In fermentation, what replaces oxygen in anaerobic respiration?
starches |
|
lactic acid or alcohol |
|
water |
|
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.
The formula for acceleration is which of the following?
\(\vec{a} = { \vec{F} \over m }\) |
|
\(\vec{a} = { m \over F }\) |
|
\(\vec{a} = \vec{F} m\) |
|
\(\vec{a} = { m \over \vec{F} }\) |
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, \(\vec{F} = m\vec{a}\).
__________ and __________ pair to strengthen bones.
iron, calcium |
|
vitamin D, magnesium |
|
calcium, vitamin A |
|
vitamin D, calcium |
Vitamin D helps calcium strengthen bones while also aiding muscle, nerve, and immune system function.
As part of digestion, the liver produces bile which breaks down:
fat |
|
protein |
|
sugars |
|
starches |
The liver produces bile which emulsifies (separates) fat.
In cell biology, cytokinesis results in two separate:
chromatids |
|
nuclei |
|
cells |
|
chromosomes |
During cell division, the cytokinesis phase occurs when cytoplasm and cell membranes complete their separation resulting in two separate cells.
