Proteins seem better suited for storing genetic information because DNA is only made from 4 bases while proteins were made from 20 amino acids, Scientists thought that proteins could code for much greater variety in their amino acid sequence than DNA could in its nucleotide sequence.
False. Oxygen is absorbed in the alveoli sacs of the lungs.
Upon inhalation Air must first pass through the larynx and down to the trachea, which then splits off into two separate bronchial tubes, the bronchial tubes divide into smaller air passages known as the bronchi and those into even smaller bronchioles. The bronchioles end in tiny sacs called the alveoli which transfer the oxygen from the inhaled air to the bloodstream.
