When brown iodine is exposed to starch it turns dark purple. In an experiment, you placed water and 10 drops of iodine inside a small bag made of dialysis tubing. Next, you placed the bag in a beaker with a cornstarch solution. The solution in the beaker turned dark purple. Select all that apply. the iodine moved into the beaker the iodine moved into the beaker the cornstarch moved into the bag the cornstarch moved into the bag iodine has a smaller molecular size than cornstarch iodine has a smaller molecular size than cornstarch cornstarch has a smaller molecular size than the iodine cornstarch has a smaller molecular size than the iodine the bag was selectively permeable
Control of Microbial Growth
It can be defined as the process to inhibit or prevent the growth of the population of microorganisms. It usually involves the use of physical and chemical agents to the growth of microorganisms. It is very important to control the growth of microorganisms, especially in the pharmaceutical and biotechnology industries, academic research, medical field, and food industry.
Sterilization
It is a method for the destruction of all forms of vegetative growth and endospores from a medium. In other words, sterilization can be defined as a method of killing every microbial organism such as bacteria, fungi, etc. present in an object or a medium. There are different strategies present to sterilize an object, like physical methods and chemical methods of microbial control.
