In fermentation, what replaces oxygen in anaerobic respiration?
starches |
|
water |
|
lactic acid or alcohol |
|
ascorbic acid or peptides |
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.
-40°F is how many °C?
\({40 \over 9}\) |
|
-40 |
|
-8 |
|
\(-{40 \over 9}\) |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (-40 - 32)\)
\(C° = {5 \over 9} (-72) = {{-72 \times 5} \over 9}\)
\(C° = {-360 \over 9}\)
\(C° = -40\)

A dominant trait will be expressed when paired with:
a recessive trait |
|
a dominant trait |
|
a chromosome |
|
a gene |
The traits represented by genes are inherited independently of each other (one from the male and one from the female gamete) and a trait can be dominant or recessive. A dominant trait will be expressed when paired with a recessive trait while two copies of a recessive trait (one from each parent) must be present for the recessive trait to be expressed.
