Cellular fermentation takes place:
in the presence of oxygen |
|
anaerobically |
|
in plant cells |
|
aerobically |
If no oxygen is present, cellular respiration is anaerobic and will result in fermentation where either lactic acid or alcohol is used instead of oxygen.
In the water cycle, infiltration is most closely related to:
oceans |
|
runoff |
|
water table |
|
rivers |
The water then accumulates as runoff and eventually returns to bodies of water or is absorbed into the Earth (infiltration) and becomes part of the water table, an underground resevoir of fresh water.
A large naturally occurring community of flora and fauna occupying a major habitat is:
a food chain |
|
a biome |
|
a population |
|
a community |
A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).

To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(0) + 32\)
\(F° = 0 + 32 = 32\)
Which of the following describes the Earth's mantle?
dense |
|
hot |
|
makes up most of Earth's volume |
|
all of these |
Mantle makes up 84% of the Earth's volume and has an average thickness of approximately 1,800 miles (2,900 km). It is dense, hot, and primarily solid although in places it behaves more like a viscous fluid as the plates of the upper mantle and crust gradually "float" along its circumference.
