The universal recipient blood type can recieve any other blood type. Which blood type is the universal recipient?
O-negative |
|
AB-positive |
|
AB |
|
O |
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.

The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (50 - 32)\)
\(C° = {5 \over 9} (18)\)
\(C° = {90 \over 9}\)
\(C° = 10\)
In taxonomy, domains are the broadest classification of life. How many domains are there?

The broadest classification of life splits all organisms into three groups called domains. The three domains of life are bacteria, archaea and eukaryota.
Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of:
1 mph to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg/s2 |
|
1 m/s2 to a mass of 1 kg |
|
1 m/s to a mass of 1 kg |
Weight is a force that describes the attraction of gravity on an object. Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of 1 m/s2 to a mass of 1 kg.
In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:
oxygen |
|
mitochondria |
|
water |
|
sugar |
Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.
