O positive is the most common blood type and most likely to be transfused.
O negative donors are the “Universal Donor.” People with O negative blood are universal red blood cell donors. This means that their red blood cells can be transfused to any blood type.
The answer for this will be C an integration of organ systems this is because the endocrine system also works with the nervous system and immune system etc
Answer:
They used radioactive labeling techniques to build two different types of phage.
Explanation:
In 1952, a set of experiments were carried out by American biochemists Alfred D. Hershey (1908-1997) and Martha Chase. They prepared two separate virus samples, one contained DNA labeled with a radioactive isotope and the other contained protein labeled with a different radioactive isotope. They grew the two types of viruses separately, infected bacteria with the two sets of phages and analyzed the bacteria for radioactivity. From the results obtained, Hershey and Chase concluded that the viral genetic material was DNA and not protein, reinforcing the observations previously made by Avery.
Tissues form when many similar specializes cells come together.
The level of complexity in organisms from smaller to larger are:
Cells, tissue, organ, organ system, and organism finally.
Cells makes up tissue, tissue makes up organ, organs makes up organ systems, and organ systems makes up an organism.
Therefore, if the same type of cells come together, they'll make up tissue.
