Surfactants work by select one: a. coating the organism preventing interaction with its environment. b. blocking transport into the organism. c. blocking transport out from the organism. d. disrupting membrane integrity.

The correct answer will be option-D

Explanation:

Surfactants are the complex amphiphilic compounds which reduce or lower the surface tension between the two states that is liquid-liquid or solid-liquid.  

The surfactants arrange themselves in a state that their hydrophobic part is exposed in the air whereas their hydrophilic part is in the water.

The biosurfactants are produced by the micro-organisms which are considered superior emulsifiers as compared to the synthetic surfactants. Their amphiphilicity allows the insertion of the surfactant into the membrane which disrupts the integrity of the membrane.

Thus, option-D is the correct answer.

bal is blood alcohol level. bac will normally be higher in a person with more body fat. so the answer to your question would be, as body fat decreases, the increasing rate of bal decreases.
