1. Passive transport is one of the processes that occur at the cell membrane in a cell. Which of the following is an example of passive transport?a. food molecules entering a cell via a food vacuole formed by the membrane * B. 
water molecules entering a cell through the membrane from areas of high concentration
* C. 
potassium ions entering a cell through proteins in the membrane requiring the use of ATP
* D. 
macromolecules entering a cell through proteins in the membrane from areas of lower concentration

passive transport is osmosis. This is a water specific process. Usually, cells are in an environment where there is one concentration of ions outside and one inside. Because concentrations like to be the same, the cell can pump ions in an out to stay alive.

Explanation:

one would be wind another would be water density

answer: glucoamylase presented optimum activity at temperature of 55â°c, and, in the glycosidic bonds from the non-reducing ends of starch, resulting in the production of glucose. source and type of fermentation can affect the enzyme's properties
