diffusion is a critical process required for oxygen to leave the
alveoll of the lungs to enter the blood and for carbon dioxlde (a
waste gas) to leave the blood and enter the alveoll.
9. knowing what you know about how a substance travels in
diffusion, in order for oxygen to leave the alveoli and enter the
blood, there would be a (higher or lower ] concentration of
oxygen in the alveoli compared to the blood.
10. knowing what you know about how a substance travels in
diffusion, in order for carbon dioxide to leave the blood and enter the
alveoll, there would be a (higher or lower] concentration of
carbon dioxide in the alveoli compared to the blood.

11. explain your reasoning for questions #9 and #10.

it is a

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
