Julio wants to find the volume of a small pebble. he drops it into a graduated cylinder filled with 30.0 ml of water.

how is julio most likely trying to determine the pebble’s volume?

by calculating water density
by calculating water displacement
by measuring the pebble’s dimensions
by measuring the pebble’s mass

Option B, by calculating water displacement

Explanation:

As per the Archimedes Principle, the volume of the amount of water displaced by an object when it is placed in water is equal to volume of the object.

By this logic, Julio in this experiment is trying to measure the amount of displaced water . Once she gets the quantity of displaced water , she can easily deduce the volume of small pebble as volume of displaced water will be equal to the volume of small pebble.

Hence, Option B is correct

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.

i believe it is c: genes for body color and wing size are inherited separately from each parent.
