Which of these digestive enzymes is not produced by the pancreas?
lipase |
|
pancreatic amylase |
|
gastric acid |
|
trypsin |
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.
Which is the proper order of Earth's atmospheric layers from the surface up to space?
mesosphere, thermosphere, stratosphere, troposphere |
|
troposphere, stratosphere, mesosphere, thermosphere |
|
thermosphere, mesosphere, stratosphere, troposphere |
|
stratosphere, troposphere, mesosphere, thermosphere |
The troposphere is the closest layer to Earth, followed by the stratosphere, mesosphere, and finally the thermosphere which borders space.

The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (50 - 32)\)
\(C° = {5 \over 9} (18)\)
\(C° = {90 \over 9}\)
\(C° = 10\)
What part of the food chain serves only as food for other organisms?
primary consumers |
|
secondary consumers |
|
producers |
|
decomposers |
Producers (autotrophs) serve as a food source for other organisms. Typical producers are plants that can make their own food through photosynthesis and certain bacteria that are capable of converting inorganic substances into food through chemosynthesis
Heredity is the passing on of physical or mental characteristics genetically from one __________ to another.
family |
|
species |
|
