Arab cultures charted planets in the Dark Ages. Europeans helped establish the Sun-centered model of the solar system during the Renaissance. Russia and the U. S.A have discovered new features on planets using spacecraft in modern times. This is an example of
A.
many cultures arguing about how the solar system works and all of their contributions being worthless.

B.
cultures wasting time by doing the same thing over and over throughout history.

C.
how contributions by many different cultures throughout history have advanced our understanding of the solar system.

D.
modern technology proving that earlier cultures could not contribute to our understanding of the solar system.

Its C how contributions by many different cultures throughout history have advanced our understanding of the solar system.

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
