The energy posessed by a thrown baseball is an example of what kind of energy?
potential |
|
kinetic |
|
gravitational |
|

Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.
In the pancreas, lipase converts fat to:
glycerol and fatty acids |
|
complex carbohydrates |
|
amino acids |
|
simple sugars |
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 respiratory and circulatory systems are similar in that they:
transport nutrients |
|
deoxygenate blood |
|
transport oxygen |
|
add carbon dioxide |
Like the respiratory system, the circulatory system serves to transport oxygen throughout the body while removing carbon dioxide. In addition, the circulatory system transports nutrients from the digestive system.
Molecules and atoms that are inputs to a chemical reaction are known as which of the following?
reactants |
|
fuel |
|
components |
|
products |
During a chemical reaction molecules and atoms (reactants) are rearranged into new combinations that result in new kinds of atoms or molecules (products).
What kind of weather front is likely to create clouds and storms?
temperate front |
|
warm front |
|
cold front |
|
stationary front |
A warm front is the boundary between warm and cool (or cold) air when the warm air is replacing the cold air. Warm air at the surface pushes above the cool air mass creating clouds and storms.
