During digestion, where is digested food absorbed into the blood stream?
large intestine |
|
pancreas |
|
small intestine |
|
stomach |
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.
What part of the brain is responsible for for balance, movement, and muscle coordination?
medulla |
|
cerebellum |
|
brainstem |
|
cerebrum |
The cerebellum is a large cluster of nerves at the base of the brain that's responsible for balance, movement, and muscle coordination.
In the food chain, bacteria and fungi convert the organic matter in the dead bodies of plants and animals into simple nutrients. Bacteria and fungi are:
decomposers |
|
primary consumers |
|
scavengers |
|
producers |
Decomposers (saprotrophs) are organisms such as bacteria and fungi that break down the organic matter in the dead bodies of plants and animals into simple nutrients.
Poor balance could indicate an issue with which part of the nervous system?
cerebrum |
|
medulla |
|
cerebellum |
|
spinal cord |
The cerebellum is a large cluster of nerves at the base of the brain that's responsible for balance, movement, and muscle coordination.
Sound travels fastest through which of the following media?
water |
|
air |
|
vacuum |
|
metal |
The speed of a sound wave will vary with the medium. Sound travels fastest through media that has particles that are very close together, like metal. Thus, it travels faster through water than through air and doesn't travel at all through a vacuum (there are no particles in empty space to vibrate).
