Which of the following does not represent the freezing point of water?
273K |
|
32°F |
|
0°C |
|
0°F |
The Fahrenheit scale fixes the freezing point of water at 32°F, the Celsuis scale at 0°C, and the Kelvin scale at 273K.
Convert 5C° to F°.
-23 |
|
27 |
|
37 |
|
41 |
To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)
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.
Which of the following temperatures is least like the others?
32°F |
|
0K |
|
-273°C |
|
absolute zero |
Absolute zero is the coldest possible temperature in the universe. In the Kelvin scale, absolute zero is 0K and in the Celsius scale it is -273°C.

plants |
|
minerals |
|
habitats |
|
animals |
