Answer: a. Increasing the surface area for diffusion
Explanation:
When the air is inhaled through the nostrils, the air containing the oxygen the air diffuses inside the alveoli. The alveoli are the tiny sacs where air enters and exchange of gases takes place. From the alveoli the oxygen enters into the blood stream. The oxygen is utilized by the cells for respiration. The increase in network and number of the alveoli will increase the surface area for the diffusion of oxygen and hence, will speed up the respiration process.

Answer:
pfu/ml
Explanation:
Given -
Bacteriophage dilution
ml
Volume of bacteria and plate with top agar
ml
Number of plaques
pfu
Dilution (d) 
Final concentration of phage stock is equal to

Where pfu is the count of plaques
d is the dilution and v is the volume
Substituting the given values, we get -
