An element in the physical state of __________ maintains a constant volume but their shape depends upon the shape of their container.
plasma |
|
solid |
|
gas |
|
liquid |
In the liquid state, molecules flow freely around each other and exist at a higher temperature range than the same substance in a solid state. Liquids maintain a constant volume but their shape depends upon the shape of their container.
In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:
water |
|
sugar |
|
mitochondria |
|
oxygen |
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.
The large intestine does which of the following?
breaks down proteins |
|
processes the physical waste produced by digestion |
|
breaks down fats |
|
breaks down starches |
The large intestine (colon) follows the small intestine and processes the physical waste produced by digestion, absorbing water and minerials that remain back into the body. Solid waste is then stored in the rectum while liquid waste is stored in the bladder.
When two air masses meet and neither is displaced, what kind of front is present?
cold |
|
stationary |
|
occluded |
|

When two air masses meet and neither is displaced, a stationary front is created. Stationary fronts often cause persistent cloudy wet weather.
