  2. amount of substances used
  3. number of trials

The factors which have shown variation are as follows -

  1. molecule size (large starch molecules vs. small glucose molecules)
  2. whether the molecules diffused through the membrane (tubing)

Explanation

Some factors with in the experiments remained constant from the point of starting of the experiment to its end. While some factors were varied to study its impact on the experiment rate of progression or on the final product formed. Thus , out of the following given factors, the ones that remained constant are -

  1. material used as the membrane
  2. amount of substances used
  3. number of trials

The factors which have shown variation are as follows -

  1. molecule size (large starch molecules vs. small glucose molecules)

Emulsion of fatty acids is necessary to _____.
kap26 [50]

Answer:

c. increase the surface area available for hydrolysis by lipase

Explanation:

Emulsification of fats(fatty acid) is a chemical reaction where large molecules(globules) of fats are broken down into a smaller molecules (droplets) by the action of an emulsifier.

In the human body, emulsification takes places in the duodenum during the process of digestion of fats. When large fat molecules have been broken down into smaller fat molecules by action of an emulsifier called bile salts from the gall bladder, a larger surface area is created which makes it possible for the enzyme lipase from the pancreas to react with or act on fat molecules through the process of hydrolysis thereby converting the fats to fatty acids and glycerol for use by the body.
