3. a rock is placed in a graduated cylinder containing water, and the cylinder is covered to avoid evaporation. the next morning the water level has dropped by 5.65 no one has had access to the cylinder, and the cylinder has no leaks. what is the most likely explanation for what happened? (5pts

Hi! Some rocks are porous material, like a sponge, with lots of air pockets inside, so they can absorbe water. In this case, the water level dropped 5.65m because tha volume of water went inside the rock filling the air pockets. The water replaced the air, that flowed to the outside water as bubbles and then to the air above the water.  

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

the rearrangement of particles in a physical change. hope this
