Why is Type O blood a universal donor?

Individuals with the blood group O -/+ are called “universal donors” because their red blood cells can be transfused to people of all blood groups. It is also a fact that the Red Cross are searching for O blood donors. I know all of this even though I am only 13 years old cause I am an O blood person myself. I had this question in my head so I researched about it. I hope my answer helps you. Feel free to ask any questions.. :)

Its a logical process in which a number of premises  all believed true or sometimes found  true most of the time and combined to come up with specific conclusions. Its mostly used in applications that do involve  behavior, forecasting and makes broader generalization that is considered probable. For example a speculation that all crows are black and each time a new crow is observed  and found out that its black the assumption is increasingly confirmed. On the other hand if the crow is found not to be black then the assumption's found to be false..

Death rate can be defined as the number of deaths per 1000 in a population in a year or period.

Immigration can be defined as the number of organism entering into the population.

Emigration can be defined as the number of population going out of the population due any reason.

Despite a lot of scientific evidence and many theories why does the origin of the universe remain a question to scientists?


Though there is a lot of scientific evidence and theories to explain the origin of the universe, yet its origin remains a question to the scientist. This is because, at the origin, the universe had infinite temperature and density. These conditions cannot be reproduced in lab and tested. Also, the observable universe is smaller than the actual. So, scientists have not been able to view the whole universe. Scientists have still not completely understood about dark matter and energy which is considered to form majority of the universe. Since there are many unanswered questions, the origin of the universe also remains a question.
