Answer the following question given this paragraph: The main chemical components of living organisms are known as organic compounds . Organic compounds are molecules built around the element carbon (C). Living things are made up of very large molecules. These large molecules are called macromolecules because "macro" means large; they are made by smaller molecules bonding together. Our body gets these smaller molecules, the "building blocks" or monomers , of organic molecules from the food we eat. Which organic molecules do you recognize from the list below?. Q: Organic compounds are molecules built around what element? Choices: - helium - phosphorus - oxygen - carbon A:
(Answer)
carbon
Ques: Answer the following question given this paragraph: Geothermal energy is an excellent resource in some parts of the world.

Ques:Answer the following question given this paragraph: The majority of known elements are classified as metals. Metals are elements that are lustrous, or shiny. They are also good conductors of electricity and heat. Examples of metals include iron, gold, and copper. Fewer than 20 elements are classified as nonmetals. Nonmetals lack the properties of metals. Examples of nonmetals include oxygen, hydrogen, and sulfur. Certain other elements have properties of both metals and nonmetals. They are known as metalloids. Examples of metalloids include silicon and boron. Q: What are the three classifications of elements? Choices: - metals, non-metals and alkaloids - metals, metaloids, and alkaloids - alkaloids, metaloids, and non-metals - metals, non-metals and metaloids A:

Ans:
metals, non-metals and metaloids
