A graduated cylinder contains 10mL of water. A rock is dropped into the cylinder and the water level rises to 17mL. What is the volume of the rock? (hint: 1mL = 1cm³)

Explanation:

1 cubic centimeter = 1 milliliter

You can measure the volume of a rock using cubic centimeters because rocks do not have a defined shaped so you have to use water displacement to find the volume of a rock. If you had a defined shape there are different methods but for an undefined shape( rocks) you use this method.

To solve all you have to do is know how much there was in the container without the rock then how much there was with the rock. Then you take the total and subtract the original measurement you had.

17-10=7 mL or 7 cubic centimeters

7mL

Explanation:

17-10=7

you have to subtract the initial volume to final volume

the element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.

explanation:

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
