Many eukaryotic cells can be grown in tissue culture in the laboratory. Suppose you have two tissue cultures, one in G1 phase and one in S phase. How would you determine which culture was in G, and which was in S?

I could look for growth and synthesis of proteins and other macromolecules as well as increase in organelles, which would show a culture in G1. DNA being synthesized would show in cells in the S phase.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
