Answer:

All living things are made of cells

Cells form from previously existing cells

Explanation:

According to the Cell Theory, all forms of life are composed of one or more cells, whereby cells are the fundamental building blocks in all living organisms. All cells are composed of inorganic molecules (e.g., water) and carbon-based organic molecules (e.g., carbohydrates, lipids, nucleic acids, etc). All the new cells arise from the division of pre-existing cells. Louis Pasteur showed cells would only grow in broth if they are exposed to air (oxygen), thus refuting the idea of spontaneous generation. In multicellular eukaryotic organisms, these cells can be organized in tissues, organs and organ systems.

The other characteristics such as height and time of suspended grains depends on grain size, shape, and density, lift  & drag force and characteristics of wind such as velocity and turbulence.  

Hence, option B is correct
