What is the effect of an emulsifier on the digestion of lipids
snow_lady [41]

Answer:

Emulsifier generally reduces the surface tension of the lipid  there by helping in the digestion of the lipid molecules.

Explanation:

Bile that is secreted from liver act as emulsifier because the bile helps in the break down of lipid into small molecules to form micelle thereby reducing the surface tension of the lipid molecules.

                  Due the formation of micelle the broken down lipid molecules binds to the active site of the lipase enzyme and get digested to form fatty acid and glycerol.

           Beside digestion Emulsifier Bile also helps in the absoption of lipid from the small intestine.

Andrei [34K]

Answer:

<em>The correct option is D) immigration</em>

Explanation:

Immigration can be described as the movement of an organism to another place for living. As the scenario in the question tells, the population of the endangered Philippine eagle could be seen only in one place hence we can say that the immigration rate of these organisms was zero because they could not be seen in any other place.

Other option, like option B, cannot be correct because mortality refers to the death rate and obviously many organisms of the species died due to which it became endangered.

Lesechka [4]

The Hershey–Chase experiment was based on a bacteriophage T2 (a virus), to that DNA is the genetic material. Bacteriophage T2 attacks bacterium and makes its copies. Based on the experiment, Hershey and Chase deduced that it is the DNA of virus enters bacteria to make virus copies. To trace viral DNA, Hershey and Chase label DNA with ³²P (radioisotope of phosphorus) because phosphorus is not present in most of the proteins.
