The Rh factor antigen in blood determines:
blood type |
|
postive or negative |
|
universal donor status |
|
universal recipient status |
Blood is categorized into four different types (A, B, AB, and O) based on the type of antigens found on the outside of the red blood cells. Additionally, each type can be negative or positive based on whether or not the cells have an antigen called the Rh factor.
In fermentation, what replaces oxygen in anaerobic respiration?
starches |
|
ascorbic acid or peptides |
|
water |
|
lactic acid or alcohol |
If no oxygen is present, cellular respiration is anaerobic and will result in fermentation where either lactic acid or alcohol is used instead of oxygen.
Which of the following is the formula for work?
\(W = {F}{d}\) |
|
\(W = {{F}\over{d}}\) |
|
\(W = {\vec{F} \over \vec{d} }\) |
|
\(W = \vec{F}\vec{d}\) |
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: \(W = \vec{F}\vec{d}\)
An air mass is a large body of air that has which of the following characteristics?
similar temperature |
|
similar moisture |
|
all of these |
|
similar density |
An air mass is a large body of air that has similar moisture (density) and temperature characteristics. A front is a transition zone between two air masses.
The energy posessed by a thrown baseball is an example of what kind of energy?
kinetic |
|
potential |
|
transitional |
|
gravitational |
Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.
