Which of the following does not filter air as part of the respiratory system?
nasal cavity |
|
pharynx |
|
trachea |
|
epiglottis |
After air enters through the nose, it passes through the nasal cavity which filters, moistens, and warms it.

Which of these layers is found directly below the Earth's crust?
continents |
|
outer core |
|
mantle |
|
inner core |
The crust is the Earth's outermost layer and is divided into oceanic and continental types. Oceanic crust is 3 miles (5 km) to 6 miles (10 km) thick and is composed primarily of denser rock. Continental crust is 20 to 30 miles (30 to 50 km) thick and composed primarily of less dense rock. The crust makes up approximately one percent of the Earth's total volume.
Which of these is not a phase in cell division?
interphase |
|
cytokinesis |
|
megaphase |
|
anaphase |
