Plant cells may generate energy through which of the following?
photosynthesis |
|
aerobic respiration |
|
anaerobic respiration |
|
all of these |
Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.
In the pancreas, lipase converts fat to:
simple sugars |
|
complex carbohydrates |
|
amino acids |
|
glycerol and fatty 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.
"For every action, there is an equal and opposite reaction." This describes which of Newton's laws of motion?
second |
|
first |
|
third |
|
fourth |
Newton's third law of motion states that For every action, there is an equal and opposite reaction. When an object exerts a force on another object, the second object exerts a force of equal magnitude in the opposite direction on the first object.
Herbivores are __________ that subsist on producers like plants and fungus.
primary consumers |
|
scavengers |
|
tertiary consumers |
|
secondary consumers |
Primary consumers (herbivores) subsist on producers like plants and fungus. Examples are grasshoppers, cows, and plankton.
Convert -20C° to F°.

To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(-20) + 32\)
\(F° = {-180 \over 5} + 32\)
\(F° = -36 + 32 = -4\)
