Which of the following represents the largest value?
1 cL |
|
1 kL |
|
1 mL |
|
1 ML |
Mega (M) is 106, kilo (k) is 103, centi (c) is 10-2, milli (m) is 10-3 so 1 ML represents the largest value.
Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of:
1 m/s2 to a mass of 1 kg |
|
1 m/s to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg/s2 |
|
1 mph to a mass of 1 kg |
Weight is a force that describes the attraction of gravity on an object. Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of 1 m/s2 to a mass of 1 kg.
Antigens in the blood determine:
blood oxygen capacity |
|
blood type |
|
negative or positive status |
|
Rh factor |
Blood is categorized into four different types (A, B, AB, and O) based on the type of antigens found on the outside of the red blood cells. Additionally, each type can be negative or positive based on whether or not the cells have an antigen called the Rh factor.
In fermentation, what replaces oxygen in anaerobic respiration?
water |
|
ascorbic acid or peptides |
|
lactic acid or alcohol |
|
starches |
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.
Scavengers break down the dead bodies of plants and animals into which of the following?
carrion |
|
simple nutrients |
|
complex carbohydrates |
|
producers |
Like decomposers, scavengers also break down the dead bodies of plants and animals into simple nutrients. The difference is that scavengers operate on much larger refuse and dead animals (carrion). Decomposers then consume the much smaller particles left over by the scavengers.
