Pull Of Gravity , that is why you have weight or else without gravitational pull you only have mass hence the equation w = mg
I believe its large blue vessel also known as vena cava
The Great Barrier Reef, located off of Australia’s eastern coast, is the largest coral reef ecosystem in the world. The reef covers an area over 300,000 square kilometers and includes a wide range of ocean depth, and it contains such biodiversity as to make it one of the most complex ecosystems on Earth. Much like any other ecosystem on Earth, the Great Barrier Reef relies on biotic and abiotic components to keep it functional and stable.
Explanation:
Central dogma represents the pathway in which the information encoded in the DNA flows into proteins.
The DNA is made up of the nucleotide monomers in which the nitrogenous bases are present as one of the constituents. These bases are present in the sequence are transcribed into the RNA molecule through the process of transcription.
The nitrogenous sequences in this RNA molecule are then translated into the proteins through the process of translation during which the sequence is read in pairs of three called "codons". A specific amino acid is attached to the peptide when the codons are read by the translation machinery and a protein is formed.
These proteins could perform various roles in organisms from physical to biochemical and thus the physical traits are controlled by the DNA.
Evolution, and the survival of the fittest the weak ones die off and the strong ones live and continue to reproduce
