What part of the brain is responsible for for balance, movement, and muscle coordination?
cerebellum |
|
brainstem |
|
medulla |
|
cerebrum |
The cerebellum is a large cluster of nerves at the base of the brain that's responsible for balance, movement, and muscle coordination.
In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:
oxygen |
|
mitochondria |
|
water |
|
sugar |
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 gravitational interaction of Earth and the Moon is responsible for which of these?
day and night cycle |
|
seasons |
|
the northern lights |
|
tides |
Tides are caused by the gravitational interaction of Earth and the Moon.
Cirrus clouds generally occur in what kind of weather?
freezing |
|
fair |
|
stormy |
|
hot |
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.
As part of the carbon cycle, plants release carbon into the atmosphere through which process?
evaporation |
|
photosynthesis |
|
decomposition |
|
sedimentation |
The carbon cycle represents the ciruit of carbon through Earth's ecosystem. Carbon dioxide (CO2) in the atmosphere is absorbed by plants through photosynthesis. Plants then die and release carbon back into the atmosphere during decomposition or are eaten by animals who breathe (respiration) the carbon into the atmosphere they exhale and produce waste which also releases carbon as it decays.
