Someone who has Rh-factor __________ blood cannot receive blood with a __________ type.
antigen, negative |
|
positive, antigen |
|
negative, positive |
|
positive, negative |
Blood transfer is limited by the type and Rh factor of the blood. Someone who has Rh-factor negative blood cannot receive blood with a positive type but a person with Rh-factor positive type blood can receive Rh-negative blood. Type O negative blood is the universal donor because it can be given to a person with any blood type. Type AB positive is the universal recipient meaning someone with this blood type can receive any other type of blood.
Which of the following is the formula for work?
\(W = {{F}\over{d}}\) |
|
\(W = \vec{F}\vec{d}\) |
|
\(W = {\vec{F} \over \vec{d} }\) |
|
\(W = {F}{d}\) |
Work is performed on an object when an applied force causes displacement along the same vector. Measured in joules (J) or newton-meter (Nm), work is calculated by multiplying force times displacement: \(W = \vec{F}\vec{d}\)
