In what way are all living organisms on earth similar

All living organism on earths are similar on the basis of life process and chemical composition of the genetic material.

Explanation:

All living organisms perform the basic life process like respiration, digestion, reproduction and excretion. The simple basic organisation of living organisms is the cell. Cell is the structural and functional unit of all the living organism.

All living organisms are made up of similar types of nucleic acids. DNA is present as genetic material in all the organism except some viruses. Living organism present on earth follows the molecular central dogma that refers the process of replication, transcription and translation.

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.

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave
