Trilobites are marine organisms that became extinct about 250 million years ago. There were as many as 25,000 species of trilobites, and their fossils are found all over the world, in mountains, deserts, grasslands, and rolling hills. Based on the information given, you can conclude that —
trilobites could live in many different habitats and ecosystems
some of the 25,000 species of trilobites lived on land
trilobite fossils formed mostly in high mountain areas
the locations where the fossils are found were once under water
Answer explanation
Trilobites were marine organisms, and their fossils are found in diverse locations. This suggests that these areas were once underwater, as trilobites lived in marine environments.

Lemonade is a solution that can be made by dissolving powdered lemonade mix in a pitcher of water. If the powdered lemonade mix is seen sinking to the bottom of the pitcher of water, what is the most likely explanation for this?
The pitcher needs ice in it for the lemonade mix to dissolve in the water.
Not enough time has passed for the lemonade mix to dissolve in the water.
The lemonade mix must be stirred into the water for it to dissolve.
The lemonade mix was not able to dissolve and form a solution with the water this time.
Answer explanation
The lemonade mix must be stirred into the water for it to dissolve. Simply adding the mix without stirring will cause it to sink instead of dissolving, as it needs agitation to properly integrate into the water.

What physical properties do all of the objects have in common?
A. Physical state and relative density
B. Temperature and relative density
C. Physical state and magnetism
D. Mass and temperature

A plastic tub is filled halfway with water, and a rubber duck is placed on top of the water to float, demonstrating how waves in water transfer energy. How could this model be improved?
A larger rubber duck could be used.
The tub could be filled with less water.
Air could be blown through a straw toward the surface of the water to create waves to move the rubber duck.
The tub could be filled with deeper water.
Answer explanation
Blowing air through a straw creates waves, effectively demonstrating energy transfer in water. This method enhances the model by actively generating movement, unlike the other options which do not improve wave generation.
