Plant cells may generate energy through which of the following?
photosynthesis |
|
aerobic respiration |
|
all of these |
|
anaerobic respiration |
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.
Changes to an object's speed or direction of motion are caused by which of the following?
power |
|
work |
|
kinetic energy |
|
a force |
Force is applied to change an object's speed or direction of motion.
Water coming to a boil on a stove, ice melting, and steam from a cup of coffee are all examples of which of the following?
reflection |
|
convection |
|
radiation |
|
conduction |
Convection is the transfer of heat by the circulation or movement of the heated parts of a liquid or gas.
In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:
mitochondria |
|
water |
|
oxygen |
|
sugar |

Cirrus clouds generally occur in what kind of weather?
freezing |
|
fair |
|
hot |
|
stormy |
Cirrus clouds are thin, wispy high-altitude clouds composed of ice crystals that originate from the freezing of supercooled water droplets. Cirrus clouds generally occur in fair weather and point in the direction of air movement at their elevation.
