In cell biology, where does DNA replication take place?
Golgi apparatus |
|
nucleus |
|
mitochondria |
|
cytoplasm |
The cell nucleus contains the genetic material of the cell and is where DNA replication takes place.
Someone who has Rh-factor __________ blood cannot receive blood with a __________ type.
antigen, negative |
|
positive, negative |
|
negative, positive |
|
positive, antigen |
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.
Convert 0C° to F°.
-32 |
|
32 |
|
16 |
|
0 |
To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(0) + 32\)
\(F° = 0 + 32 = 32\)
"The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object." This describes which of Newton's laws of motion?
second |
|
first |
|
fourth |
|
third |
Newton's second law of motion states that The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. This law basically means that the greater the mass of an object, the more force is needed to overcome its inertia.

saturated |
|
cholesterol |
|
polyunsaturated |
|
monounsaturated |
Fats come in three types, saturated (meats, shellfish, eggs, milk), monounsaturated (olives, almonds, avocados), and polyunsaturated (vegetable oils).
