2

The small intestine utilizes enzymes produced where?

66% Answer Correctly

liver

small intestine

pancreas

all of these are correct


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.


3

Meteoroids, meteors and meteorites are categorized based on which of the following?

45% Answer Correctly

their temperature

their size

their density

their location


Solution

Smaller rocks shed by asteroids and comets are called meteoroids. When these rocks reach Earth's atmosphere, they burn up in the mesosphere and become meteors. If a meteor manages to reach the Earth, it is called a meteorite.

61% Answer Correctly

gaseous methane, ammonia, and water

minerals


Solution

The Kuiper Belt is similar to the asteroid belt but much larger. Extending beyond the orbit of Neptune, it contains objects composed mostly of frozen methane, ammonia, and water. Most notably, the Kuiper Belt is home to Pluto, a dwarf planet that, until a 2006 reclassification, was considered the ninth planet of the solar system.
