    I think you have understood????????????

    REAGAN RICHKID   Posted on 1 month ago

    People with type O- blood are called universal donors because their donated red blood cells have no A, B or Rh antigens and can therefore be safely given to people of any blood group. ... Plasma transfusions are matched to avoid A and B antibodies in the transfused plasma that will attack the recipient's red blood cells.

    there are two types of movement namely;-
    =>locomotion
    =>movement of curveture

    REAGAN RICHKID   Posted on 1 month ago

    In the world of mechanics, there are four basic types of motion. These four are rotary, oscillating, linear and reciprocating. Each one moves in a slightly different way and each type of achieved using different mechanical means that help us understand linear motion and motion control
