Covalent bonds allow carbon atoms to form numerous compounds.
Answer: Option D.
The atoms and molecules of the liquid water are moving, and the atoms and molecules of the
table are not moving.
Explanation:
The atoms and molecules of the liquid water are moving, and the atoms and molecules of the table are not moving and this is because the atoms and molecules of liquid water are closely packed together and they collide to each other often, thereby moving in random motion in all directions.
The molecules of solid cannot move because they are closely packed together and there is a very strong of attraction which make them to only vibrate and not move and this make solid to have definite shape.
Microtubules are tiny, hollow, bead-like tubular structures that help cells maintain their shape. Along with microfilaments and intermediate filaments, they form the cytoskeleton of the cell, as well as participate in a variety of motor functions for the cell.
