In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:
mitochondria |
|
oxygen |
|
sugar |
|
water |
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 transfer of heat by the circulation or movement of the heated parts of a liquid or gas is called:
conduction |
|
convection |
|
diffusion |
|
radiation |
Convection is the transfer of heat by the circulation or movement of the heated parts of a liquid or gas. Examples of heat transfer by convection include water coming to a boil on a stove, ice melting, and steam from a cup of coffee.
Which of the following states of matter exists at the highest temperature?
none of these |
|
solid |
|
liquid |
|
gas |
Solids exist at a lower temperature than liquids which exist at a lower temperature than gases.
When two air masses meet and neither is displaced, what kind of front is present?
warm |
|
occluded |
|
cold |
|
stationary |
When two air masses meet and neither is displaced, a stationary front is created. Stationary fronts often cause persistent cloudy wet weather.
The energy posessed by a ball on the window ledge of a tall building is an example of what kind of energy?
potential |
|
kinetic |
|
inherent |
|
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.
