These clouds grow upward and can develop into cumulonimbus or thunderstorm clouds.
stratus clouds |
|
cumulus clouds |
|
cirrus clouds |
|
nimbus clouds |
Cumulus clouds are large, puffy, mid-altitude clouds with a flat base and a rounded top. These clouds grow upward and can develop into a cumulonimbus or thunderstorm cloud.
In the pancreas, lipase converts fat to:
simple sugars |
|
glycerol and fatty acids |
|
complex carbohydrates |
|
amino acids |
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 angle of reflection is equal to which the following?
90° |
|
refractive index |
|
angle of incidence |
|
focal point |
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.
Large, puffy, mid-altitude clouds with a flat base and a rounded top describe which of the following?
cumulus clouds |
|
stratus clouds |
|
fog |
|
cirrus clouds |
Cumulus clouds are large, puffy, mid-altitude clouds with a flat base and a rounded top. These clouds grow upward and can develop into a cumulonimbus or thunderstorm cloud.
Water has a refractive index of 1.33. Which of the following is true?
light travels 1.33 times slower in a vacuum than it does in water |
|
light is 1.33 times dimmer in a vacuum than it is in water |
|
light travels 1.33 times faster in a vacuum than it does in water |
|
light is 1.33 times brighter in a vacuum than it is in water |
The speed of light varies based on the material that the waves are passing through. The refractive index of a material indicates how easily light travels through it compared to how easily light travels through a vacuum. For example, the refractive index of water is 1.33, meaning that light travels 1.33 times faster in a vacuum than it does in water.
