Answer 1

Question #58381, Biology Human Anatomy and Physiology

The first negative blood (O-) for a long time was considered universal. Hence, theoretically, it can be transfused to any person. In this case, the answer is b. B+ and O-

Although theoretically it can be transfused to any person, sometimes it turns out to be incompatible with other blood groups. As the price of such errors may be too high, now the blood group that does not match the blood type of the recipient is transfused only when there is no alternative. In this case, the answer is e. none of the above can be transfused safely
