LOS Quiz #6

A scientist is studying a phenomenon called "pyrolysis," which involves the breakdown of materials at high temperatures. Based on the prefix, what is most likely involved in this process?

• The use of water to dissolve substances

• The application of heat or fire to cause chemical change

• The movement of air to separate particles

• The use of light to trigger reactions

A biologist is researching "exoskeletons" in insects. What does the prefix "exo-" suggest about the location of the skeleton?

• The skeleton is located inside the body

• The skeleton is located outside the body

• The skeleton is only present during certain seasons

• The skeleton is made of multiple layers

A student is reading about "multicellular" organisms. What does the prefix "multi-" indicate about these organisms?

• They are made up of a single cell

• They are made up of many cells

• They are made up of equal-sized cells

• They are made up of cells that move quickly

A chemist is working with "isotonic" solutions in the lab. What does the prefix "iso-" tell you about the solutions being compared?

• The solutions have different concentrations

• The solutions have equal concentrations

• The solutions are below room temperature

• The solutions are above room temperature

A marine biologist is studying "subtidal" zones. Based on the prefix "sub-," where are these zones located?

• Above the high tide line

• Below the low tide line

• At the surface of the water

• In the middle of the ocean

A researcher is naming a new device that measures movement in animals. Which root from the list would be most appropriate to include in the device's name?

• Rupt

• Kine

• Pyro

• Iso

A geologist describes a volcanic eruption as "pyroclastic." Using your knowledge of scientific roots, what can you infer about the materials ejected during this eruption?

• They are primarily composed of water vapor

• They are fragments produced by intense heat or fire

• They are formed by the movement of tectonic plates

• They are created by the action of wind

A student encounters the word "subatomic" in a physics textbook. Using your understanding of prefixes, what does "subatomic" most likely refer to?

• Objects larger than atoms

• Objects found above the atomic level

• Objects smaller than atoms

• Objects with equal atomic mass

A biologist is investigating "endothermic" animals, which can regulate their own body temperature. Based on the prefix "endo-," what is a key characteristic of these animals?

• They rely on external sources for heat

• They generate heat internally to maintain body temperature

• They break down food outside their bodies

• They move rapidly to stay warm

A seismologist reports that an earthquake caused a "rupture" along a fault line. Using your understanding of the root "rupt," what most likely happened to the Earth's surface at that location?

• The surface was covered by volcanic ash

• The surface was split or broken apart

• The surface was eroded by water

• The surface was compressed into a new shape
