What is all matter in the universe composed of (multiple choice)?

Question

A. cells
B. molecules
C. atoms
D. carbon

Answer 1

I think the answer for your question is (C)= atoms because you are saying the UNIVERSE, if you were saying the living organisms I would say cells, compounds= molecules and organic compounds = carbon.

Answer 2

Matter makes up everything in the universe, so you have to think does *insert answer* make up everything in the universe?

A. Cells - can't be right because cells make up all living things. Plastic staplers were never living so they can't be made up of cells.

B. Molecules - Molecules are, in short, two or more atoms. The thing is though, just one atom is enough to qualify as matter, so this is a pretty good answer but not the best.

C. ATOMS - I'd say this is the right answer. From Wikipedia "Matter is the stuff which things are made of and consists of chemical substances. These are made of atoms, which are made of protons, neutrons and electrons."

D. Carbon is an element which is in lots of things in earth but not everything in the universe. There isn't an Carbon in NaCl (more commonly known as table salt) and many other compounds.

So, your best bet would be atoms with the choices given

Answer 3

it's been a long time but I would say atoms. Individual atoms make up molecules. Carbon is a molecule. And Cells are made up of molecules. But you should definitiely do some of the work yourself.

Answer 4

I know it is not one of your options, but most matter is empty space. The weight of a proton is given the arbtrary equivelent weight of 1 AMU or atomic mass unit. If my memory is correct (college was so long ago), an electron is 1/1087 AMU.The distance between the proton and the elctron is huge compared to the size of the particles themselves. This is true of any atom. therefore, all matter is mostly empty space, it just does not appear that way. Perception eh?

Answer 5

C, atoms are part of everything in the universe including the wrong answers of A,B, and D.

Answer 6

I'm guessing the answer they are looking for is C. Atoms.

However - that is incorrect. The most common state of matter in the universe is plasma:
http://en.wikipedia.org/wiki/State_of_matter
And plasma is *ionised* matter (ions are atoms that have either lost or gained electrons, and so are charged):
http://en.wikipedia.org/wiki/Ionization

The reason why plasma is more common than the other states of matter (solid, liquid, gas) is because *stars* are made of ions.

So all matter in the universe is composed of
E. subatomic particles.
Because even ions are made of protons, electrons, neutrons, etc.

Answer 7

E. None of the above. There are forms of matter (typically in extreme environments such as within neutron stars) that are not composed of atoms.

Answer 8

All known matter is made up of atoms, but 80 - 90 % of matter is believed to be dark matter. But we don't know the composition of dark matter.

Answer 9

C. atoms

Answer 10

The correct answer is C if you're in a simple high school class.
Once you get up to college and learn quantum/astrophysics, things get complicated ;)
