Which of these digestive enzymes is not produced by the pancreas?
trypsin |
|
pancreatic amylase |
|
lipase |

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.

reproductive |
|
nervous |
|
digestive |
|
circulatory |
