Question

in the 1700s, a French scientist, Antoine Lavoisier, gained new experimental information by reacting a metal and an acid. His observation of the results seemed to show that much of the metal had been lost in the chemical reaction. Upon weighing the products, the total amounts of materials had not changed during the reaction.This research resulted in the law of conservation of mass. This law also applies to biology, because the materials we are made of are _________ that change forms, but aren't truly lost through biochemical reactions.

Answer 1

Matter.

Step-by-step explanation:

Matter is any thing that occupies space and has its own mass. All things are made of matter whether living or non living. Matter can neither be created nor destroyed during the reactions.

The four biomolecules carbohydrates, proteins, lipids an nucleic acids are made of matter. Matter are never lost but only changes its form from one state to the another state. The three main states of matter are solid, liquid and gas.

Thus, the answer is matter.

Answer 2

Matter

Step-by-step explanation:

Matter refers to the atoms, molecules, compounds which we are composed of and our surrounding is made of.

The law of conservation of mass was proposed by the Antoine Lavoisier who stated that mass neither gained nor lost but changed its form from one form to another in his experiments.

The same law of conservation of mass applies to the biological organisms as like living things they are also made up of the matter. The metabolism of the chemical reaction taking place in the living organism is evidence of the law of conservation of mass.

Thus, the matter is correct.
