During digestion, where is digested food absorbed into the blood stream?
large intestine |
|
stomach |
|
small intestine |
|
pancreas |
The small intestine is where most digestion takes place. As food travels along the small intestine it gets broken down completely by enzymes secreted from the walls. These enzymes are produced in the small intestine as well as in the pancreas and liver. After the enzymes break down the food, the resulting substances are then absorbed into the blood via capillaries in the small intestine walls.
In the classification of life, which of the following is not a kingdom?
plants |
|
bacteria |
|
fungi |
|
animals |
Below domain, life is classified into six kingdoms: plants, animals, archaebacteria, eubacteria, and fungi. The last kingdom, protists, include all microscopic organisms that are not bacteria, animals, plants or fungi. (Archaebacteria and eubacteria are sometimes combined into a single kingdom, monera.)
212°F is how many °C?
\(135 {5 \over 9}\) |
|
100 |
|
-100 |
|
0 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (212 - 32)\)
\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)
\(C° = {900 \over 9}\)
\(C° = 100\)
Which of the following states of matter exists at the lowest temperature?
solid |
|
liquid |
|
gas |
|
none of these |
Solids exist at a lower temperature than liquids which exist at a lower temperature than gases.
Scavengers break down the dead bodies of plants and animals into which of the following?
producers |
|
simple nutrients |
|
carrion |
|
complex carbohydrates |
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.
