I biome is made up of naturally occurring flora and fauna. Fauna is which of the following?
animals |
|
habitats |
|
plants |
|
minerals |
A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).
Arteries carry __________ blood at __________ pressure.
deoxygenated, low |
|
deoxygenated, high |
|
oxygenated, high |
|
oxygenated, low |
Veins carry blood back to the heart from the body. While arteries are thick-walled because they carry oxygenated blood at high pressure, veins are comparatively thin-walled as they carry low-pressure deoxygenated blood. Like the heart, veins contain valves to prevent blood backflow.
In the foood chain, producers serve as a food source for other organisms. Typical producers are plants that can make their own food through photosynthesis and certain bacteria that are capable of converting inorganic substances into food through:
chemosynthesis |
|
decomposition |
|
photosynthesis |
|
autotrophs |

-40°F is how many °C?
-40 |
|
\(-{40 \over 9}\) |
|
-8 |
|
\({40 \over 9}\) |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (-40 - 32)\)
\(C° = {5 \over 9} (-72) = {{-72 \times 5} \over 9}\)
\(C° = {-360 \over 9}\)
\(C° = -40\)
The energy posessed by a ball on the window ledge of a tall building is an example of what kind of energy?
gravitational |
|
inherent |
|
potential |
|
kinetic |
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.
