|
joules or newton-meters |
|
horsepower |
|
watts |
Work is performed on an object when an applied force causes displacement along the same vector. Measured in joules (J) or newton-meters (Nm), work is calculated by multiplying force times displacement: \(W = \vec{F}\vec{d}\)
Universal donor blood can be given to a person with any blood type. Which blood type is the universal donor?
O-negative |
|
AB |
|
O |
|
O-positive |
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.
Plant cells may generate energy through which of the following?
aerobic respiration |
|
all of these |
|
photosynthesis |
|
anaerobic respiration |
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.
What is a major difference between the somatic and autonomic nervous systems?
one controls thinking, the other controls feeling |
|
one is inherited, the other is learned |
|
each belongs to a different nervous system |
|
one controls voluntary activity, one controls involuntary activity |
Both are part of the peripheral nervous system. The somatic nervous system sends sensory information to the central nervous system and controls voluntary actions while the autonomic nervous system regulates involuntary activity in the heart, stomach, and intestines.
