1.) Were the North American megafauna wiped out by early human colonizers? The Overkill hypothesis is of the Clovis crossing into a “virgin continent” (The America’s) and wiped out the megafauna due to overhunting. First developed by Paul Martin in the 1960’s‚ Clovis started to occupy North and South America 13‚500-12‚500 years ago; soon after early sites were established 17 genera of North and South American megafauna went extinct between 13‚250-12‚900 (other species such as ground sloths become

absence of one in the prokaryotes; Eukaryotes also have distinct membrane-bound organelles‚ while prokaryotes do not (Stanier et al.‚ 1970a; Mauseth‚ 2009). It is after discovery and examination of these organelles that first led to the Endosymbiont Hypothesis or Endosymbiont Theory‚ as it is sometimes called (both terms are used throughout). In this essay we shall look at the history of the theory‚ how it was formed‚ who the most influential collaborators were‚ and how it is applied to the evolution

backed with the data collected. The initial heart rate before the drug‚ hemp was applied‚ was 216 BPM. The final heart rate‚ with the drug was 132 BPM. That is a change by -84 BPM. This proves that hemp lowered the heart rate of the Daphnia‚ like the hypothesis stated. The overall average for all the groups‚ there is a similar trend with a -7% change meaning the every test had the same outcome of the heart rate decreasing. There

five steps of hypothesis testing and the 5% significance level (i.e. alpha = .05)‚ does showing the film change students’ attitudes towards the chronically mentally ill? What does it mean to set alpha at .05? Alpha means making a Type I error same as significance level. When the alpha is at .05 it means that the researcher doesn’t want to take a big risk therefore sets the alpha to .05. By doing this it will make it hard for hypothesis testing process to reject the null hypothesis unless it is
