It consists of the alveolar wall, the capillary wall, and their basement membranes.
Rarefaction in terms of ecology can be defined as a technique used to assess species richness from the results of sampling.

Hence, the correct answer is: option A-Creating a representative sample
False ; a dominant trait has the ability to do that & is represented with a capital letter
