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 |
|
1 mph to a mass of 1 kg |
|
1 m/s to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg/s2 |
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 the pancreas, lipase converts fat to:
amino acids |
|
complex carbohydrates |
|
glycerol and fatty acids |
|
simple sugars |
The acids produced by the pancreas contain several enzymes that aid in digestion. Lipase converts fat to glycerol and fatty acids. Pancreatic amylase breaks down complex carbohydrates into simple sugars. Trypsin converts polypeptides (the building blocks of protein) into amino acids.
The energy posessed by a thrown baseball is an example of what kind of energy?
transitional |
|
gravitational |
|
kinetic |
|
potential |
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.
Which part of the respiratory system helps protect against infection?
epiglottis |
|
nasal cavity |
|
trachea |
|
pharynx |
After air enters through the nose, it passes through the nasal cavity which filters, moistens, and warms it. Further filtering takes place in the pharynx, which also helps protect against infection, and then in the trachea which is just past the epiglottis, responsible for preventing food from entering the airway.
