No.... the weight of a substance is the mass of the substance multiplied with the acceleration due to gravity on it.
The spine is the indicator of stature
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein synthesis. In eukaryotic cells, each class of RNA has its own polymerase, whereas in prokaryotic cells, a single RNA polymerase synthesizes the different class of RNA. Other types of RNA also exist but are not as well understood, although they appear to play regulatory roles in gene expression and also be involved in protection against invading viruses.
A)Movement
Tress or plants can't move they can grow, reproduce and evolve but not move.
A species that is not native to an ecosystem but is introduced artificially. Usually cause harm to the native species in the area.
