Viruses have some, but not all, of the characteristics of living things.
Organisms may not exhibit all of the characteristics of life at all times.
Reproduction can occur asexually or sexually in living things.
Reproduction is defined as an increase in the size of an organism.
Living things store metabolic energy in the form of chemicals such as ATP.

Rate this question:
Osmosis stops when the system reaches equilibrium
During osmosis, water crosses to the side of the membrane with a lower solute concentration.
Osmosis requires a selectively permeable membrane
Cells placed in hypotonic solutions will gain water
Crenation results when cells are placed in a hypertonic solution.
Rate this question:
Treponema is an example of a bacterium that has an endoflagellum.
Prokaryotic flagella are anchored to the cell wall by means of the basal body.
A ʺrunʺ results from counterclockwise movement of the flagellum.
Prokaryotic flagella are composed of tubulin.
Prokaryotic flagella can rotate 360 degrees.
