In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:
water |
|
oxygen |
|
sugar |
|
mitochondria |

Convert -20C° to F°.
-4 |
|
36 |
|
78 |
|
-36 |
To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(-20) + 32\)
\(F° = {-180 \over 5} + 32\)
\(F° = -36 + 32 = -4\)
