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

number of electrons orbiting the nucleus |
The Periodic Table of the Elements categorizes elements primarily by the number of protons in their nucleus (atomic number) and secondarily by the characteristics they exhibit.
The angle of reflection is equal to which the following?
focal point |
|
90° |
|
angle of incidence |
|
refractive index |
The law of reflection specifies how waves, including light waves, bounce off of surfaces. Specifically, the angle of incidence of the approaching wave is equal to the angle of reflection of the reflected wave as measured from a line perpendicular (90°) to the surface.
