In the pancreas, lipase converts fat to:
amino acids |
|
glycerol and fatty acids |
|
simple sugars |
|
complex carbohydrates |
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.
When two air masses meet and neither is displaced, what kind of front is present?
cold |
|

To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)
An asteroid belt holds many of the asteroids in our solar system. It is located between the orbits of which planets?
Mars and Jupiter |
|
Mercury and Venus |
|
Jupiter and Saturn |
|
Mars and Earth |
The solar system also contains over a million rocky fragments of at least 1km in diameter called asteroids as well as millions more with smaller diameters. Many of these asteroids are an asteroid belt between the orbits of Mars and Jupiter.
