Question

Choose which are qualities common to all respiratory surfaces.

a. The respiratory surface into contact with air or water
b. The surface has a moist membrance
c. The respiratory surface interfaces with a closed circulatory
d. The surface is within either paired or unpaired lungs
e. Carbon dioxide diffuses from the enviorment into the animal body across the respiratory surface
f. Gas exchange occurs across a large surface area
g. Oxygen diffuses from the animal body into the enviorment across the respiratory surface

Answer 1

The options B and F are common for all respiratory surfaces.

Step-by-step explanation:

All respiratory surfaces are involved in some form of gas exchange.

So firstly, the respiratory surface needs to have a moist membrane to be able to get the gases to diffuse properly. Option B is correct.

The surface area must be large and the surface of the respiratory system must be thin so that the maximum amount of gas can be diffused for increased efficiency. Option F is correct.

I hope this answer helps.
