They are all assembled from a nucleic acid code
they all use the same set of nucleotides.
Living organisms on Earth are similar in that they are all composed of cells, they require energy for survival, they can reproduce, and they can respond and adapt to their environment.
cellular function.
All organisms use the same genetic code.Living organisms are made of the same components as all other matter, organisms that inhabit the earth at any one time they are all assembled from a nucleic acid code
Archaea are considered to be the group of organisms most similar to the first cells on Earth. They are single-celled microorganisms that have simple cell structures and thrive in extreme environments, similar to the conditions present on early Earth.
They are similar because they are all part of the earth. Another way they are similar is because they are all nonliving. ( in science called abiotic) The last way is that there are organisms living in or on them. Sorry this answer is not very specific. I had a really good answer for you but it got deleted. I hope this helps you!

No planets are similar but there is a moon. Titan, one of Jupiter's moons, is very similar to Earth.
All living organisms' bodies are made to reproduce. For example, plants pollinate, terrestrial organisms have penis' and vaginas and even bacteria multiply a-sexually.
well earth
they all use the same set of nucleotides APEX
All living organisms on earth are similar because all of them possess a genetic code. Plants, animals, mosses, corals, and bacteria all have genes which define what they will become and their traits. For example a human (homo sapien) and a banana (Musa paradisiaca) share 30% of their genetic material.
