the outermost cell layer and acts as a barrier. In humans, epithelial tissue is found inside the body as well as on the surface. What function(s) does/do epithelial tissue carry out in humans? Select all that apply.   Waste storage   Filtration   Oxygen transport   Protection   Diffusion   Osmosis   Absorption
