Parker has a toy car he has made out of plastic building blocks. He breaks it apart so he can build something different with the same blocks. When he breaks the blocks apart, which stage of the carbon cycle is he best demonstrating? A:carbon atoms dissolving in the oceans

B:producers removing carbon from the atmosphere

C:organisms decay and carbon atoms return to the soil

D:consumers use carbon atoms to build body structures

C

Because Parker is using the recycled blocks (carbon atoms) and essentially returning them to their original state (which is "the soil"). When the clocks break apart, that is the organisms decaying.

h

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
