Xenotransplantation is using nonhuman animal organs in transplantation. many people are against this practice. choose the best argument about why xenotransplantion should be accepted. a. there are more people on transplantation lists than donor organs so xenotransplantion can save people’s lives. b. people on transplantation lists are not treated equally in that some are moved to the top of the list. c. there are no antigens on the surface of nonhuman animals so there would be no rejection. d. more organs can be extracted from nonhuman animals to accommodate more recipients.

Ans.  Option (A).  

Xenotransplantation can be described as transplantation of living tissues, cells or organs from one species (donor) to another (recipient). The transplanted organs or tissues are known as xenotransplants or xenografts.  

There is a worldwide shortage of grafts for clinical implantation, as people who need transplantation are more than donors, which causes many patients to die while waiting for donated organs.

Xenotransplantation can provide a continuous and unlimited supply of organs, tissues, or cells for humans, thus, it could save 1000 of patients, waiting for donors.  

Thus, the correct answer is option (A).

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
