Examples of secondary consumers include:
grasshoppers |
|
plankton |
|
wolves |

In fermentation, what replaces oxygen in anaerobic respiration?
ascorbic acid or peptides |
|
starches |
|
water |
|
lactic acid or alcohol |
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.
The formula for acceleration is which of the following?
\(\vec{a} = { \vec{F} \over m }\) |
|
\(\vec{a} = { m \over \vec{F} }\) |
|
\(\vec{a} = { m \over F }\) |
|
\(\vec{a} = \vec{F} m\) |
Newton's second law of motion leads to the formula for acceleration which is a measure of the rate of change of velocity per unit time and, if you solve for positive acceleration, reveals how much net force is needed to overcome an object's mass. The formula for acceleration is \(\vec{a} = { \vec{F} \over m }\) or, solving for force, \(\vec{F} = m\vec{a}\).
