1

Which of the following members of the food chain are most alike?

65% Answer Correctly

primary consumers and omnivores

herbivores and autotrophs

scavengers and decomposers

producers and tertiary consumers


Solution

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.


2

-40°F is how many °C?

40% Answer Correctly

-40

-8

\(-{40 \over 9}\)

\({40 \over 9}\)


Solution

The formula to convert from F° to C° is:

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (-40 - 32)\)

\(C° = {5 \over 9} (-72) = {{-72 \times 5} \over 9}\)

\(C° = {-360 \over 9}\)

\(C° = -40\)


3

The crust and upper mantle of the earth is called the:

62% Answer Correctly

hydrosphere

lithosphere

geosphere

atmosphere


Solution

The biosphere is the global ecological system integrating all living beings and their relationships. This includes their interactions with the lithosphere (the rigid outer part of the earth, consisting of the crust and upper mantle), hydrosphere (all surface water), and atmosphere (the envelope of gases surrounding the planet).


4

Poor balance could indicate an issue with which part of the nervous system?

64% Answer Correctly

cerebrum

cerebellum

medulla

spinal cord


Solution

The cerebellum is a large cluster of nerves at the base of the brain that's responsible for balance, movement, and muscle coordination.


5

Most digestion takes place where?

65% Answer Correctly

mouth

large intestine

stomach

small intestine


Solution

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.
