Answer: There will be change in the tube in which E.coli will be incubated and there will be no change in the test tube in which Shigella is incubated
Explanation:
Lactose Fermentation Test is done to see which bacteria ferments lactose. pH and color indicator is attached to observe the change. The pH goes slightly down because of formation of Acid and due to this reason a color change is also seen during this test.
As E.coli typically ferments lactose so there will change in color and pH in the test tube incubated with E.coli, while there will be no change in the test tube incubated with Shigella.
The step of the scientific method being described in the example is collecting and observing the data. This is an important part of the experiment, as it is going to be the basis of the analysis and conclusion. This is where the actual application of the hypothesis is going to reflect on. The data noted by the observer should be accurate and genuine.
Hello There!
This is called the "Thermosphere"
The thermosphere is the biggest part of the Earth's atmosphere. This layer is very important because it protects us on earth from UV radiation. UV radiation is harmful for humans skin and their hair. It is also extremely hard to breathe in this layer because the thermosphere is made up of mostly nitrogen and oxygen.
Aerobic Respiration occurs that is also known as the oxidation of glucose
