Textbook Question
Chapter 12, Problem 3NST
If a human nucleus is 10 μm in diameter, and it must hold as much as 2 m of DNA, which is complexed into nucleosomes that during full extension are 11 nm in diameter, what percentage of the volume of the nucleus is occupied by the genetic material?
HINT: This problem asks you to make some numerical calculations in order to see just how “filled” the eukaryotic nucleus is with a diploid amount of DNA. The key to its solution is the use of the formula V = (4/3)πr3, which calculates the volume of a sphere.

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…
