[ALL of these]
Explanation
## Step1:There once more arises a question about Alveoli. Alveoli, as we know, are the tiny sacs within our lungs which allow for gaseous exchange, the quick and efficient transfer of oxygen and carbon dioxide between our lungs and bloodstream.## Step2:The first choice in question grapples with whether having 'a LARGE total SURFACE AREA' is an adaptation of alveoli for its tasks. Indeed, having a large surface area more broadly exposes the alveoli to oxygen, enhancing the capacity for oxygen diffusion into the bloodstream.## Step3:The next choice revolve around whether having 'a good BLOOD SUPPLY' forms another characteristic that helps a alveoli to accomplish what it sets to do. Supply of blood here is quite crucial, as this supply is what carries oxygen diffused through alveolar walls further to the various body cells.## Step4:The question then leaps to another adaptation - 'walls that are ONE CELL THICK.' This, too, is a vital characteristic. Mailnly because a thinner wall decreases the diffusion path length, the distance which oxygen and carbon dioxide needs to traverse. This consequently quickens the gas exchange process.### Considering above discussions we see, thankfully to the meticulous blueprint of the human body, Alveoli possess all three aforementioned traits:- a large surface area to facilitate gaseous exchange- an efficient blood supply to capture and transport this gaseous exchange to body cells- One-cell thick walls to restrict hindrances to this exchange's processes and quickly conduct it.
