Your Second Donation Begins the Process of Helping Save Lives! The first donation is used only after a second donation is completed. Only then can we begin to use your plasma to produce life-saving therapies to help treat a variety of diseases and conditions. FDA regulations state that the maximum frequency of donation is once in a two-day period, and no more than twice in a seven-day period. Donating plasma the second time will take much less time out of your day than your first visit to our donation center. We understand that your time is valuable and we strive to make your experience as pleasant and convenient as possible!
The definition for species evenness in my workbook is: Species evenness is a measure of the relative abundance of each species in an area. The more similar the population size of each species, the greater the species evenness.. Could someone clarify this a bit more please, as I don't fully understand the definition.
George Yancy: You have popularized the concept of speciesism, which, I believe was first used by the animal activist Richard Ryder. Briefly, define that term and how do you see it as similar to or different from racism? Peter Singer: Speciesism is an attitude of bias against a being because of the species to which it belongs. Typically, humans show speciesism when they give less weight to the interests of nonhuman animals than they give to the similar interests of human beings. Note the requirement that the interests in question be âsimilar.â
