The same proteins are found in all different organisms.
The same proteins are found in all different organisms.

The proteins of different organisms are different, but they are all made of the same set of 20 different parts.
The proteins of different organisms are different, but they are all made of the same set of 20 different parts.

All animals have the same proteins and all plants have the same proteins, but animal proteins are different from plant proteins.

Answer 1

The statement that is true about the proteins found in different organisms is:

The proteins of different organisms are different, but they are all made of the same set of 20 different parts.

This is because all proteins are made up of 20 different amino acids, which are the building blocks of proteins. However, the specific sequences and combinations of these amino acids differ across different species, leading to a diverse array of proteins with varied functions.
